Earth Resistance Clamp Meter

2.Earth resistance measurement

1. After switching on, the instrument is automatism in
measurement current mode, you can press the▼Ω
button to configure for resistance measurement mode.
2. Hook the clamp jaw around earth leads or electrode
to be tested.
3. If symbol " - - - " and symbol are shown on the
display, it indicates that the clamp is closed incompletely.
You must press the trigger of the instrument several
times to close the clamp jaw correctly. After the
symbol disappears from the display, then it is in the
normal measurement mode.
4. Read the measurement value on the display.
5. When the display appears the "NOISE" symbol, it
indicates that there is an interference current in the
loop, the resistance measurement is not assured.
