CAUTION:
To prevent interfering signals caused by
the supply voltage, this input is isolated from the
supply voltage. Connect the signal line with the -
Signal to the analogue reference input.
ANLOGUE REFERENCE INPUT

If no isolation between measuring circuit and supply
voltage is necessary, connect pin 2 or 3 to this input
VOLTAGE INPUT
(Connect 7)
Analogue voltage input. Connect the signal line with
