VOLTAGE TESTER

Voltage tester is a tool to measure the flow of electric current involving small neon bulb with two insulated wires attached to bottom of bulb housing. It is used to check the functionality of the circuit. Battery voltage testers are expected to be accurate up to 500 volts. They bear the resistance capacity of 40ohms or so while their measure range is 90-1000 and above.

A plug tester looks like a small box with lights on the front while a plug on the back. To test the outlet, tester has to be plugged into the outlet. Lights on the front illuminating in a specific pattern depict the trouble regarding the outlet.

A no contact tester looks like a rectangular pen. To determine the test voltage, the pointed end of the tester has to be touched while putting it against the outlet. As a result of the present current, the tester will either light up or beep. Although it is the easiest type of tester to use, but it tends to bit more expensive than other type of such electricity detectors.
