SCALING
Two resistors Ra and Rb
may be used to alter the
full scale reading (FSR) of
the meter - see table. The
meter will have to be re-
calibrated by adjusting the
calibration potentiometer
on the rear of the module.
APPLICATIONS
Do not connect more than one meter to the same power supply
if the meters cannot use the same signal ground. Taking any
input beyond the power supply rails will damage the meter.
±200mV
±200mV
Measuring an input voltage referenced to a floating supply,
i.e. the input voltage and the meter's power supply are
isolated from each other.
Measuring a single ended input referenced to supply, i.e.
the input voltage and the meter's power supply share the
same 0V rail.
