SCALING
Two resistors Ra and Rb may be
used to alter the full scale reading
(FSR) of the meter - see table. Cut
the PCB track across Ra before
fitting Ra. The meter will have to
be re-calibrated by adjusting the
calibration potentiometer on the
rear of the module.
*Ensure that Ra is rated for high voltage use.
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.
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.
Ensure Jumper link J1 is fitted.
Ensure Jumper link J2 is not fitted.
Must use external scaling resistors (Do not cut track across Ra).
