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).
