After reading what I posted I can understand why it was confusing - my fingers didn't type what my brain was saying
When I plugged the Mk II lead into the radio, turned the radio on, and the antenna was down - the needle read all the way to the left. Raising the antenna made the needle move. I thought that was strange. Anyway, I'm charging the radio and receiver batteries tonight and will test tomorrow.
My transmitters have built in digital meters so I have no need to check them with an ESV. Many TX also have a protection diode in the charging circuit which will make it impossible to get ESV readings through the charge jack or at best an inaccurate one. You can expect a 0.7 volt bias drop across the diode itself. TX batteries are best checked out of the transmitter.
