3.5.5 Setting Range operating mode
General
The settings are possible if the Range operating mode is switched on (see 3.5.4). The
pressure gradient of a dosing (1) can be monitored and displayed for each connected
sensor with three different measurement ranges (see Fig. 4).
The dosing is judged to be error-free if the pressure gradient (1) of the dosing (as shown)
is within the tolerances determined by ranges A, B and C.
In the event of an error, the error LED (9) illuminates if the set error threshold has been
reached.
The measurement starts (adjustable for each sensor) either when a pressure threshold
is reached or via a signal applied to the system plug (4) (see 3.5.2).
Monitoring of the three measurement ranges can activated and deactivated individually
for each sensor.
