Measuring a single ended input voltage
referenced to a split supply, i.e. the input
voltage and the meter's power supply
share the same 0V rail. Ensure solder link
LCOM is open.

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.
3.0 to 7.5V Meter Power Supply
Measuring a single ended input voltage
referenced to supply, i.e. the input
voltage and the meter's power supply
share the same 0V rail. Ensure solder
link LCOM is open.
