5.3 Operating modes
The unit provides 2 selectable operating modes for flow measurement:
Operating mode
[ModE]
Display unit
REL
% of the taught range
GAS
m/s, l/min, m
3
/h
The selected operating mode has no effect on the temperature measurement, only
absolute values in °C are indicated.
When [ModE] = GAS is selected:
u
Define the internal pipe diameter.
u
If required, calibrate curve of measured values.
When [ModE] = REL is selected:
u
Carry out flow adjustment.
The parameter settings are saved in the respective operating mode, i.e.
when the operating mode is changed, the settings are not lost.
5.4 Calibration
Via the calibration factor [CGA] the sensor can be adjusted to a reference flow in
the application.
The customer-specific calibration allows changing the gradient of the curve of
measured values. It influences the display and the outputs.
