Buying Guide - How to get the Best Multimeter Under 100 USD

Safety precautions

if you’ve ever experienced how painful an electric shock can be, then you can definitely agree safety should be given the #1 priority when it comes to the multimeters. Other than just ourselves, the safety precautions that we observe should also be able to protect the multimeter itself.

General precautionary measures you should always observe.

When you are not using the digital multimeter, you should always ensure that the knob is in the off position which is also the highest voltage position.

When it comes to checking for any hazardous voltage in an electrical circuit, it is important that you do so for the AC and DC voltages

When it comes to voltage check, here are some of the things to take into account.

First off, you should not touch the bare tips of your probes together since this will lead to a short circuit which could damage the multimeter.

If you prefer to go for manual ranging multimeters, then you should make sure you choose the appropriate range. This normally has the multimeter scale reading near midway on the scale. Other than this, you should also go ahead and check for both the DC and AC voltages on your multimeter scales.

Selecting a lower range than that of the component you are measuring will result to the multimeter reading showing a 1. If you have a reading that is out of range, then the best thing for you to do for a DC circuit is start with a higher value then drop down the scale till you settle on the correct value.

When connecting the probes, ensure the banana probe of the red lead is in the correct port. Ig you happen to have it plugged into the current socket of the multimeter, then you may experience a short circuit as you take the voltage measurement.

Checking for continuity

Even though most people do not do this, it is always best that you do a continuity check before you start any measurement activity with the multimeter.

It’s quite simple…

For continuity, you first have to be certain that the reading on your digital multimeter is zero after you connect the leads. When checking for continuity, first of all, switch off any power supply to the circuit. Just in case there is any charged capacitor present in the circuit the beeper will sound until the capacitor is drained.

It is recommended that you always confirm the presence of a capacitor in your circuit in order to avoid any confusion. Conversely, if you change the black and red leads, the readings should remain the same.

Measuring resistance

Like most of the readings you’ll be measuring when using a multimeter, you should ensure that the power is turned off before you measure resistance.

Though you don't have to do this all the time, it is best that you measure a resistor alone since if you have other components connected to the circuit, you may affect the resistance reading. For you to get the correct and accurate resistance reading, also ensure that all the capacitors connected in the circuit are drained.

Current measurement.

Other than voltage measurement, multimeters are expected to measure current just as conveniently.

First off, you should ensure that the multimeter is connected in series (we’ll be looking at correct multimeter usage shortly).

With the knob set to the current measuring mode and the right current set before measuring the current, you won’t risk blowing up the fuse within the multimeter. Something else that you need to be cautious about is measuring the mains current since this is quite dangerous to you and the multimeter.


After you are done measuring current and want to switch to voltage measurement, ensure that you switch the knob to the voltage mode since not doing so would be a potential hazard.

Here’s how the test leads should be.

Before taking into account the design of the multimeter, let’s take into account a really overlooked accessory- the probes and test leads.

You probably have never considered the fact that probes and test leads could be quite significant, right? Well, to cut to the chase, the truth is no matter how good your multimeter may be or how much money you might have spent on it, having poor functioning test leads could be quite the risk.

If for instance, the probes do not have a safety rating of the power circuit you are measuring, you could really hurt yourself. The safety rating of the meter does apply to the leads, the test probes, the clips and even the clamp on.

Ensure that the multimeter has got safety certification

When it comes to certification, most people go for the meters that have IEC 61010 certification which, despite being satisfactory, may at times end up disappointing you. This is so because in most cases, multimeter manufacturers may self-certify their meters to meet the standards. As a result, a meter that may be labeled as a CAT III-600V may actually not be as good as you may expect it to be when it’s passed through independent testing in the lab.

Here’s what you should do…

When you want to get the safest multimeter, you should go for the meters that have undergone independent certification in a laboratory. The best of these are the UL and the CSA. Before the multimeter is certified, it has to meet the recommended tests which are why you should always go for the independent tests.

How to use a Multimeter

Other than just having the knowledge of which multimeter is safe for you and which ones not, you should also know how to use one. Before we move on to this, let’s have a look at the parts of a digital multimeter.

The display.

First off, there is the display. This one usually has got four digits and whereas some multimeters will have a low count when it comes to the display, some have as high as 6000 counts.

Other than this, some multimeter manufacturers go a notch higher to give their multimeters a backlit display feature. This normally allows you to be able to use your meter conveniently in low light areas.

The selection knobs.

Voltage and current are the main electrical units that a multimeter is expected to measure almost flawlessly. In order to do this, you’ll be needing the selection knob. If you have the autoranging multimeter, you’ll need to set the range on your own. On the other hand, if you’re lucky enough to have the autoranging multimeter, the range is normally set for you automatically.

The ports

Whereas a multimeter may be having two probes, the same does not go for the ports. At every point when taking the measurement, you’ll have the probes plugged into two of the ports at one point. The COM port normally has the black probe plugged into it which in turn goes to the ground or rather the negative end of the circuit in most cases.

When measuring large currents, you’ll be using the 10A port and by large, I mean anything that’s greater than 200mA. On the other hand, the mAVΩ is the port in which we conventionally have the red probe plugged into. This port will normally allow current measurement up to 200mA, voltage as well as resistance measurement.

Probe types on a multimeter.

Upon purchasing a multimeter, it'll normally come with probes but these are not the only types of probes you can use on the multimeter. Let's take a look at some of the probe types each of which can be used to make a given task twice as easy to handle.

Alligator clips

If you need probes to connect to large wires on a breadboard, then these are definitely what you should go for. They are able to hold on to the components you are operating on hence the best when it comes to handling long-term operations. You won't have to worry about holding the probes on the test components which brings us to our next type of probes.

The test probes.

You’ll normally get this with most multimeters. Besides being cheap and easy to replace, they’ll be quite handy when taking most measurements both industrial as well as just basic home maintenance.


Other than just having the alligator clips and the normal test probes, the banana to tweezer probes will also come in handy. Just in case you’ll be needing to test the SMD components, these are what you ought to go for.

Finally, there is the banana to IC hooks.

One fact that we can definitely agree upon is that it can be quite a hassle to operate on the legs of ICs. Taking this into account, it can be quite convenient to have the IC hooks with you as compared to using the normal test probes.

Measuring resistance

Normal resistors are color coded but the truth of the matter is that at one point of the other, you are bound to be confused no matter how experienced you are when it comes to electronic. First off, the colors may not be that clear and secondly, if you need to do something in a rush, you’ll need a multimeter to assist you in measuring the resistance.

In order to take resistance, ensure that there is no current running via the circuit. Just like you do when taking most measurements using a multimeter, the black probe should be in the COM port and the red one in the VΩmA port switch on your multimeter and turn the dial to the resistance mode. Which is normally indicated by the ohm symbol.

If you have a manual ranging multimeter, you’ll have to set the range of measurement yourself. If unsure, start with the highest value and drop down the scale to get it correct. On an autoranging multimeter which should also be the best multimeter under 100 for you, all you have to do is select the unit of measurement, which in our case is resistance, and let the meter do the rest for you.

Resistance is non-directional and it does not matter which probe goes where on the circuit. Place each probe at either end of the circuit you want to test. If your meter reads close to zero, the range is too high for you to get a good measurement hence you should adjust the dial to a lower setting. If the range is too low, the reading is 1 or OL meaning the meter is overloaded or out of measurement range. In this case, turn the dial to a higher setting

Measuring voltage

Voltage measurement is necessary when carrying out basic home maintenance or also troubleshooting industrial electrical components.

Here’s how you should go about when measuring voltage:

Plug the black probe into the COM port and the red one on the VΩmA port. Switch on your multimeter and regarding the type of voltage you are measuring, turn the dial setting to either AC or DC voltage mode which is indicated by a V with a straight line.

Unless you have an autoranging multimeter, you’ll have to set the range yourself. Conversely, for the manual ranging multimeters, setting the range should be done with respect to the settings present on the dial list.

If for instance, you expect to measure a voltage that's more than 2 volts but less than 20 volts, you should set the dial to the 20-volt setting. On the other hand, if you are not sure of the amount of voltage you are measuring, start with the highest setting.

The red probe should be on the positive terminal of the component you are measuring and the black one on the negative one. Too high a range might give you inaccurate readings.

On the other hand, if the range is too low, the multimeter will read 1 or indicate OL meaning that it is either overloaded or out of range in which case you need to turn the dial to a higher setting.

Testing for continuity

A continuity test is simply what tells us whether or not two electrical components are connected or not or rather whether or not there is a continuous flow of current in the circuit. If the continuity test is negative, it means that there is a flaw somewhere in the circuit and it could be caused by something as simple as a bad solder joint or a blown fuse.

Plug the black probe into the COM port and the red one in the VΩmA port. Turn the multimeter on and turn the dial to the continuity mode which is indicated by three arcs.

For continuity test, the multimeter sends a little current through the load. If the circuit is complete, you’ll see a zero on the screen and if otherwise, there’ll be a 1 or OL (open loop) on the display.

Just like resistance, continuity is also non-directional hence it does not matter how the probes are connected.
