Reference voltage, VREF
The IQAN module is internally equipped with a voltage regulator to generate the
reference voltage
VREF
. The standard reference voltage will feed different kinds of
sensors and potentiometers.

It is strongly recommended to use the module’s
-VREF
and
+VREF
to all sensors and
potentiometers that are connected to the module inputs. This will reduce bad
measurement based on potential fault (i.e. different ground points for other supplies in
relation to the IQAN module ground, -BAT).
