It needs to be rebooted.
This question will be difficult to respond to, I
know because you can't see the scale, but I thought I'd give asking for
help a try.
I have an old, mechanical Ohaus 5.0.5-10
scale. It is in new condition - I use it to measure photographic
chemicals.
It's sat around on a table for quite a while since
I've gone digital and now, no matter what I do to it, I can't get it to
zero out. I've tried turning the wheel to raise and lower it. I've
moved the weights, etc., etc.
There is hardly anything to this scale - what can
be preventing it from zeroing out?
