Configure the calibration mode for an analog input module using the C Series Module Properties dialog box for the module. Available options are Calibrated and Raw.
  • The Calibrated option configures the FPGA I/O Node to return calibrated, fixed-point data for the analog input module.
  • The Raw option configures the FPGA I/O Node to return uncalibrated, binary values for the following analog input modules.

When Calibrated is set to Raw, you must convert the binary values into meaningful engineering units and apply calibration constants. for higher accuracy. Convert and calibrate the values in the host VI.

The binary data returned by some modules is already calibrated. The following table lists the modules that return calibrated, binary data.
