Hoping someone can advise me whether this is fixable. I bought it used a few months ago, but the reading never changes. I've tapped it to no avail, and the needle will move correspondingly when I turn the calibration screw, but that's it. Is there anything I can do, or is it scrap brass?

Maybe contact Abbeon and see what they say...

What Ed said. I know that Abbeon does do service out of California because I used to send mine to them for calibration before I learned how to do it myself. If you want I can find their contact info for you?

Hesh, I'd appreciate that, thanks!

Here you go:

Abbeon Cal, Inc.
123 Gray Avenue
Santa Barbara, CA 93101-1809
USA

Phone: (805) 966-0810
(800) 922-0977
Fax: (805) 966-7659

open the back - there is a little screw for calibrating the hair - make sure it is not maxed out in any direction.
It should be set so the balance has equal travel in both directions.
After that you need to do a salt test to recalibrate.

Or just send it to Abbeon.
