Self-calibration adjusts the PXIe-4190 for variations in the module environment. Perform a complete self-calibration after the first time you install the PXIe-4190.

The PXIe-4190 modules are externally calibrated at the factory but you should perform a self-calibration in all of the following situations:
  • After first installing the PXIe-4190 in a chassis
  • After any module that is in the same chassis as the PXIe-4190 is installed, uninstalled, or moved
  • When the PXIe-4190 is in an environment where the ambient temperature changes. Refer to the module specifications to find the allowable ambient temperature for your instrument.
  • When the PXIe-4190 temperature has drifted from Tcal by more than specified since the last self-calibration. Refer to the module specifications to find the allowable difference from Tcal for this instrument.
  • More than 24 hours have passed since the previous self-calibration
  1. Install the PXIe-4190 and let it warm up for the recommended warm-up time listed in the module specifications.
    Note Warm up begins when the PXI Express chassis has been powered on and the operating system has completely loaded.
  2. Self-calibrate the PXIe-4190 by clicking the Self-Calibrate button in Hardware Configuration Utility or MAX, or calling niDCPower Cal Self Calibrate or niDCPower_CalSelfCalibrate.
