Hi, All optical probes don't…

Hi,

All optical probes don't work with EMH meters and I believe that it the problem in your case. Ask what optical probe you should use from the EMH.

Try to select "Use Maximum Baud Rate" and use 300.

In your next reply your meter is sending data using IEC protocol and not DLMS.

BR,
Mikko
