Hi,
I have tried for an hour to get along with the instruction but I get displays different settings then indicated in the instruction.
I have the meter in a electric car to measure the battery which has 120Ah and 72V.
When I press the rectangle to set, the display shows things like: FU3, AH2…. How can I set the full capacity to 120Ah? I also can only enter 2 digits…
Merci
