An electric tester is an electric device that is used to test and measure the electrical properties of an object. The construction of the device is usually based on an analog or digital voltmeter. The device is used for measuring the parameters of all the electrical and electronic devices.
Although an electric tester meter can be used for a variety of purposes, it’s most commonly used to find electrical problems. Electric meters are small and easy to use, and can help identify problems with wiring, outlets, switches, breakers, and fuses. If you’ve got an electrical problem, or you just want to know more about how your home works, an electric tester meter can help.

- Battery-powered testers
- AC-powered testers
Battery powered testers: These are small size devices that are being designed to suit in the palm of your hand. These devices are used in measuring the current or voltage parameters of the device. The devices are used in many fields such as automotive, networking, and in the engineering and data processing industries as well.
AC-powered testers: These are larger devices that are designed to be plugged into an AC power. Power testing meters offer a fast, accurate way to figure out the power consumption of something you’re working on. You can find them in several different types, but the most popular (and cheapest) are those that run on AC power.
Most of the electrical appliances and electronic gadgets around us are powered by electrical energy. It is easy to use a multimeter to measure the voltage, current, and other parameters of the electrical power, but how do you test the power itself? For this purpose, the AC power tester was invented. This device can test whether the electrical power meets the required parameters.
How to use a multimeter to check voltage
Knowing how to test a voltage with a multimeter is a great addition to your DIY toolkit. You don’t need to be an electrician to use a multimeter, but it’s a handy skill to have. When you’re trying to figure out if your washing machine has a short in the wire or if your car battery needs replacing, you can save time and money by knowing how to test a voltage with a multimeter. So, follow these steps to learn how to test a voltage with a multimeter.
If you’re an electrician, you need to know how to use a multimeter to check voltage. A multimeter measures voltage, resistance, and other electrical properties. It comes with a basic set of instructions that tell you how to use it. But when you’re working on a live circuit, you can’t afford to make a mistake. One wrong move and you could be in for an unpleasant shock. Below are step by step method to use a multimeter to check voltage
- Make sure the multimeter is on
- Connect the black probe to the COM or C and the red probe to the VAC or V
- The multimeter should display the voltage (in VAC or V)
- It should be somewhere between 0 and 500 VAC
