C Series Calibration

Last Modified: May 2, 2019

Your device uses software calibration to adjust the software scaling of signals read from and produced by your device. Using a precise reference signal, your device measures and calculates scaling constants for analog input and analog output. The scaling constants are stored in nonvolatile memory (EEPROM) on your device. NI recommends that you calibrate your device just before a measurement session but after your module has been powered on and warmed up for at least 15 minutes. You should allow this same warm-up time before performing any calibration of your system. Frequent calibration produces the most stable and repeatable measurement performance. The device is not harmed in any way if you recalibrate it often.

  • Calibrating your device takes some time. Do not be alarmed if the Adjust C Series Calibration function/VI takes several seconds to execute.
  • For best results, stop any ongoing tasks and disconnect any unnecessary external connections before running calibration.
  • The NI 9205 and NI 9206 are calibrated using the M Series calibration process.

C Series devices do not self-calibrate or automatically calibrate. You must use a manual procedure to calibrate these devices.
