But another colleague of mine mentioned that the B50 showing 25 volts to earth is half wave rectification, I am confused as how that relates if at all.This is not strictly relevant to the forum, but it is interesting and I am sure we can make a learning point of it! Can you post a picture of the item?
Any clarification would be greatly received.
