Hello Ramon L Collazo,
Thanks for writing in.
As per your inforamtion, it shoud be 2001710003
Submenu 2 is for delayed shutdown. If you set delayed time, meter will turn off after that time.
If your 12v battery is leacd-acid type, please set P12v in submenu 1.
Submenu 3 is custom setting. Some battery specifications are not available in Submenu 1, then you can choose submenu 3.
You just need to set minimum voltage and maximum voltage for your battery. Hope that can help you.
Best regards
