Execute/confirm
The
red
LED blinks briefly once to
indicate that a function is being
performed. After completion, the
unit returns to standard operation.

Select function/data
The
green
LED indicates standard operation
of the option module. Four different levels
can be selected.
Press the
key to change between levels.
The LED blinking pattern indicates which
level has been selected.

4 mA/20 mA ammeter
Zero calibration
The electric zero is adapted to the mechani
-
cal zero. As a result, a 4 mA signal is also
issued at Δp = 0 bar corresponding to the
pointer's zero point.
Zero can be calibrated in the scale range
between approx. –5° and 135° (see
Fig. 12).

The

Span calibration
The measuring span can be calibrated con
-
tinuously without affecting zero or the mea-
suring accuracy (see Fig. 12). The pointer
position corresponds to the end point with
20 mA output signal.
As a result, the end points can easily be
adapted to the measured medium, especially
when attachable or multiple dial plates are
used.
