App
Index
1.
Have the power supply 701934/700938, and oscilloscope or recorder for
waveform measurement ready.
2.
Turn the power switch OFF and connect the power cord.
3.
Connect the power plug of the 701930 to the power receptacle of the
701934/700938.
4.
Turn the 701934/700938 power switch ON, and check that the front panel
power indicator lights.
Note
The output of this unit is terminated internally. Use a high-impedance input to the
measuring instrument. With an input impedance of 50 Ω, accurate measurement
is not possible. When power is supplied to the 701930, a demagnetizing waveform
might be generated.
Demagnetizing and Zero Adjustment
CAUTION
• When disconnecting the output connector, be sure to release the lock before
pulling the connector. Forcibly pulling the connector without releasing the lock,
or pulling on the cable will result in damage to the terminator.
• If using BNC-banana plug or similar adapters to connect to input terminals other
than BNC connectors, make sure the polarity is correct.
• Do not demagnetize when the clamp is connected to a conductor. Doing so
might damage the components of the circuit being measured.
• Do not begin supplying power to the 701930 after the clamp has been connected
to a conductor. Doing so might damage the components of the circuit being
measured.
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 the 701930 to the input connector of the
waveform measurement instrument. Turn the clamp lever until it clicks,
and check that it is locked securely.
