input function
•
OFF
- no function of 0...10 Vdc input
•
extern setpoint
- 0...10 V dc input is converted into setpoint
1 according to set measuring range and setting of parameter
(ΔP/V) and k-factor
•
temp ctrl setp
- 0...10 V dc input is converted into tempera-
ture (-30.0...+70.0°C) for setpoint compensation
OFF
