Does anyone know if / how you can calibrate the voltage shown on the Jeanneau DC LCD display (2006 DS)? It’s showing about 0.2V below the true battery voltage and I’d like to correct it. I’ve tried the menu but the options seem really limited (language, alarms on/off etc) without knowing some secret key press combination to open up more options?

I don’t think there is a way to adjust it on the board.
Mine was reading high and triggering the alarm. I put a diode in the house battery input line and it dropped the voltage enough to fix it. Making it read higher is probably harder to do.
The circuit only measures voltages, so putting something in the domestic input positive line (which also powers the board) to ratio the voltage up sounds like the way. Suggest you talk to someone that really understands electronics.
See recent post titled “Scheiber panel”
Good luck.

The chances are that the missing 0.2V is simply down to the length of wire and / or several connections between the Panel an the battery. Are you measuring the difference behind the panel where the main DC incoming cables are ... or just looking at a multimeter reading at the battery terminals? and comparing that to the boat Panel display? |

Pagoda54 makes a very good point. Connection loss is a possible cause that should be checked first. I checked the voltage directly at the house batteries and at the back of the circuit board on the panel and in my case the readings were exactly the same. (It was the panel that was reading high).

I’m aware that the Jeanneau panel meter is suffering from loss between the batteries and meter but just wanting to recalibrate if possible to offset that loss. It’s not a biggie because I also have an accurate DCSM meter at the chart table that has been calibrated to true battery voltage so I can get trusted readings from that - I was just hoping to align the Jeanneau panel meter with that if easy. But not important!

On the back of my analog voltmeter gauge is a small screw which allows you to adjust the voltage displayed so that it matches the battery voltage, but this is 2001 technology....

I have a Victron 712 battery monitor, and have confirmed its readings with a DMM on numerous occasions. The Scheiber panel says battery voltage is 14.1 (alternator charging) and alarms. The Victron says 13.8. The Scheiber panel says 11.8 and alarms. The Victron says 12.2. Ok, I get the latter, IR drop in the cables and connections. But the former, the high reading? Has anyone found a schematic for the Scheiber panel? Thanks, Geoff |
