SCALING
Two resistors Ra and Rb
may be used to alter the
full scale reading (FSR) of
the meter - see table. The
track across Ra must be cut
for on-board scaling. 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.
5V supply operation
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 jumper link J1 is not fitted.
Ensure jumper link J2 is not fitted.
9V supply operation
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 jumper link J1 is not fitted.
Ensure jumper link J2 is fitted.
