How to Find the Best Multimeter [GUIDE]

How to Find the Best Multimeter: Top Picks for 2021

When working on circuits regardless of the kind, you must have a digital multimeter (DMM) beside you. This is because you can use it to measure some electrical units like the voltage, current, and resistance for both direct current (DC) circuits and alternating current (AC) circuits. Because of its multipurpose functionality and usage, it may sound like it is on the expensive side, but in reality, you can get various affordable multimeters for Kids in the market or in online stores like amazon.

Aside from measuring circuits, you can use it to troubleshoot circuits in an electronic project, but before you buy one, there are some things you should know.

The basic functions of a multimeter are to measure current, voltage, and resistance. However, it could as well measure the current in a diode, the continuity mode of circuits, frequency, capacitance, temperature, etc. The average measurement of your multimeter should be able to measure is 50mV and 20mA of current at the least and 1000V and 20A at the maximum. For instance, you can use it to check an LED that consumes 20mA. In measuring resistance, it should be able to measure from a few ohms to a few Mega Ohms.

If you have a battery in your car and after a while, it cannot hold full charges again, then you can simply use a multimeter to check the power it is storing. With this, you will know how long you can use it and when you will have to get a new one. The need for replacement will be when you find it with a voltage of 0.99V or less.

To be able to do this, you get your multimeter and locate the two probes on it. You will have to connect the probes to the terminals of the battery and the charge of the battery will appear on the screen of the multimeter.

However, if you find out there is an electrical issue in your car and you just checked the battery and found it to be in good working condition, then you can simply test other components of the circuit board like the motors, resistors, etc, and following the same pattern of connecting the probes to the two terminals too.

What can multimeters measure?

You can use the voltage across two points in a circuit, the resistance in a wire or circuit, and as well the current flowing through the circuit. It is this feature that makes them sometimes call it a “multitester”.

Several multimeters have a continuity check and give out a loud beep to show two things are connected electrically. This is very useful, especially when you are building a circuit and connecting wires or soldering; if you run a continuity check and you hear the beep, it means that all your work was carried out well and there won’t be issues of short-circuiting.

A diode is like a one-way valve that only lets electricity flow in one direction and some multimeters can check if it is functioning properly too. Though it may vary across different multimeters, you should find out in your user manual how it functions.

Finding the best Multimeters: Factors to consider when looking for kids Multimeter

It could be a tricky task to find the right multimeter for your electrical work or personal use since there exist numerous and different types in the market. However, we have outlined some tips here that would help you know the best one that will suit your needs. These tips include: –

1. Digital vs. analog multimeter

In the world of technology, there are digital products and analog products. In previous times, the analog products were widely in use till the invention of the digital but this does not mean that it knocked it out completely since there are still lots of people who prefer the analog to the digital. However, when it comes to getting a multimeter, it is advisable to go for the digital one as there are several reasons for that:-

  • The first reason is since you cannot see your measuring parameters easily since it possesses no screen like the digital. To see your values, you will have to manually and meticulously read a needle movement.
  • If you don’t have a steady eye, then you will not be able to read it accurately.
  • Additionally, you will need a training tutorial on the way to read values as the ones marked on it are quite condense and messy.

2. Auto range vs. Manual range

It is only when your budget is not wide or you are still a beginner that you can purchase a multimeter with a manual range as it is very stressful to work with. For the auto range multimeter, all you will have to do will be to connect the device, choose the parameter you wish to measure, and read the value that pops up on the screen while the multimeter will choose its range by itself

However, a manual multimeter is annoying and stressful as you will have to do all the work yourself. In a case when you have numerous values and components to deal with when carrying out a project, you will tire pout along the way. Hence, you should save yourself this stress and get one with auto range.

3. Safety features (CAT safety measures)

When using electronic or electrical tools, you must pay utmost attention to safety. As a beginner, it is advisable to work on DC circuits first before you can begin working on AC.

However, when you are measuring high currents whether on DC or AC circuits, then you should look for a professional and high-quality multimeter. This is because they come with some features that not all multimeters possess. Some of these features include;

  • The type of fuse in the multimeter. The average fuses used in plugs are the glass fuses, but these are not reliable, and you should steer clear of them. However, the more reliable form of fuses in multimeter is the high-quality cartridge fuses, and these are paramount if you want to measure high current or low currents since they can resist bursting or causing a fire outbreak.
  • Secondly, you should check if it has a CAT III rating, which tells that the multimeter will not explode when you mistakenly decrease the mains.
  • Finally, the probes of the multimeter should be of high quality, i.e. they should be made from silicone rubbers.

4. Range limits

The ranges that your multimeter can measure should also be checked so that after using it in for a particular project, it can as well serve in another one and you will not have to purchase a new multimeter. For instance, you could buy a multimeter that can measure currents in milli-range and you originally bought it for amperes. This will cause you to go get another which can do that.

Hence, you should check out these recommendations for the ranges you should seek in a multimeter.

  • Current Range: 10uA to 10A
  • Resistance Range: 10 Ohm to 20MOhm
  • Some picofarad to a decent high range (maybe in milli-range)

There is no specific range measurement of voltage since it is not advisable to use them for measuring high voltages. Rather, you can simply use your multimeter to measure voltage from a few millivolts to 600V.

5. Input resistance

The input resistance of a multimeter is the resistance it offers to the device connecting across its probes and if the resistance is high, then you should know that you have a good multimeter. The average input resistance on a multimeter is at 1MOhm.

6. Input Impedance

This is one of the features several people ignore when buying a multimeter and this can lead to a lot of issues. For instance, you buy a multimeter with a few 100k ohms impedance and you want to measure a circuit with high impedance ranging to about 1M ohm. Once you connect your multimeter probes across such a circuit, it will disorganize the whole circuit and this will decrease the effective resistance so it is advisable to get one with 10M ohm input impedance at the minimum.

7. Accuracy

The accuracy of the multimeter is not a very important feature when choosing one though the average multimeters have and accuracy of A 0.5% DC volt with 4000 or 6000 counts. If you get one with a higher value than this, then you have just wasted your money to get an unprofessional multimeter.

8. Diode Measuring feature

If you access the diode or continuity function symbol on your multimeter, you will find this feature. A majority of the multimeters have this function, though their voltage range is about 2V instead of 4V like the average multimeter and that is a problem.

9. Continuity response time

Your multimeter should have a quick response time to prove its superiority and professionalism. This is necessary when dealing with short or open circuits as slow response time is very annoying and confusing.

10. Battery time

This is one of the most important features you should look out for. If the battery of your multimeter cannot last for more than 1000 hours, then you have a wrong multimeter.

11. Auto hold function

This is the ability for the reading you take with your probes to still be visible on the screen even after you have removed the probes. This is very good, especially when you are trying to connect your probes carefully and avoiding to touch an open wire.
