4. Read the measurement results displayed by the clamp meter.
After you flank the cable or conductor with the jaw clamp meter, you can see the results of the electric current measurement on the clamp meter screen. If you are using an analog clamp meter, you should read the measurement results by following the scale corresponding to your chosen measurement mode and range.
If you use a digital clamp meter, you can read the measurement results directly on the LCD screen. Also pay attention to the unit of measurement displayed by the clamp meter, whether in amperes (A), milliamperes (mA), or microamperes (μA). If the measurement results displayed by the clamp meter are unstable or fluctuating, you can use the hold feature to freeze the measurement results on the screen.
If the measurement results displayed by the clamp meter do not make sense or do not match your expectations, you can try changing the measurement range, measurement mode, or jaw position of the clamp meter. If the measurement results remain incorrect, you can check whether there is damage or error in the clamp meter, cable, conductor, or power source you are using.
5. Record the measurement results you get.
After you get accurate and stable measurement results, you can record the measurement results for analysis, improvement, or reporting purposes. You can also take a photo or screenshot of the measurement results displayed by the clamp meter if you want to save it in digital form.
If your clamp meter has a memory feature, you can save the measurement results automatically on the clamp meter and access them anytime you want. If your clamp meter has a wireless communication feature, you can send the measurement results directly to other devices such as computers, smartphones, or printers via Bluetooth, Wi-Fi, or infrared.
6. Remove the jaw clamp meter from the cable or conductor for which you measure the current.
After you finish measuring the electric current using a clamp meter, you must remove the jaw clamp meter from the cable or conductor for which you measure the current. Carefully open the jaws of the meter clamp and remove it from the cable or conductor.
Make sure you don’t touch potentially dangerous parts like exposed ends of wires, hot conductors, or power sources that are still on. If necessary, you can turn off the power source first before removing the jaws of the clamp meter.
7. Turn off the clamp meter and store it well.
After you remove the jaw of the clamp meter from the cable or conductor, you should turn off the clamp meter to save battery and prevent damage. You can turn off the clamp meter by using the button or switch on the clamp meter. If your clamp meter has an auto power off feature, you do not need to turn off the clamp meter, because the clamp meter will automatically turn off after a few minutes of not use.
After you turn off the clamp meter, you should store the clamp meter well. Clean the clamp meter from dust, dirt, or liquid that sticks. Store the clamp meter in a dry, clean, and safe place. Keep the clamp meter away from sources of heat, moisture, or strong magnetic fields. If necessary, you can use a special box, bag, or suitcase to store the clamp meter.
