Offset Accuracy Adjustment
Complete the following procedure to adjust the offset accuracy performance of the NI 9203.
1. On the NI 9203, connect AI3 to COM.
2. Adjust the NI 9203.
a. Initialize a calibration session on the NI 9203. The default password is
NI
.
b. Input the external temperature in degrees Celsius.
c. Call and configure the NI 9203:Offset adjustment function according to Table 7 to
adjust the offset for both the Unipolar and Bipolar ranges.
d. Close the calibration session.
3. Disconnect AI3 from COM on the NI 9203.
EEPROM Update
When an adjustment procedure is completed, the NI 9203 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
Worldwide Support and Services
for assistance in returning the device to NI.
