1)
Do not connect pin 3 and pin 6 for normal operation of the gauge. These
pins are reserved for adjustment of the setpoint potentiometers
(
→ 42).
2)
Relay assignement can be reprogrammed for atmosphere switching
function via serial interfaces (
→ 31 and [1] or [2]).
WARNING
Incorrect connection, incorrect polarity or inadmissible supply
voltages can damage the gauge.
