2. Features
This instrument is a digital clamp-on earth resistance tester, and it is used in multi-
earthed systems. Can measure the earth resistance by simply clamping around the
earthed wires.
This instrument also equips AC current function to measure current up to
30 A
same as our traditional leakage clamp meters.
A single earthing cannot be measured. (only for multiple-earthing system)
󱛠 Wide measuring range (Auto-ranging)
Earth/ground resistance Max.
1200 Ω Min. resolution 0 . 01 Ω
AC current Max. 30 A Min. resolution 0 . 1 mA
󱛠 Noise check function
A function to detect current, which effects on an earth resistance measurement
and display the NOISE symbol on the LCD.
󱛠 True RMS
Accurate true RMS readings of AC current with distorted waveform.
󱛠 Auto power-off function
A function to prevent the
instrument from being left turned on and conserve
battery power.
󱛠 Data hold function
A function to freeze the measured value on the display.
󱛠 Buzzer function
A function to give audible warning to the user when the measurement result is
10 Ω or less.
󱛠 Backlight function
A function to facilitate working at dimly lit areas.
󱛠 Memory function
A function to save and display the measurement r
esult.
󱛠 Designed to following safety standard.
