• The earth resistance from 0.05 to 1500Ω 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)
