Run-time calibration
•
2AI U High Feature
When setting the module parameters the runtime calibration for the 2AI U High Feature
analog electronic module can be enabled to compensate for component drift resulting
from changes in the ambient temperature. During the calibration interval, the updating of
new data is delayed by 250 ms. Calibration takes place each time the ambient
temperature changes by 5 °C.
•
2AI I 2/4WIRE High Feature
When setting the module parameters a runtime calibration for the
2AI I 2/4WIRE High Feature analog electronic module can be enabled for periodic
compensation of the offset voltage drift of the A/D converter. During the calibration
interval, the updating of new data is delayed by 200 ms. The accuracy limits of the
module will be met without run-time calibration.
