6. Demagnetizing switch (DEMAG)
This can demagnetize the core if it has been magnetized by
switching the power on and off, or by an excessive input. Always
carry out demagnetizing before measurement.
Moreover, the demagnetizing process takes about 3 second. During
demagnetizing, a demagnetizing waveform is output.
7. Zero adjustment dial (ZERO ADJ)
Use the zero adjustment dial to correct for the effect of a voltage
offset or temperature drift on the instrument.
When beginning measurement, after demagnetizing always carry
out zero adjustment
8. Output connector
The current waveform of the measured conductor is output at a
constant rate (0.01 V/A).
Connect to the BNC input connector of the waveform measuring
instrument.
•
The output of this instrument is terminated internally. Use
the waveform measuring instrument with high impedance
input. With an input impedance of 50
Ω
, accurate
measurement is not possible.
•
If using BNC-banana plug adapters or similar to connect to
input terminals other than BNC connectors, make sure the
polarity is correct.
•
Turn the collar of output connector until it clicks, and check
that it is locked securely.
9. Power plug
Connect this to the power receptacle of PS-52 or PS-54 POWER
SUPPLY to supply power to the sensor part or the terminator part.
