What size aquarium is suitable? Where to put the aquarium? A lot of things to consider for the first aquarist. If you are confused about choosing and setting up an aquarium then this guide will help clear the matter up. Especially common mistakes to avoid. The following article on LaoKoon Aquarium will help you better understand this information.
7 Principles of choosing an aquarium
1. What size aquarium is suitable?
Before we discuss the things you need to consider when choosing the right-sized aquarium, there is one thing I want to make clear. Choose the largest aquarium possible or as large as possible. This is something that a lot of beginners catch off guard. A large aquarium will be easier to care for than a small one.
In particular, you see, your fish will give off the waste. A lot and it’s inevitable. Waste includes:
- + feces
- + Small
- + Fish leftovers
As the waste decomposes, it produces chemicals that are toxic to fish. This is one of the main reasons we perform water changes to remove these chemical build-ups from the water. These chemicals build up faster in smaller aquariums than in large tanks.
Let’s use an example to make this concept easier to understand. Let’s say these chemicals are one teaspoon of instant coffee. What happens if you add this coffee to a cup of water? Does the water turn brown? But if you add the same amount of coffee to the swimming pool, there will be no noticeable change. A large amount of water dilutes the coffee to an unnoticeable level.
So does your aquarium these chemicals quickly build up and become dangerous in smaller tanks. You will need to perform maintenance correctly and regularly, which can be a huge requirement for any beginner.
A beginner chooses an aquarium of at least 15 gallons about 75 liters. Also, let’s take a closer look at what to keep in mind when choosing the ideal sized aquarium.
2. Where to put the aquarium?
Fish are unlike any other livestock on earth. What makes them unique is that they live in a heavy glass rectangle filled with water. Remember, once your aquarium is set up properly, avoid moving the aquarium as this is not only a huge pain but also stresses the fish.
It is for this reason that you should take some time to find the ideal place for your aquarium before placing it. We usually recommend finding out where you want your aquarium to be placed before you buy it because that location will affect the size, shape, and weight of the aquarium you can afford.
The right location for your aquarium depends on the following factors:
- + Size of the fish tank
- + Shape of the fish tank
- + The layout of your house
- + How you use your house
So the right place for my aquarium may not necessarily be the best place for yours. To make your life easier, we have 7 simple points you need to deal with when choosing the perfect spot in your home.

3. How much can you buy?
We will agree with you, the bigger your aquarium the more expensive it is to maintain like: + More water in the aquarium.
- + The bigger the fireplace
- + The larger the filter
- + More water conditioners to treat water
However, this depends on the type of fish and the number of fish to determine the budget to buy an aquarium. All of these add to the cost of the aquarium. As said initially, when it comes to aquariums, bigger is definitely better. But if you are on a tight budget, you may have to consider the size of your aquarium.
4. Size and type of fish
The size of the aquarium depends on the type of fish and the number of fish you keep. Take a goldfish as an example. An adult goldfish can grow up to 28 cm. If your fish grows too large for your aquarium, then you have two options
So buying the right sized tank from the start ensures that you don’t have to make a difficult choice later on. However, just because a fish is small doesn’t necessarily mean it’s right for your aquarium. Some fish are very territorial and will bully any fish that ventures into its area of the tank.
So, when deciding what fish you want to add to your tank, it’s important to do your research. You want to consider the adult size of your fish as well as their temperament. Your tank needs to have enough room for the largest and most aggressive fish you want to stock.
5. How big is the water surface of the tank?
Most beginner tutorials don’t even mention this point. Most likely because it’s hard to explain. But because it is so important, we simply had to include it in this guide.
You see, fish breathe oxygen. Like you. Like me. If you put more fish in the aquarium than there is available oxygen, they will suffocate. That’s understandable enough, isn’t it?
How oxygen gets into the tank is through the surface of the water. The larger the surface of the water, the more oxygen can enter the aquarium. And, the more oxygen there is, the more fish can live inside without suffocation.
In fact, the size of the aquarium usually doesn’t limit the number of fish you can keep, but rather the surface area of the water. That is, in addition to the minimum height, the number of fish in the tank depends on the surface area of the tank. If 2 tanks have the same water area, one is taller than the other, don’t be fooled that the taller tank will house more fish.
Experienced people will not choose a higher type of tank because it really does not have a decisive factor in determining the number of fish that can be put in the tank because the nature of these two tanks is the same number of fish.
Although there are a few ways to cheat and add a little extra oxygen, like using an air blower to aerate your aquarium. So, if you are choosing between two identical aquariums, choose one that allows for a larger water surface area.
6. Choose glass or acrylic aquarium?
We’ve been asked this question a lot, luckily, it’s a question with a simple answer. For any tank under 150 gallons about 570 liters of water, a glass tank should be chosen. And between you and me, I don’t think too many beginners will buy a larger aquarium than that.
Why do we recommend glass aquariums?
Basically, acrylic tanks scratch it can be too easy. Although the pebbles you put on the bottom of the tank can also make an aquarium. While acrylic aquariums can be easily repaired, they are prone to scratches during cleaning. And besides, with this size, the glass tank is much cheaper and easier to get.

7. Avoid the kits
Aquarium kits are sold everywhere. These kits will provide all the equipment needed for an aquarium also known as starter kits, but these are really the traps that beginner aquarists can sometimes fall into. get it from time to time An aquarium kit usually includes:
- + A fish tank
- + A filter
- + Fireplace
- + Light up
- + An air pump with an ice cube
- + A thermometer
- + A network
- + Air-conditioner water
All of these kits are often sold very cheaply at first it sounds appealing but the truth is, unfortunately over time 99.9% of these kits are very bad people are often attracted by the price and the uniqueness of these kits but the fact:
- + Not only the aquariums are often too small, but the auxiliary equipment is also messy.
- + The clip light on is broken after a week, the thermometer is not accurate, the filter is not working.. so give priority to buying a quality, reliable device to make it work stably for a long time to avoid to Unwanted fish death.

What color should the night light be? The question no one seems to ask because everyone assumes it will be the familiar warm yellow light. But no, choosing what color night light you have has many effects on nerves, physiology, and even feng shui. It’s interesting, isn’t it?
WHY DO WE NEED A SLEEP LIGHT IN SOME CASES?
According to the theory of biology, you should turn off the lights and lights when you go to sleep.
For some people, especially children and the elderly, turning off all lights is not necessarily a good thing. Example:
- Lack of light can make children afraid, difficult to fall asleep, sometimes when the baby suddenly wakes up and finds it dark, he may cry and have difficulty falling back to sleep.
- For the elderly with poor eyesight, it may be difficult to move and walk.
- There are many people who need a little light to fall asleep more easily.
WHAT SHOULD BE THE SLEEP LAMP SHOULD BE?
Recently, a study was conducted on the influence of color in the room on your sleep with the participation of 2000 people including both men and women.
Research shows that bedrooms with different colors affect your sleep differently. In which blue for the longest average sleep time per night is 7h52′ and purple for the lowest average sleep time of only 5h56′.
Based on the results of the above study, we can see that blue will help your sleep last the longest, but blue light is harmful to your eyes, so you should not use lamps with bright light. this when going to bed.
The best light for the human body is a yellow light. That’s why incandescent lamps with yellow light have existed for so long until the advent of LEDs, but only when LEDs come out with yellow light products will incandescent lamps be completely replaced.
Besides, as the study above, the yellow color of the bedroom helps your sleep time be longer, so the yellow LED light will be the right choice in the bedroom as well as a good night’s sleep.

NOTES TO CHOOSE EFFECTIVE SLEEP LIGHT FOR EACH SUBJECT:
1. For children
Children are quite sensitive subjects. You should note that your baby’s eyes always have an area called the “yellow spot” – that is, the sensitive spot. The light from the night light is too strong, causing the baby’s macula to be adversely affected, blue and white light can penetrate the lens and cause damage to the retina.
Night light with strong light will make it very difficult for the baby to fall asleep, or will not sleep deeply. When an infant sleeps, light can still penetrate the eyelids, greatly affecting the baby’s vision.
Many scientific studies show that the light of a night light will inhibit the secretion of melatonin (a hormone that helps children fall asleep). For a long time, it will negatively affect the health of the baby, making it difficult for the child to sleep. If you want your child not to be afraid to wake up at night by turning on a night light for your baby, you should choose a night light with a soft, dim orange color to ensure that your baby has good health even when sleeping.
2. For the elderly
As we age, sleep also changes. Older adults may feel drowsy earlier, wake up earlier, or be sleepless. Elderly people have reduced eyesight, so they need a sufficient source of natural light to avoid creating a feeling of darkness and mystery, which can easily create feelings of loneliness, depression and cause many adverse health problems.
At the same time, the night light also makes walking less difficult. Lights should be placed in the contiguous area between the bed, aisle, and toilet. If using artificial light such as LED lights, night lights, you should choose a type that emits soft light, bringing good sleep, body and spirit are fully rested.
3. Choose a night light for husband and wife to sublimate “s.e.x”
According to a survey of study, outstanding colors such as purple, red, and blue make couples most excited for sex. Accordingly, couples often have sex on average about 3.5 times a week when their bedroom is painted purple. After purple is red, couples have sex about 3.2 times per week. The blue bedroom ranks third with a density of 3.1 times per week.
The researchers said that the bedroom color that makes couples least interested in sex is gray when they only have sex about 1.8 times a week. But in fact, color not only affects sex life, but mood, desire, work… are also affected.
Therefore, if you sometimes want a little fun for “s.e.x”, you can completely innovate with purple, red, or blue night lights!

4. Choose a night light that is compatible with the five elements that are compatible with the owner
Although most night lights have yellow or pink tones, they are all good, but you can also choose the color according to your destiny for better feng shui. For example, if you have a Wood sign, then choose a light that leans towards blue, Earth is yellow, Water is black, and Fire is of course red, and Kim will be white.
In addition, homeowners can also use furniture with other five elements to increase prosperity for feng shui.
CONCLUSION: WHAT COLORS SHOULD BE LIGHT?
1. The most appropriate is to choose light colors such as light yellow, light orange that will make it easier for you to fall asleep.
2. Avoid the use of night lights with a white, blue, green, red light…
3. Use a lamp with a brightness level switch. You should not use night lights with only 1-2 brightness levels, that’s too little!
4. Night lights should use low-power lamps and bulbs.
5. Using lamps with lampshades, both increasing the aesthetics of the night lights, and reducing part of the light to avoid dazzling.
6. Use a night light with a solid base and body to ensure safety and aesthetics for the entire space.
Treat and prevent rust from your tools by following a few simple steps.
Your tools will last a lifetime if you take care of them, but one of the biggest enemies of metal tools is rust, which can be prevented if the right precautions are taken.
What is Rust?
Rust is the product of metal corrosion, where a chemical reaction creates an “oxide” that’s expressed as the well-known red- or rust-colored powder.
This oxidation process breaks down of the underlying material and should be controlled or eliminated as it will significantly weaken the metal over time. There are several ways you can prevent corrosion in the first place, as well as steps to take to remove rust from tools that have undergone oxidation.
How to Remove Rust
Tool owners should have on hand a multi-purpose oil designed to clean, lubricate, and protect. To remove light rust from tools simply apply oil to a rag and wipe the metal thoroughly. If the articulating parts are rusted, working the oil into rusted joints multiple times is usually effective.
- Drop some oil into the joint and manipulate the tool back and forth, open and closed, grinding the rust and lubricant into a slurry.
- Taking a clean side of the rag, wipe up the slurry from the joint and, to make the tool usable again
- Repeat the oil application and manipulate the tool until you’re no longer getting a mixture of rust and oil on the rag.
If the rust problem is on the surface of the tool, and not inside the joints, you can scrub the oxidation off.
- Use a wire brush, sandpaper, or steel wool to remove all traces of rust.
- Pockmarks and scaling are particularly hard to remove, so power tools like a drill with a wire wheel attachment or a bench grinder with a metal wire buffer wheel can make short work of deeply rusted tool surfaces.
- Once the tool is thoroughly stripped of rust, deep lubrication of the entire tool surface with a non-oxidizing oil like mineral oil and a wipe down with a rag will finalize the rust removal process.
Moisture control is paramount in rust prevention. Storing your tools in a dry place is crucial. A sub-grade basement in an environment with a high water table will keep humidity levels high, promoting the formation of rust. Not a good spot for tool storage.
While the hinges on a wrench are an obvious place for rust to occur, tool owners often don’t often think about the delicate motors and electric brushes inside of power tools, which are made out of copper and other corrosion-prone metals. Keep all your tools above ground—and inside—if possible, or install a dehumidifier in your tool storage area if it’s humid but it’s your only storage solution.
Regular lubrication and cleaning of hand tools with a petroleum product are the most basic steps an owner can take to extend the longevity of a tool. Sometimes a single drop of multi-purpose oil in an articulating joint or gear will ensure a lifetime of use, and a multi-purpose oil-soaked rag wiped over the surface of any metal parts spreads a thin layer of protection against the elements that cause rust.
Painting and sealing up metal parts that are exposed to the elements are also great methods to prevent corrosion and rust. While most manufacturers provide a layer of chrome or powder-coating paint, many old tools do not have this protective coating. Good prep work is important for ensuring a quality bond, but a sealant like paint or rubber can extend the life of old tools and provide a new gripping surface for a fairly low cost.
For a long time, trekking has become a popular form of tourism in the world. To have a safe and complete trekking trip, trekking teams need to carefully prepare the necessary trekking tools. If you still do not know what to bring, please refer to our article shortly.
Specialized mountaineering – The most important trekking tool
You need to determine in advance that this trip is not just a walk or sightseeing. Therefore, all preparations must be considered and thoughtful. A dedicated climbing suit with optimal protection will be a must when trekking. In addition, you should also buy yourself a dedicated climbing hat to protect your head from wind, dust, and possible impacts.
However, if you cannot invest in an expensive specialized outfit, you can completely wear your usual outfit. Ideally, you should choose well-ventilated, fast-drying, stretchy sportswear that suits the constant movements of the trekking person. The humid mountainous environment is easy to produce insects and reptiles. To avoid being squeezed, snakes, or mosquitoes, you should prepare pants and a long-sleeved shirt.
Tools for sleeping in the woods
Surely you will have at least 1 night to sleep in the woods or in the middle of an empty lot. The weather in the forest or in the mountains lowers the temperature quite deeply at night. At the same time, the sounds of animals and insects in the forest will make you very uncomfortable. So, you need to prepare in advance to have a good night’s sleep. Without a deep sleep to regain lost energy, you will become tired and lose interest at the beginning of the day.
Usually, trekking groups will choose to camp overnight. To save space and save energy during the journey, you can choose to buy the best backpacking tent. You should bring a sleeping bag for the cold weather to keep your body warm while you sleep.
Map, compass – trekking tools ensure safety
For the best safety, your trekking trip should be led by a local or by joining a tour with experienced guides. If you want to explore the dangerous path on your own, a map or compass is an essential tool for trekking. You will be in control of your trip, knowing where you have gone and where you will be coming next. Without professional navigation tools, you can mark your travels with your own symbols so you don’t have to go around wasting time.
Large backpack – an indispensable trekking tool
All personal items, food, drinks, or tools to prepare for trekking are put in a backpack. Therefore, you should choose a large backpack, designed with many compartments to easily divide furniture as well as convenient when needed. The weight of a trekking backpack is about 5 – 10kg. Therefore, you should choose a backpack with power belts. It will help you to support your backpack, avoid focusing pressure at one point, causing you back pain, shoulder fatigue.
Medical first aid tools and medicine
Continuously having to cross vast forests, climb over steep rocky slopes or wade in fast-flowing streams makes you more susceptible to falling or scratching. A trekking kit that is useful for you at this time includes bandages, tape, gauze, rubbing alcohol, antiseptic … In addition, you should bring special medicines such as fever, headache, anti-inflammatory, pain relief, … To avoid attracting mosquitoes and harmful insects, you should bring mosquito repellent cream, insect spray. If possible, strengthen your health, improve your resistance with vitamin C effervescent tablets or instant ginseng bags. You can use it at meals and at bedtime.
Super bright flashlight
You won’t know what might happen to you staying overnight in the woods. So add to your list of trekking gear a bright headlamp or handheld flashlight. When you see the surrounding space, you will feel safe and in better control of the situation. When choosing to buy a lamp, you should pay attention to the parameters that the production introduces such as brightness, the weight of the lamp, battery life, lamp durability, lamp size …
If you have to set up a tent to sleep overnight, the rope is an indispensable trekking tool in your backpack. It will make the tent more stable and not fall over if there is strong wind or rain. In addition, when your expedition crosses the mountains or streams, use ropes to connect members of the crew to avoid getting lost or injured.
If you have to climb steep or steep mountains, ropes will be the best trekking tool to help you move faster. Let someone with the best health and skills in the crew anchor the ropes to a firm position, then your trekking team will take turns climbing the ropes to overcome this difficult challenge.
If you are preparing trekking equipment and you forgot a climbing stick, it is a pity. Because you have to move a lot on dangerous mountain roads, your feet will easily get tired because the gravity is too great. Now let the walking stick share the burden and support your knees and feet.
On the other hand, the stick can also eliminate the risk of slipping in wet rainy weather, your steps will also be more secure and safe. If there are many obstacles and large puddles on the way, you can use a stick to explore the terrain before you step down. The climbing stick has now become an essential item when trekking with many smart designs, which can be shortened and stretched arbitrarily and save space when stored in a backpack.
Although there are many dangers, trekking is a type of tourism that many young people love to explore. To have a safe trip, bring lots of memories, do not forget to prepare yourself with the most necessary trekking equipment. Wish you were always happy and discover many interesting things.
The onset of 3D printing has really taken us by storm. I bet no soul could imagine advancing from the monotonous 2D printing that has existed for centuries. And as if that was not enough, they came up with the 3D pen as well.
To think that you can create 3D models using a simple handheld device is incredible in its own right. So, yes! 3D pens are worth it. Check out the quality review for a comprehensive buying guide on the best 3D pens.
Are 3D pens worth it?
To further fortify this point, I find 3D pens more than worth it for the following reasons:
3D pens complement 3D printing. Once you print a mega model using the 3D printer, the 3D pen allows you to add finer details to the model. As such, your artistic capabilities are expressed to the full.
3D pens are a perfect tool for enhancing the creativity of kids. Instead of buying toys all the time, let them make their own using the 3D pens.
Coming to adults, aside from the professional craftsmen, 3D pens help grownups to relax their mind as they explore their creativity. Therapeutic indeed!
The versatility of 3D pens cannot be overemphasized. Given they are handheld, you can create virtually any shape you can think of.
What is the best 3D pen to buy?
As earlier suggested, Reviews Rabbit lists the top 10 kick-ass 3D pens you should really consider investing on. These are:
3D Simo Kit 2 – perfect for architects
3D Simo MultiPro – good for multitasking
3D Simo Basic 2 – perfect for kids

Dikale 07A 3D Pen – most budget-friendly 3D pen
3Doodler Create+ – used by professionals
AIO Printing Pen – good for adults
CoLiDo 3D Pen – suitable for beginners
Scribbler Duo – perfect for artists
How do beginners use 3D pens?
As a beginner, you need to have the following items before getting started:
It is also good to understand how 3D pens function. The filament is pulled through the pen by the help of a motor. At the tip of the pen, the filament is heated up so it flows smoothly out of the nozzle. You need to press the button at the side of the pen to keep the filament oozing out. You can also adjust the speed of the pen to achieve thicker or thinner lines.
Having these tips in mind, you can:
Make whatever 3D object you wish.
You can also add raised decorations to household items like flower vases.
Repair items manufactured using 3D printers
Draw all kinds of geometric shapes and figures.
Is 3D printing expensive?
Regarding costs, there are quite a number of factors that dictate the costs of 3D printing. Perhaps the most obvious is the size of the object you intend to print. Larger objects end up being expensive because of the amount of filament and electricity used. Smaller objects are somewhat inexpensive to print.
A good 3D printer will cost you around $800, but there are models priced as low as $200
For animals like bats, cockroaches, raccoons, owls, and the Tasmanian devil, there is not much debate on whether they are nocturnal, diurnal, or crepuscular (fancy words, huh?). But for deer, the debate rages on – Are deer nocturnal or diurnal? Are deer crepuscular? That means twilight-active, by the way…
You’ll hear all sorts of answers from deer hunters – some mythical, others factual. I hope this piece by an expert from Airgun Maniac will demystify the age-old myths on the nature of deer.
First and foremost, it pays to understand these four terms:
- Nocturnal – most active at night
- Crepuscular – most active in twilight – i.e. that period in the evening between daylight and darkness
- Diurnal – most active during the day
- Matutinal – most active during the morning hours
Knowing what time of the day the deer are most active will help you schedule your deer hunting expedition better.
According to The National Highway Safety Administration, about 1.5 million deer-vehicle collisions occur every year in the US. The majority of these accidents occur between 6 p.m. and 9.00 p.m. Additionally, most of these accidents occur between October and December – what we roughly refer to as the deer season.
Numbers don’t lie. In this regard, it is evident that deer are most active in the evenings.
This fact is supported by one past study that concluded “Based on the rate of movement, deer had clearly defined crepuscular activity patterns.” This was after a three-year-long study of mule deer in South-Central Washington.
There is, however, a further twist to this crepuscular nature of deer. As evidenced in recent research by Erik P Ensing and others, deer may have a nocturnal or diurnal tendency on top of the crepuscular nature. The researchers found out that deer in Canada were mostly diurnal while deer in the Netherlands were mostly nocturnal. This difference was attributed to two major factors:
- Human disturbance
- Local weather
Human activity is chiefly what makes deer nocturnal. You see, hordes of hunters roam through the forests and thickets in search of deer. They leave their scent all over the place.
Being the sensitive animals they are, deer sense the looming danger and cleverly avoid these areas. Funny enough, the same deer may visit the spots where the hunters have been once darkness sets in.
And so, when you come in the morning and see the deer tracks and clues of feeding, you conclude that deer are actually nocturnal. In case you decide to hunt them only at night, you will have missed the mark.
Fact has it that deer never continuously sleep or rest for more than 12-15 hours. Be sure that when if seem not to spot them during the day, they are somewhere else feeding and moving. That’s all they can do with so much hunting pressure around. In the absence of hunting pressure, deer freely feed during the day.
Old is gold
As you may have realized, it is usually very hard to spot old mature bucks during the day. The fact that they have grown to such an age tells you how smart they are. They have been able to evade hunters season after season.
In fact, some come to open spaces only at night. Most of their daytime is spent in hideouts. On the contrary, the younger bucks who are not that clever try feeding during the day and are easily hunted down.
Deer are also known to come out of their hideouts when the weather is more convivial. This coincidentally happens at twilight in those regions with adverse daytime temperatures. The bed most of the day to avoid the wide temperature variations during the day.
Are deer supposed to be out during the day?
If a deer spots a predator during its favorite twilight hours, it may be forced to bed for the entire night, thus you can expect them to feed the following day during day.
Taking all these factors into account, you can now understand why some people claim that deer are nocturnal, while others claim that deer are diurnal. Make sure to study your specific hunting area to understand the exact behavior of the local deer. And don’t forget to check out Airgun Maniac for the best PCP air rifles in 2020 on the market.
A multimeter is an indispensable tool for electricians because it enables the electrician to control every possible electrical situation.
Also if you are not an electrician, but if you have a multimeter at home then it is really useful for checking sockets, switches, or other electrical equipment in trouble.
I would like to share with you about the multimeter, its functions, and the types available on the market today.
What is a multimeter?
It is an electrical testing tool with many different functions such as resistance, volts, amps.
Just as it performs various tasks to test, assemble, repair electrical equipment, electronic at the home, factory, Measuring device.
Applicable temperature and environment
- Low-cost weather station
- DMM internal temperature
- Measure high and low DC values
- Average Measurement from Peak to Peak and DC
- Measure DC
- True RMS AC
Measurement of resistor
- Small ohm meter
- Measure resistor with constant voltage
- Measure resistor with constant current
Time and frequency measurement
- Fast frequency
- Measure time
Types of multimeters you need to know.
Analog multimeter or call VOM (Volt-Ohm-Milammeter). The measured values are determined by the deviation of the indicator on the scale from the point ‘0’. This indicator is connected to an iron core. This iron core moves through permanent magnets. When the iron is moving at the same time the pointer moves. Before taking the measurement, you must correct the ‘0’ point. VOM is for simple measurements, with a large range of errors, so its cost is relatively comfortable.
Digital multimeter or (DMM). Its measurements are displayed on the LCD screen, the measurements are done through 2 probes, one black is always connected to COM port, red is connected port symbol (VΩmA) if it is It is used to measure voltage V, resistance Ω, small current mA or connected to the symbol port (A) if we want to measure large value A current (note the measuring current does not exceed the allowed value stated above digital multimeter)
Digital multimeter has high accuracy and is very safe, easy to use, multi-function. So nowadays most of them use a digital multimeter, but its cost is also higher than an analog multimeter. You should choose one that is suitable for your purpose.
Digital multimeter has two more types: clamp digital multimeter and auto-ranging multimeter.
Clamp digital multimeter
To measure the current on the device, you just need to turn the knob to the ‘A ‘position to switch to current measurement then hook the clamp meter to the wire to read the value. Very large currents can be measured depending on the permissible range of the meter. In addition, it can measure power, measure volts.
Note when using you must install in accordance with the scale.
An auto-ranging multimeter is a multimeter in which you can easily measure voltage and resistance without knowing its range in advance.
For example, if you want to measure the AC voltage, you just need to turn on the AC voltage scale without considering it in the range of 10v, 100v, 400v.
Above I have introduced you to know the types of the multimeter. If you are willing to buy you one then consider what your intended use is and what kind of watch it is suitable for on the market.
Wish you choose the right multimeter for you.
