- The earth resistance from 0.05 to 1200Ω 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
Note:
A single earthing can not be measured. (Only for Multiple Earthing System)
