When turned ON, the instrument performs self-calibration. The jaws of
the clamp must therefore be closed and not clamped around any
conductor.
If the instrument fails to complete self-calibration, the error message Err.
CAL is displayed. If this happens, turn the instrument OFF and ensure
the air gaps are clean. Then turn the instrument ON.
2.2. IMPEDANCE AND CURRENT MEASUREMENT
Set the
switch to
Ω+A .
Press the trigger to open the jaws,
and clamp around the conductor
that is part of the ground system
to be measured.
When the jaws are open, the
symbol is displayed and the
instrument cannot make a
measurement.
