User Manual

OVERVIEW

• 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.
