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.
Back E This represents the output (exit) of the
menu. Press 'back' to return to the
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

The root extracted input signal is shown as a signal from 0 … 100 %. The dis-
play value can be furnished with a different unit with the parameter
Displ.range C1 unit ´. The display range can be scaled to this unit with the
parameters Displ. C1 start and Displ.range C1 end .
