Electrical testing is not all that hard if you have the right knowledge and, of course, the right equipment. Here are some tips to help you get started:
• The first concern is your safety. You do not want to take risks where electricity is concerned. There are some things you need to make sure before you start any electrical job. Always remember to turn off the power before starting. For this, you can either trip the circuit breaker or remove the main service panel fuse. After turning off the power, make sure that the power is indeed off by using an inductive voltage detector. Hold the detector near each wire and press the clip. If the detector lights up or beeps, the power is still on.
• Now that you are sure that the power is off, you will need to plug in your devices. If you are planning to check for current at receptacles, it is safer to use an outlet analyzer rather than a voltage tester. After plugging in the device, if the LED lights up, it shows that current is present. Now check both slots for the presence of current.
• Do not use both hands to hold the voltage tester while checking for current at receptacles. Hold the tester with the tips of your fingers- like the way you hold a chopstick. This will prevent the danger of electric shocks.
• Also make sure that your voltage tester is working before you attempt to perform any electrical test. Try the tester in a live circuit first and make sure that it lights up and is in proper working order.
• To take reading, you will need to use a multimeter. A digital multimeter is much more convenient and accurate than an analog one. The display panel of a digital multimeter displays voltage or resistance, depending on the test being performed. If the multimeter has an auto ranging feature, the meter will automatically be calibrated to the proper range; otherwise you’ll have to do it manually.
• In case you are using an analog multimeter, you will need to first set it to zero to eliminate needle error during testing. Also make sure that the correct scale is set for the test you are performing. To set the meter to zero, turn it on, join the two probes and make proper adjustments so that the needle points to zero.
• You can also use an alligator clip to free one hand, which makes conducting tests much more convenient. Moreover, these clips can also help reduce the electric shock hazard by keeping your fingers away from live connections.
• Make sure you place the multimeter on a non-metallic surface so that the readings are accurate.
• While performing electrical tests, it is essential to use the correct electrical test equipment. You need to know whether you require a low voltage device or a high voltage device. Using a high voltage device on a low voltage circuit may damage it. Also make sure that the device is properly used and stored.
