Types of Voltage testers

There are four types of voltage testers with different features and functions: digital multimeter, clamp meter, plug tester, and tick tracers.

As electricians, we have a lot of different testers that we use out there. And there are tons of various reasons we might have one tester over another or have some advanced and expensive test equipment versus some old ones. But, among cheaper types of equipment, there are four essential pieces of technology that you will come across. Most electricians have one or all of these four types of equipment or probably a mix of three, but these are the main ones you need to understand.  So first, we are going to start with the digital multimeter.

1) Digital multimeter

If we measure the voltage of a battery (AA) Use the black probe into the port; COM, and the red probe into the port; mAVΩ.  Now set the multimeter dial selector to “2V” in the D/C range (direct current). Next, connect the black lead to the battery’s ground wire and the red lead to the power or positive wire. Next, touch the leads with pressure on both sides against the positive and negative terminals of the AA battery. We have got a fresh battery here, you may observe the reading around 1.5V on the display screen of the digital multimeter. (the battery we are testing is brand new, so the voltage is slightly higher than 1.5V). We probably use a direct current (D/C) method instead of alternating current (A/C) with a digital multimeter.

A tester is something that you will probably use all day, every day, or everywhere you go. You may keep this tester in your back pocket probably more than anything. If you do construction, if you do service doesn’t matter. We can say, almost every electrician out there has some kind of tester or one of them.

2) Clamp-Meter

The multimeter has a clamp on it in this device, so it’s a clamp-on Amprobe or a clamp-on ammeter. The cool thing about this is that you can put this clamp-on ammeter over a massive conductor. So if you have got a service panel and have a 500 mcm or kc mill, depending on where you learned the terminology. You can clamp around those big conductors and see how much current is flowing through them.

Whereas most of the other small testers are just going to have a small jaw that you could put like number two or maybe one, not depending on what brand you are using. But different multimeters have clamp-on styles, and the ability for it to clamp is excellent. Because you can hang it on things, instead of holding the meter with one hand and then using the other probe in the other hand. So, you can clamp it and both hands are free to work, without any tools in your hand.

Now with amperage, usually when you have a clamp-on ammeter, you will not use the leads to test amperage around a load. So usually, you are just going to get a hold of a wire and put that thing around it. You have to make sure if you are going to put a wire in; there are two trim lines on the multimeter, so it will tell you that this line is kind of the optimal place.

3) Plugin voltage tester

Having a plug tester on, you don’t have to get the leads, turn the little dial, get everything set up, and try to plug in and find the right spot just to get a reading. No! you just take this plugin tester. The best feature is that it has a bunch of different configurations, so it lets you know if you wired something back if you went hot to neutral or you switched your hot and your ground, or there’s a whole bunch of different configurations, but you’re going to use this all the time. The other distinctive feature of plug voltage testers is that if you get the one with the gfci button.  It will simulate a fault condition to the ground, so it will trip a gift.

4) Tick Tracers

The tick tracers are something more if you have many conductors coming out of a junction box, and we are trying to identify which one is on or off. At a panel, we are turning breakers on and off, and when this beeping stops. They just shut it off, turn it back on, beeping starts again and turns it off so the beeping stops, therefore, this is the same wire that they’re on. It’s more of a tool just to trace down something than it is to tell you whether or not a circuit is dangerous or not for that if you ever think okay the tick tracer just shut off it’s telling us that the power is off. We stick our hands on this hot wire,  or if the wire is off, you can still get shocked. So you have to be very careful when you’re using them anytime.

We just always pull our tester back out, and we verify because we have readings that give me data to know for sure whether or not there’s the power between one wire and another wire, so it’s always smart to just double-check, but it’s an excellent tool to verify if you’re ever trying to figure out to know the breakers. If you have so many wires, the tick tester will tell you which one is hot. You have your tick tracer on you, and it’s not just a tick tracer for 120 volt 240-volt stuff. It goes all the way up to a thousand volts, and there are two different settings on it, so you’ve got the red setting which is anything from 70 volts up to a thousand, which is normal, line voltage that you are using for plugs and switches and stuff everywhere else. But there is also the blue option, and that’s 12 volts, and more, so it goes twelve to a thousand. It’ll still do everything in that range, but it also goes down to 12 volts.

So these are the four pieces of test equipment that you need to know as you are getting into this trade that’s how to use them for their basic functions.

Best Voltage Tester Buying Guide

i) Voltage Range:

The most important and best feature to consider is voltage range while buying a voltage tester. The voltage range tells you about the voltage values that you will measure. For example, if you want something versatile, then a voltage range of 12 volts to 1000 volt A/C will be better than 50 volts to 1000 volt A/C is much better in most variable conditions.

ii) Safety measures:

If you use a voltage tester, you are highly likely to work with a high voltage current to ensure safety at work. The most reliable feature of a voltage tester that includes safety compliance is CAT III and CAT IV. Although you can also find CAT III 1000 and CAT IV 600, some testers have CAT IV 1000V ratings for safety measures.

iii) LCD/ LED Display:

Display plays a vital role while taking measurements. For example, give actual voltage readings in addition to LED voltage ranges.

Frequently Asked Questions
How do we know that the voltage tester is working?

A voltage tester works by sensing the amount of current capacitively coupled from the live circuit to the tester and back to the ground by holding the tool. You are the ground reference through capacitive coupling. So when the tip glows red, and the tester device beeps, that determines the voltage is present.

How accurate is the voltage tester?

The AC power line voltages can vary plus or minus 5% or more. An example of this variation is a voltage measurement taken at a standard 115 V of A/C receptacle.


The function of a voltage tester is to check the voltage output of any given circuit or electrical appliance, which is essential for safety and for ensuring that all types of equipment have a certain amount of voltage. Therefore, we have already chosen the best voltage testers in this article. Among all these various voltage testers, you will discover their essential features and functions and an essential buying guide; with the help of this, you may choose a suitable voltage tester for you. First, however,  this detailed information will help buy the best voltage tester for your tool kit.
