Types of Electrical Testers and their Uses

The professional electricians use a variety of testers to check the range of electricity functions in commercial and residential electrical wiring, and the DIY homeowners also find the testers useful. Knowing these testers, knowing their functions, and getting to know how they are used, expands their expertise when it comes to working on electrical wiring. Some testers are single-function devices that they can perform a single function while some are multi-function to perform common electrical testing duties. Various electrical testers can be used to check voltage levels in both DC and AC circuits, short circuits and open circuits, polarity, and test for amperage.

Wand voltage meter

Wand voltage meter

This meter is only owned by professional electricians. The tool includes a wire similar to those found in a multimeter or neon voltage tester which can be used to measure continuity by touching the leads to the metal contacts or the bare wires. A wand meter is an expensive tool that is often found in the toolboxes of the pros but it is very advanced where every DIYer will want to own.

Digital clamp meter

Digital clamp meter

It is a tool that is used normally by professional electricians though it has combined the function of the multimeter with a current sensor, which makes it more expensive. Between the multimeter and the clamp meter, there are differences but the obvious one is that this tool has a clamping jaw that grips wire conductors. The tool is easier and safer when it comes to working inside an open circuit breaker panel when testing individual circuits. It also has features that are used in the same manner as the standard multimeter. This digital meter is a special tool that few homes will want to own.

Multimeter

Multimeter

This is the most versatile electric testers that can test any different testing functions. Most of the multimeters, provide precise readings of resistance, continuity, capacitance, AC and DC voltage, and frequency. The multimeter has a boxy body with analog or digital readout, a dial setting the test function as well as the voltage and various readout settings, and two long leads with metal probes at their ends. The tester has a wide range of accuracy and quality and it makes sense to invest in a quality tool.
