Measuring and control behaviour
of the controller during calibration
During calibration the actuating out‐
puts are deactivated. Exception: a
basic load or a manual control vari‐
able has been set. This remains
active. The measured value output
[standard signal output mA] is frozen,
corresponding to its settings in the
mA output menu.
When calibration/testing has been
completed successfully, all of the
error checks relating to the measured
value are restarted. The controller
saves all the determined data for zero
point and slope upon a successful
calibration.
