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
With sensors or with the output sig‐
nals of measuring devices that do not
require calibration or where calibra‐
tion is carried out in the sensor/meas‐
uring device, display tolerances
between the sensor or measuring
device and the controller need be bal‐
anced. The relevant information
hereto is contained in the respective
operating instructions of the sensor or
measuring device.

Calibration of measuring
channel 1 and measuring channel 2
The calibration process is the same
for measuring channel 1 and meas‐
uring channel 2. Each measuring
channel must be calibrated independ‐
ently, however the calibration proce‐
dure is the same for both measuring
channels.
