5 Continuity Loop Test
The testing procedures are the same as ground resistance measurement:
n
Open the jaws and make sure the jaw mating surfaces are clean and free of
dust, dirt or any foreign substances.
o
Snap (open and close) the jaws a few times to ensure the jaws mate properly.
p
Turn the power on, and set the rotary switch to the “Continuity” position.
Do not clamp on to any conductor or open the jaws at this moment
or during self-calibration.
q
At powering on, the clamp-on ground tester will self-calibrate for better accuracy.
Users should wait for the self-calibration to finish before making measurements.
During the self-calibration, the LCD will show CAL7, CAL6,..., CAL2, CAL1.
r
When the ground tester is ready, a beep sound will be heard.
s
Clamp on to the electrode or ground rod to be measured.
t
A beep sound will be heard if resistance Rg is less than 40
Ω
.
