PIN FUNCTIONS
1. V+
2. 0V
3. COM Ground for analogue section of A/D converter.
4. IH
5. IL
6. DP1
7. DP2
8. DP3
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).

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.
Positive measuring input.
Negative measuring input.
Connect to 0V to display DP1 (199.9).
Connect to 0V to display DP2 (19.99).
