Run-time calibration
2AI U High Feature
Run-time calibration can be enabled at module parameterization for the 2AI U
High Feature analog electronic module to adjust for component drift due to
changes in ambient temperature. During the calibration interval, new data
updates will be delayed for 250 ms. Calibration takes place every time there is a
5° C change in ambient temperature.
2AI I 2/4WIRE High Feature
Run-time calibration can be enabled at module parameterization for the 2AI I
2/4WIRE High Feature analog electronic module to periodically adjust for the
offset voltage drift of the A/D converter. During the calibration interval, new data
updates will be delayed for 200 ms. The accuracy limits of the module will be
met without run-time calibration.
