Measuring channel settings
This descriptions of [Channel 1] apply
correspondingly to the settings in all
other measuring channels. The proce‐
dure for entering the settings for the
channel in question is identical, how‐
ever the parameters to be set may
differ. Your attention is drawn to the dif‐
ferences, which are also described.
Display tolerances
Display tolerances between the sensor
and/or measuring device and controller
must be calibrated with sensors and/or
with output signals from measuring
devices that do not require calibration
or where calibration is performed in the
sensor/measuring device. The relevant
information for this is contained in the
respective operating instructions for the
sensor or measuring device.
Cancelling the calibration process
with ESC
ESC can be used to cancel an ongoing
calibration process at any stage. The
controller then continues to operate
with the last calibration result detected
as valid.

Calibration of the measuring
channels
The calibration processes are identical
for all measuring channels. However, it
is necessary to calibrate each meas‐
uring channel separately.
