LINDA ~ I am having a similar problem ... I was first weighed at the doctor's office, but it is hard to get appointments here just to get weighed in; so I thought I would get my own for at home for convenience; and, becuz many people feel that we should be more accountable.
I bought a digital that was on sale for $30.00. Well, shock of shocks, it said that I had suddenly gained 8-12 lbs (wasn't sure cuz it kept changing). I was devastated, cuz I thought I had gained a pile of weight, but didn't know why; but then later on, I found out that I hadn't gained any at all: it was the new scale.
Crazy or what?
Every time I step on it, it changes its mind what I weigh; and you only have so many seconds to get on it right, or it reads ' ERROR '. If you move even in the slightest way, it goes up; if you touch anything, it goes down. I have a water-weight fluctuation of 3-5 lbs (on average about 4 lbs) before and after menses. I don't ever remember having a problem like this with any other type of scale in the past.
I guess that I will just have to live with it for now; cuz I hate wasting the money that I spent on it; but down the road, I think that I am going to buy an analogue one. I never cared about .1, .2, or .4 of anything; I just want to know approximately how much I weigh! Thanx for letting me vent ...
