An electric tester is device specifically designed to test and measure electrical conditions. Some electrical testers are simple while others are more complex. Electrical testers provide an easy way to check electrical conditions before repairing a live circuit. However, how do you make sure you end purchasing the best electrical tester?
My pick for the best electrical tester would be the Fluke 117 Multimeter
Let’s see the other types of electrical testers available in the market
Circuit testers are used for testing AC outlet load handling capabilities. They are used to determine whether the circuit is good or not. They are the most reliable tool to verify if a circuit is complete.
Appliance testers are more complex testers used for voltage and continuity tests. The tests done by the appliance testers ensure safety of electrical tools and appliances. Some of the tests done include insulation test, functional load test, hi-pot flash test, touch current test among other tests.
Phasing testers are used on both grounded and ungrounded AC systems to check high voltage fuses, test for the absence of high voltage on de-energized apparatus or testing for correct phase connections.
Voltage testers are sued to check the presence of voltage in the equipment being tested. Most of these voltage testers are specific to AC or DC voltage. A voltage tester consists of a small neon bulb with two insulated wires. The wires are attached to the bottom of the bulb housing. Voltage tester can be used to determine whether adequate voltage is flowing in a wire. Also, the tester can be used to check if there is current flowing through a wire as well as test for grounding.
Testers used to check if an electrical path can be established between two points. The power has to be turned off when doing the test.
Continuity testers are the safest tools that help with tracing wiring and testing switches. A continuity tester has a battery and a light bulb plus a wire lead.
High pot testers
High potential test, as it is commonly referred includes a number of instruments used to verify electrical insulation in appliances that could produce an electric shock should they fail.
Phase rotation testers
Phase rotation testers are used to check the rotation direction of polyphase electrical systems. They ensure the equipment is connected properly to the mains power supply.
Safety measures to observe before opening any electrical box
These are the two main safety measure that everyone should observe:
Switch off electrical power at the main panel
Double check that you have switched off the right circuit. The best tool to use would be a non-contact voltage.
According to a government report, one person dies every week in a construction-related electrical accident. Therefore, it would be important observe some safety measures when using the electrical testers.
Having recommended the Fluke multimeter, how do you go about using a non-contact voltage tester?
The first thing to do is to confirm that the power is off from the mains electrical switch and secondly, confirm you switched off the right circuit. The tester will light and/or produce some noise when it comes near to a live wire even if it’s covered in plastic insulation.
Confirm the batteries are working first before using the tester.
