Suzuki SMG4 gauge inversion

[PhBST]

Hello
I bought a boat equipped with a Suzuki multifunction gauge. When I add fuel to the tank, the gauge tends to decrease rather than increase. I contacted the dealer to find out what I should do, and they told me the problem was related to the gauge's configuration. Despite my research, I couldn't find the information. It would be helpful if you could explain to me which menu I can use to change the direction of the fuel gauge.
Thank you for your advice.
Have a nice day.

Is it this gauge?

It sounds like you need to change the setting for the fuel sender from US to Europe or vice versa. The resistances are reversed on the senders. European: Full 190 ohms, Empty 0 ohms. US Full 30 ohms, Empty 240 ohms. If you have a SMG4, go into Menu, then select Tank Calibration.
