Signal 1
Select and adjust the parameters and values for

 the selected 

sensor

 

Auto-detect...

Start automatic sensor identification
If you select auto-detect, the sensor identifies itself: type 
and sensor range are transmitted to the device. If no 
automatic detection is possible, the type and range of 
the sensor can be adjusted manually.

 

Type

:

Select the sensor type by choosing between:
Off:   no sensor type is selected
VFS:   Flow rate sensor: sensor for detecting flow rate
RPS:  Relative Pressure Sensor: sensor for detecting 

relative pressure

DPS:  Differential Pressure Sensor: sensor for detecting 

differential pressure

 

Range:

Select the sensor range.
The range depends on the previously selected sensor 
type (see tables to the left).
