Note:
A negative supply is generated internally and mirrors the positive supply. For example: if V+ is +5V, then
the internally generated V- is -5V. When measuring with the input referenced to the same supply rail as
that of the panel meter, then the limitations on the input range are (V- + 1.5V) to (V+ - 1.5V).

Normally Open. Connects INLO to COM.
Normally Closed. Cut this link to disable the internal decimal point drive circuit and thereby
reduce the meter's current consumption.
Positive power supply to the meter.
0V power supply to the meter (3.0 to 7.5V meter power supply applications only).
Negative power supply to the meter (6.0 to 15.0V meter power supply applications only).
Connect to the meter's negative supply voltage to switch on the LED backlighting.
For meter supply voltages above 5V, add a series resistor Rs.
See Applications for suitable circuit diagrams.
Positive measuring input.
Connect to XDP to display DP1 (199.9).
Connect to XDP to display DP2 (19.99).
Connect to XDP to display DP3 (1.999).
Connect to pin 7, 8 or 9 to display required decimal point.
