Disney, good catch on the calibration of scales. I've worked for a veterinarian for 6 years and we've never had our scales calibrated. However, when I worked at a bulk ag fertilizer dealer, the state calibrated our scale annually.
I've weighed at home with all my clothes on, gone to work, no eating/drinking and the scale at work 15 minutes later, is always heavier than my scale at home.
I prefer digital, you can get a decent one at Wal-Mart for $20.
PICK ONE! And that will be your official scale.
