Like a multitester and insulation resistance tester, there are analog
and digital types of clamp meters.
The measuring range is typically about 20A to 200A or 400A both for DC and AC. As a special type, there are products allowing for the measurement of a higher current of 2,000A.
Some types are also available to allow measurements of
fine current of few milliamps for the purpose of detecting leakage
current. Others allow the measurement by true RMS values for
measurement of current of distorted AC waveforms other than of
sine waves, for inverter power supply and switching power supply.
