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 9209 installed in slot 8 of an NI cDAQ-9178 chassis

Slots 1 through 7 of the NI cDAQ-9178 chassis are empty

Note

For operational specifications, refer to the most recent
