OVERVIEW
23
•
Do not demagnetize while the GCP-530 or GCP-
1030 is clamping a conductor to be measured.
Demagnetizing causes current to flow into the
conductor, which may damage parts in the
circuit to be measured.
•
Check that the conductor being measured is not
clamped when supplying power to the GCP-530
or GCP-1030 for the same reason. Demagnetized
waveforms are generated when supplying
electric power.
4. Without clamping the conductor to be
measured, press the opening lever until the
"UNLOCK" indication disappears, and check
that the sensor head is properly closed.
5. Press the demagnetizing switch (DEMAG) on
the terminator.
6. Turn the zero adjustment dial on the terminator,
to adjust the trace to the zero position.
7. If zero adjustment is not possible in step 6, turn
the coarse adjustment trimmer to bring the trace
within the range of adjustment by the zero
adjustment dial.
