I hope someone may know of a solution, otherwise a may have to send it in. I went to load for a mid range match. The scale stays plugged in, but turned off. When I turned the scale on, it started doing some major variation. I tried the tare button many times, but it wouldn't zero. After about 12 tries it zeroed, but gave me strange weight readings. 142 SMK's were coming up at 195 gn. my brass that weighs 195 gn were coming up at 225 gn. I tried to calibrate with the supplied 20 g weight. After going through the process several times I kept getting the same results. The check weight after calibration was reweighed and comes up at 20.5 g each time. Has anyone had issues like this before?
