3.3 Demagnetizing and Zero Adjustment
(1) With the waveform measurement instrument input at ground, adjust
the trace to the zero position.
(2) Set the input coupling of the waveform measurement instrument to
DC.
(3) Connect the output connector of this instrument to the input
connector of the waveform measurement instrument. Turn the
collar until it clicks, and check that it is locked securely.
• When disconnecting the output connector, be sure to
release the lock before pulling out the connector. Forcibly
pulling the connector without releasing the lock, or pulling
on the cable, can damage the terminator.
• When inputting the signal into input terminals other than
BNC connectors, make sure the polarity is correct.
• Do not demagnetize while this instrument is clamping an
insulated target conductor to be measured. Demagnetizing
causes current to flow into the insulated target conductor to
be measured, which may damage parts in the circuit to be
measured.
・
Check that the insulated target conductor to be measured
is not clamped when supplying power to this instrument for
the same reason. Demagnetized waveforms may generate
when supplying electric power.
