Scaling
The “teaching” scales
the analog output (4 to
20 mA) for a part of the
measuring range. This
allows you to optimize
the resolution for the
analog measurement
range. Only the current
and error output will be
affected by the 2 point
calibration. Therefore
you define a new start
and end for the mea-
surement range. This
“teaching” procedure
can be performed live
via the select key or via
pin 9 of the connector.
i
With a user defi-
ned output sca-
ling you can use
the error output,
see Chap. 5.2.3,
as a programma-
ble limit switch.
