How to Use the Clamp
This section is about how to set up the Clamp for Earth
resistance tests, AC leakage current measurements, and the
Fluke Connect

Wireless System.
The Clamp includes a trigger lock on the trigger. Push the jaw
trigger lock and trigger together to open the jaw.
Ground Resistance Measurements
The Clamp generates a voltage to the system under test and
the induced current in the system is measured by the Clamp.
The Clamp uses Ohm's Law (R=U/I) to automatically calculate
the resistance measurement.
To check the Clamp before ground resistance measurements:
1. Position the Jaw on the Standard Loop Resistance. See
Figure 7.
