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).

Positive power supply to the meter and LED backlighting.
0V power supply to the meter.
Negative power supply to the LED backlighting.
Positive measuring input.
Negative measuring input.
Connect to V+ to display DP1 (199.9).
Connect to V+ to display DP2 (19.99).
Connect to V+ to display DP3 (1.999).
Negative power supply to the meter.
Ground for the analogue section of the A/D converter.
It is actively held at 3.05V (nom.) below V+ and must not be allowed to sink excessive
current (>100 A) by, for instance, connecting to a higher voltage.
