I bought a DPS3 some time ago. The first time I set it up and used it, it functioned fine. The second time I tried to use it, it wouldn't repeat, and wouldn't move to the next charge weight I had programmed in. I've set it aside and gone back to my old Ohaus balance beam. I need to call the factory and see what they want to do about it. It may be a simple fix, but needless to say, I'm not a happy camper over it.
