Operation

Note: Ensure that the jaws are fully closed before testing.

Note: DO NOT clamp on to any conductor or open the clamp jaws during the start-up

self-calibration (self-cal is identified by the LCD counting down from CAL7 to CAL1).

Ground Resistance Measurements

1. Open the clamp jaws and check that all

surfaces are clean and free of dust, dirt, or

any foreign substances. Clean if necessary.

2. Forcefully snap the clamp jaws open and

closed several times.

3. Turn the meter on by moving the rotary

switch to the ohms Ω

ΩΩ

Ω position. DO NOT

interrupt the start up procedure by opening

the clamp jaws or clamping around a

conductor. During self-calibration, the meter

will display CAL5, CAL4, CAL3, CAL2 and

CAL1.

4. Once the start-up calibration procedure is completed, the meter will sound a beep.

Clamp on to an electrode or ground rod and read the value of ground resistance on

the display.

Ground / Leakage Current Measurement

1. Turn the meter on by moving the rotary switch

to the mA or A position.

2. Clamp on to the electrode or conductor

3. Read the value of leakage current displayed

on the LCD.

HOLD

Press the HOLD button to freeze the reading in the display. H will appear in the display.

Press HOLD again to exit the function.
