The Kyoritsu 4200 Earth Clamp Tester features the noise check function to detect current that can influence an earth resistance measurement.
The earth resistance from 0.05 to 1200Ohm can be measured without the auxiliary earth spikes.
True RMS - accurate true RMS readings of AC current including distorted waveform from 1mA to 300A
Noise check function - A function to detect current, which effects an earth resistance measurement and display "NOISE" mark on the LCD.
Memory function - save and display up to 100 measurement data
Data hold function / buzzer function / back light function
Compliant with safety standards of IEC 61010-1 : CAT IV 300V Pollution Degree2
Note: A single earthing can not be measured - only for multiple earthing systems
