You have completed adjusting the DC voltage and resistance modes of the
NI 4070. Select one of the following options:
• If you want to perform additional adjustments, go to the
Voltage (AC- and DC-Coupled) Modes
section if you have opted not to adjust AC voltage.
•
If you are not performing the AC voltage or the current adjustments,
go to the
calibration coefficients before saving them to the EEPROM.
•
If you do not want to verify the adjustments you have just made, go to
the
Completing the Adjustment Procedures
Adjusting AC Voltage (AC- and DC-Coupled) Modes
Note
If you do not use the AC voltage modes for any measurements, or the accuracy of
these modes is irrelevant, you can skip this section in the calibration procedure and go
directly to the
section.
To adjust the AC voltage of the NI 4070, complete the following steps:
1.
Reset the calibrator.
Caution
Step 2 must be performed correctly to avoid shorting or electrical shock from
high voltage on unconnected spade lugs.
2.
Connect the calibration cable assembly with the connector block
plugged into the NI 4070 and with the spade lugs connected to the
