V1.2
Address Description Format
6 Enable/disable the offset of the voltage analog output:
0=offset disabled (default, 0…1/0…5/0…10 V)
1=offset enabled (0,2…1/1…5/2…10 V) Bit
7 Sets the direct or reversed correspondence between voltage
analog output and pressure:
0=direct (default, Min. V

Min. press., Max. V

Max.
press.)
1=reversed (Min. V

Max. press., Max. V

Min. press.)
