2. Setpoint setting:
External differential voltage
with
internal reference potential
(COM), i.e. REF1- and REF2- are connected to 0V-potential.
Thus the differential voltage is always formed between REF+
and COM.
Internal resistance Ri = 24 k
Ω
Example:
Setpoint = (REF1+) – (REF1-)
Setpoint = (-7 V) – (0 V)
Setpoint = -7 V

3. Setpoint setting:
Internal +10 V reference voltage, i.e. the setpoint can be
adjusted from 0...+10 V by means of setpoint potentiometer.
