Before the first calibration, the following has to be determined:
- the calibration procedure (1-point or 2-point calibration)
whether the process value output is frozen or not during calibration.
Chapter 21.2 "Analog inputs - C111", page 61.
If subsequent calibrations are carried out with the same settings,
then it will not be necessary to set them again.
"Freezing" the process value output means that, during calibration, the output
signal is held at the value that was produced immediately before calibration
started. This is to avoid an uncontrolled reaction from any PLC that may be
connected to the output of the indicator/controller.
While the process value output is frozen, the lower display shows "donE" after
the last calibration step, and the upper display shows the latest measurement.
The process value output remains unchanged!
After the chlorine cell has been installed once more, the
pressed. The process value output is now coupled to the display again.
The factory setting is: "Calibration without frozen process value
output".
Press the key repeatedly, until "C211" appears in the lower display.
