In data acquisition processes, calibration of the measurement devices is very
important to maintain its accuracy. Users can calibrate the analog input
channels under the operating environment to optimizing the accuracy of the
9116 series card. The following section will guide you though the calibration
process for the 9116 series card.

Note: For an environment with frequently large fluctuations in temperature

and vibration, a 3 months re-calibration interval is recommended. For
laboratory conditions, 6 months to 1 year is acceptable.
