Calibration Interval
The NI 9237 should be calibrated at a regular interval as defined by
the measurement accuracy requirements of your application. National
Instruments recommends that you routinely perform a complete calibration
at least once every year. You can shorten this interval based on the accuracy
demands of your application or requirements of your processes. Adjusting
the calibration constants must be done by a factory calibration at NI.
