Help about a battery dial expression

Hi to all
I would use this battery dialAnnotazione%202020-02-20%20121038%20A
Is it correct the formula (-250-(#BLN#*2.5))
that i think to use? Or there is some correction to do?
Thanks for any help
Cheers

You would need to use
(210-(-#BLN#*3.0))

to make that dial work ok
