I bought a Lyman 1200 DPS II in February of 2005. This scale has always performed flawlessly for me throwing charges within +/- .10 grain. Then it recently started throwing charges that varied by 8/10 grain when checked against my old Ohaus 10-10. I called Lyman about the problem and was told it was likely a static issue and was prescribed the following fix.

1. Saturate a towel with Windex. I used paper towels and the bottle I bought at the store reads Windex Original with ammonia-D

2. Wipe down everything on the scale inside and out without dis-assembling anything and let the unit air-dry.

3. Do this a total of 3 times.

I did exactly what they said to do and I did it it exactly how they said to do it. The procedure immediately solved the issue and the scale is back to working the way it always had. Just putting this post out there because I remember more than a few members were having the same problem with their electronic measures and scales.

Thanks, cvc - have one just like it. If it starts going haywire, will know how to fix it.

I'd be interested to hear the "WHY" part of this from the same guy at Lyman.

The Windex part is interesting enough. The three times part is odd though. Makes me wonder if two or four times WOULD NOT work?

Good post.

It seems to me clear it's a static electricity issue but, like Cheezy, I'm wondering why "3" times. Maybe they're figuring it ensures you got it completely covered. Interesting. Maybe that fix would work on my cheap little $30 Hornady's?

Find an old computer UPS (the kind with the battery in them, not the little 'spike strips). Plug your scale into that. It will clean up the power enough to enhance reliability.

An old UPS is not worth much once they don't have enough juice to run a computer, but it should handle a scale nicely for a long time. I reload under florescent lights in the garage and had no end of trouble till I did that (the lights are on the same circuit as the outlets so there was no escaping the interference).

You never know what else in the house might be plugged into the same circuit, or what the quality of the power is. Laptop? Surprises me to see that on the list but who knows..... I would not expect a laptop to draw enough power or generate enough interference. But, surely they've learned this the hard way so I'd trust the recommendation.

Cheezy,

The trick is that Windex is not rinsed off, so it does what any anti-static cleaner or soap film does, leaving a thin ionizable coating behind that bleeds the charge off at the corners. The triple application is probably just to get a coating that's heavy enough, since Windex is designed to be thin and invisible. Probably cleans airborne oil deposits and other crud off the dispenser better than my anti-stat CRT cleaner, though.

I've had my Dillon "D-terminator" scale since 1995-1996 or so, I believe. Maybe 1997. Anyway, it's worked just fine and the only trouble I ever had was when it was plugged into a circuit that had florescent lights. After I put the scale on an old computer UPS that problem went away.

Still have a balance beam scale for backup and I always use check weights with either one.
