I bought one of these from WSS' closeout sale and have found it to be completely unuseable. I'm wondering how many others have had the same experience with this scale and if anyone found a way to get it to work. Here's what I've done and how it has performed. Set it up on the same solid, level base as my RCBS 5-0-5 (which works beautifully), there are no fans in the room, temp is very stable, tried turning off the lights, tried new batteries, waited over 15 mins for warm up. The scale drifts wildly all over. It will pass cal with its 10g weight but will not stay at any reading. It starts small, usually + or - 0.2 - 0.3 gr at first and will swing above and below zero. Then the number slowly groes to as much as 3 grs for a total swing of 6 full grains. It does this at zero with pan, negative reading without pan and with weight in the pan. It will not stabalize no matter how long I wait. Sometimes it will re zero and hold for maybe 30 seconds tops then off it goes swinging all over again. I sent it to Korth for warranty and received a new one that does the exact same thing. But all I see on the internet is good reviews. What have your experiences been with this scale?
