I am not very satisfied with the display contrast
of my old trusty DMM254... Is there a way to increase
the contrast to make digits more dark in some way?
When I open the meter to change battery (I was thinking
battery is weak and this is the reason for contrast
change) I see multiple variable pots, I guess used to
calibrate this thing, and maybe to change LCD contrast.
I have no documentation and I do not want to mess it up.
Anybody here knows with pot is used to set the contrast?
What is the purpose of all other pots on its board?
