Continuity Loop Test

5 Continuity Loop Test
The testing procedures are the same as ground resistance measurement:
Open the jaws and make sure the jaw mating surfaces are clean and free of
dust, dirt or any foreign substances.
Snap (open and close) the jaws a few times to ensure the jaws mate properly.
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.
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.
When the ground tester is ready, a beep sound will be heard.
Clamp on to the electrode or ground rod to be measured.
A beep sound will be heard if resistance R g is less than 40 Ω.
