Figure 1. Accuracy Verification Connections AO x + AO x – NI 9269 Set the DMM to read DC voltage in the minimum range required to cover the NI 9269 output range of ±10 V. Acquire a sample. Create and configure an AO voltage channel according to Table 2. Table 2.
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.
