Digital Scales - Any good?

[Rocky Raab]

Yup, something wrong there. You seem to be losing calibration somehow.

Was the scale properly warmed up? Some say a 20-minute warmup is required.

Did you get any warning messages? Mine flashes when it loses calibration or drifts.

Have you checked for electrical interference? Mine would go off when the clothes dryer started or my (former) neighbor would transmit on his HAM radio, Even a fluorescent light going on nearby can throw them for a loop. Hrad to track down sometimes, but is often the cause.
