Menu name Description
Displ.range C1 unit
This parameter is used to define the
flow rate unit. It must have a length of
at least 5 characters.
Displ.range C1 start
The start of the display range is
defined with this parameter.
Displ.range C1 end
The end of the display range is defined
with this parameter.

Channel 1 menu.
This function allow the flow rate to be measured by means of an effective pres-
sure procedure on a measuring panel. The differential pressure is a measure for
the flow rate:
q = Δp
