Default mechanical zero on a small meter

After setting zero I moved my finger over the meter face first thing
in the morning and the needle moved up scale about 10 percent. I let
it sit on the bench for about 24 hours without touching it. When I
looked at it again it was back to zero. So the trick is to set it,
leave it for a day let it discharge, and then tweak it again. Clumsy
procedure but it works. Glad this is my own equipment and not a
customer repair job....Lenny


Nice workaround. So it is static. Is this NORMAL for a small panel
meter? We don't have much of a static problem on the left coast, so I
don't see much of that. I waved my hand around various small panel
meters around the shop. No deflection.
