I have tried a setup as you suggested. For the power supply I used a 12V car battery. I wired in a 200 ohm resistor which would limit current to 60mA if there was no internal resistance in the meter. Bridging the meter connections with a wire this produced a step to 12V on the scope. Bridging the connections with a 2000 ohm resistor produced a 1.2V step on the scope. Perhaps the 200 ohm resistor is a little conservative but I do not want to damage the meter.
I tested this setup on both the active import and active export settings and still no pulses.
I am starting to think it may be a setup issue as you suggested. I am a little short on ideas of what to try next.
The system runs at 2kW export. What pulse frequency and duration do you suggest. I have been trying 500 pulses/kWh and 100 msec pulses.
I have attached an image of the connections to the meter showing the pins I have chosen,
Thanks Alan
