Electronic Scales

[ar10]

Why do you have it plugged into a UPS and/or turn it on 10 minutes ahead of time? Mine counts down from 10 (seconds) and is ready to go. I had heard other scales required long warmups, which is why I bought the Chargemaster.

There's a couple of reasons. On my Lyman it states to leave it 24hrs before using it. The better UPS units have line conditioning that stabilizes the voltage. Based on what I've read the electronic scales are extremely sensitive to fluctuations of in line current, even minor changes. I have mine plugged into a higher end surge protector that helps. I know that regular house voltage does vary quite a bit,from 100 to 140. At least that's what the electric provider told me when I was doing a lot computer installations.
