Voltage Testers and Meters – Applications and Selection Criteria
Voltage testers and meters are essential diagnostic tools for electrical installers and other professionals working in the power industry. These terms are often used interchangeably by both sellers and users, but they do not mean exactly the same thing.
- A voltage tester (also known as a tester) is a simple, handy device that signals the presence or absence of voltage in electrical installations (e.g. with an LED diode).
- A voltage meter (also known as a voltmeter) allows for safe, easy and quick measurement of voltage values in electrical installations. They show the measured value on the display. More advanced models additionally provide resistance and frequency measurement.
To choose the best voltage meter for everyday work, it is worth focusing on:
- measurement range ,
- measurement accuracy ,
- additional functions , such as built-in memory, phase sequence indicator or lighting,
- measurement category (CAT) - a key safety element that determines what applications (test environment) a given measurement tool is intended for,
- durability and ergonomics .
