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
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
Wireless System.

Based on the electromagnetic induction principle, the Clamp
has a ring-shape current transformer comprised of a metal
core and coil winding. The current transformer senses the
magnetic field produced by the current or by the vector sum of
the currents flowing in the conductor under test. The current
transformer then produces a current proportional to the current
flowing in the conductor.
For an AC leakage current measurement test:
1. Open the jaw and make sure the jaw is free of dust, dirt, or
any foreign substances.
2. Turn on the Clamp.
3. Push to select the A function.
4. Attach the Clamp to the electrode, conductor, or ground
rod for measurement. Figure 9 shows several connection
types for an AC leakage current measurement.
