MODEL 4200 - Earth Clamp Tester

The earth resistance from 0.05 to 1500? can be measured without the auxiliary earth spikes. (The Multiple Earthing System.)
True RMS Accurate true RMS readings of AC current including distorted waveform from 1mA to 30.0A
Noise Check Function A function to detect current, which effects on 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

Over-range indication	"OL"is displayed when input exceeds the upper limit of a measuring range
