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: ifV+is+5V, then
the internally generated V- is -5V. When measuring with the input referenced to the same supply rail as
that of the panelmeter, then the limitations on the inputrange are (V- + 1.5V)to (V+ - 1 .5V).
