5.5.1.3 Characteristic curve C1 (menu expansion)
NOTICE!This menu is available only for devices with a differential pres-
sure channel.
The menu changes depending on the set operating mode of the measuring
channel.
The menu expansion is not present for devices for which the parameter 'Mode'
has been set to the value 'Linear'.

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 .
