Settings for [Channel 2]
In its 2-channel version, the controller
has two measurement channels. This
description for [Channel 1] applies
correspondingly for the settings in
[Channel 2]. The procedure for
making the settings for the channel in
question is identical, however the
parameters to be set may be different.
Differences are pointed out and are
also described.
Display tolerances
Display tolerances between the
sensor and/or measuring device and
controller have to be calibrated with
sensors and/or with output signals of
measuring devices that do not require
calibration or where calibration is per‐
formed in the sensor/measuring
device. The relevant information for
this is contained in the respective
operating instructions for the sensor
or measuring device.

Calibrating measuring channel 1
and measuring channel 2
The calibration processes are iden‐
tical for measuring channel 1 and
measuring channel 2. However, it is
necessary to calibrate each meas‐
uring channel separately
