where does the Cerbo/GX Touch draw its voltage reading from?

Hello, I have a customer with an issue and Im out of country right now. He installed his own multiplus, cerbo gx and touch 50.

When running a load on the multi. His voltage is 12.8 on the bmv712.(matches what is at the main bus bars) But 12.1-12.2 on the touch 50 .

What can cause this discrepancy?

Where does the touch 50 draw it's voltage reading from?

Thank you

Hi, Cerbo/GX touch draw their voltage reading from the bmv, by default.


and there is an option to prefer the multi.

See Settings -> System setup

Also in the manual.


success!

Thank you, then I'm really curious why almost any volt discrepancy between the blv and the touch50?

Hi, you need to check that setting and/or in the Device list on the GX Touch see which devices shows what reading.


and then in most cases its due to a bad connection, and thus voltage drop. So take a multi meter out and measure where the issue is.

Thats all I can advise so remotely I’m afraid, success!
