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

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 9207 installed in slot 8 of an NI cDAQ-9178 chassis
•
Slots 1 through 7 of the NI cDAQ-9178 chassis are empty
Note
The test limits listed in Tables 4 and 7 are derived using the values in
Table 10.
