✅ The earth resistance can be measured from 0.05 to 1200Ω without auxiliary earth spikes. (Applicable for Multiple Earthing Systems.)

✅ True RMS provides accurate readings of AC current, including distorted waveforms from 1mA to 30.0A.

✅ Noise Check Function detects currents affecting earth resistance measurements and displays a "NOISE" indicator on the LCD.

✅ Memory function stores and displays up to 100 measurement data.

✅ Data hold function, buzzer function, and backlight function are included.

✅ Complies with IEC 61010-1 Safety Standards: CAT.IV 300V Pollution degree2.

Note:
Single earthing cannot be measured. (Only applicable for Multiple Earthing Systems)
