Description
Ext. reference
This setting determines how large the offset is when input signal is at min.
This setting determines how large the offset is when input signal is at max.
Define how the external reference signal is used
0 = V->SH: Displacement of SH reference given by External voltage signal.
1 = V->Temp: Displacement of temperature given External voltage signal.
Define min. reference Voltage
Define max. reference Voltage
