Set the Calibration Mode to Calibrated in the C Series Module Properties dialog box for the NI 9208 if you want the FPGA I/O Node to return calibrated, fixed-point data from the module in units of amps. Set the Calibration Mode to Raw if you want the FPGA I/O Node to return calibrated, binary data from the module. If you set the Calibration Mode to Raw, you must convert the binary current values to amps. You must convert these values in the host VI.
You can use the following equation in the host VI to convert binary current values to amperes:
Amps = Binary Value × 0.022 A ÷ 8,388,607
|where||Binary Value is the value returned by the FPGA I/O Node.|
