NI 4071 7½-Digit FlexDMM Calibration Procedure
9.
Reset the calibrator for safety reasons.
10. Call the niDMM Cal Adjust Miscellaneous VI.
You have completed adjusting the AC voltage modes of the NI 4071. Select one of the following
options:
•
If you are performing additional adjustments, refer to the following section, as applicable:
–
•
If you are
not
performing additional adjustments, refer to one of the following sections:
–
—to verify your new calibration coefficients before saving
them to the EEPROM
–
Completing the Adjustment Procedures
—if you do
not
want to verify the adjustments
you have just made
Adjusting Current Modes
If you do not use the current modes (DC and AC), or the accuracy is insignificant for your
application, you can skip this section and select
one of the following options:
•
If you skip this section and you want to verify the new calibration coefficients before saving
them to the EEPROM, repeat the
section (except for
).
•
If you skip this section and you do not want to verify the new calibration coefficients, go to
the
Completing the Adjustment Procedures
section.
Note
The 90-day DC current uncertainty of the Fluke 5720A is not adequate to
calibrate the four lowest DC current ranges listed in Table 25. You must characterize
the calibrator output to better than published specifications. Use metrology
laboratory methods to obtain the required uncertainty. Monitor the current applied
using a DC current shunt/voltmeter system in series with the calibrator output. Refer
to Table 13 for the recommended DC current uncertainty requirements for the DC
current shunt/voltmeter system.
