Applications
The clamp meter is one of the essential test tools in daily maintenance work. It is mainly used to test voltage, current, frequency and other related parameters, requiring it to have higher test resolution, test accuracy and more test functions. Applications mainly include industrial control, industrial equipment, commercial, industrial and residential electrical systems, and HVAC.

Tips: True RMS Zero Input Characteristics of Clamp Meter
To test the measurement of a sine wave signal, the true RMS measurement method has less error than the traditional averaging response method. True RMS clamp meters accurately measure sine waves, but when the signal under test is not being input (AC voltage function selected, input shorted), the AC function may show a reading between 1 and 50. These deviated readings are normal. They do not affect the accuracy of the clamp meter in measuring AC over the specified measurement range. True RMS requires a certain level of input signal to make a measurement. Therefore, the AC voltage and current ranges are specified between 2% and 100% of the full range.
