Issue Details

When I try to perform an external calibration with my card in LabVIEW, I receive an error similar to what is shown below:

Error -200718 occurred at unidentified location
Possible reason(s):
Measurement taken during calibration produced an invalid AI gain calibration constant.

If performing an external calibration, ensure the reference voltage value passed to the calibration VI or function is correct. Repeat the calibration. If the error persists, contact National Instruments Technical Support.

 

 

Solution

The error indicates two action items to check for which are listed below:

  • Ensure the calibrator input is correct. There are specific voltage values that the calibration procedures specify. If the value is incorrect, the error will pop out.
  • If the error persists after confirming the procedure and inputs, the device is likely experiencing a hardware issue, and it should be returned for evaluation and repair (RMA)
