Using the Clamp
Ground Resistance Measurements
To perform ground resistance measurements:
1. Open the jaws and make sure the surfaces fit together properly and
are free of dust, dirt, or any foreign substances.
2. Turn the Clamp on by moving the rotary switch to the Ω function.
Note
Do not attach the Clamp to a conductor or open the jaws now or
during self-calibration or calibration will be interrupted.
3. After power is turned on, the Clamp self-calibrates for better
accuracy. Wait for self-calibration to finish before making
measurements. During the self-calibration, the display will show
CAL7, CAL6,…..CAL2, CAL1. The Clamp beeps when self-calibration is
completed.
4. Attach the Clamp to the electrode or ground rod to be measured.
5. Read the value of R
g
(ground resistance) from the display. Figure 3
illustrates the ground resistance measurement principles.
Note
• If self-calibration does not stop, check the jaw surfaces for
dust or dirt and power up the Clamp again.
• If there is more than 3 A or 30 V in the ground rod, the jaw
icon and the word NOISE flash on the display and the
Clamp beeps. When noise is present the Clamp reading is
not valid.
• If the jaw assembly is opened during measurement, the jaw
icon appears on the display.
