NI 9269 Calibration Procedure
EEPROM Update
When an adjustment procedure is completed, the NI 9269 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.
Reverification
Repeat the
section to determine the As-Left status of the device.
Note
If any test fails Reverification 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 values in the following table are based on calibrated scaling coefficients, which are stored
in the onboard EEPROM.
The following accuracy table is valid for calibration under the following conditions:
•
Ambient temperature 23 °C ± 5 °C
•
NI 9269 installed in slot 8 of an NI cDAQ-9178 chassis
•
Slots 1 through 7 of the NI cDAQ-9178 chassis are empty
