AC Leakage Current Measurement
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.
5. Read the value of the leakage current on the display.
