Hello Scott carpenter,

If you program menu 1–, please ignore menu 3–. They both are battery specificatin setting. Meter only save the last setting. Menu 3– is custom setting, you have to set minmum and maximum battery voltage.

Assume you set alaram value as 12v and enable this feature, when battery voltage reaches 12v, buzzer will sound.

Best regards.

Hello B Smith,

We think it should be this item, https://www.amazon.com/dp/B07B4B2X35?ref=myi_title_dp

Does the electronic brake  offer stable DC voltage?  If it can, that should be no problem.

Best regards.

Hello

To confirm the problem quickly, we hope to get more details by video. Would you like to show all of issue you have?

And negative current doesn’t mean  it is discharging current.  May I know if the  current follws the arrow on current transformer?

Best regards,

Hello Christophe j louine,

AH and FU setting are necessary, please program these two menus as per actual situation.

Assume battery rated capacity is 120ah, just set AH value as 100ah.

FU is regarding the maximum voltage  when battery is full charged. When  battery voltage reaches the level, battery icon will be full  automatically.

Notice: After finish setting, it will not show correct battery capacity at once. Please fully charge battery firstly, the charging current must flow through current sensor.

Best regards.
