A:

If it has only 2 wires, and you connected the red to + and the black to - then you could have a defect. Most likely you have it connected backwards. I would suggest you confirm the voltage and polarity with a Volt meter. If it reads more than 40 volts you may have destroyed it.

Q:
For the three wire 100v only: Do you have a wiring diagram? is 48 v too much as a operation voltage?

For the three wire 100v only: Do you have a wiring diagram? is 48 v too much as a operation voltage?

A:

There is now a wiring diagram as part of the listing. The 3 wire version with yellow lead requires a separate power source for the meter itself. That lead is used if the voltage to be measured is 28 volts.
