7
h.
Repeat steps d through g for each calibration voltage in the array.
i.
Close the calibration session.
4.
Disconnect the NI 9215 from the calibrator.
5.
Repeat steps 2 through 4 for each channel on the NI 9215.
EEPROM Update
When an adjustment procedure is completed, the NI 9215 internal calibration memory
(EEPROM) is immediately updated.
If you do not want to perform an adjustment, you can update the calibration date and onboard
calibration temperature without making any adjustments by initializing an external calibration,
setting the C Series calibration temperature,
and closing the external calibration.
Re-Verification
Repeat the
section to determine the As-Left status of the device.
Note
If any test fails Re-Verification after performing an adjustment, verify that
you have met the
before returning your device to NI. Refer to
for assistance in returning the device to NI.
Accuracy Under Calibration Conditions
The following calibration specifications are valid under the following conditions:
•
Ambient temperature 23 °C ±5 °C
•
NI 9215 installed in slot 8 of an NI cDAQ-9178 chassis
•
Slots 1 through 7 of the NI cDAQ-9178 chassis are empty
Note
The limits listed in Table 4 are derived using the values in Table 6.
