i used a Sartorius GD 503 for 4 years and it worked perfectly with no drift when weighing powder charges. Unfortunately it failed and needed to be replaced. I bought its recommended replacement the Entris 64. Here's the problem. The Entris weighs in .002 grains where the GD 503 weighed in .005 gn. My new scale placed the exact same place will drift and not stabalize into a weight. I can even leave the room and the displayed weight will still be changing. Let me give an example. A kernel of weighs approx .020. When tarred and calibrated my scale will vary from about .016 to .034 and keeps floating for a single kernel. How do others Entris behave? Have you changed any settings other than the weight unit? Maybe I'm spoiled but my old scale would stabilize the display within a second or two. I could fly through the powder process, now it is painfully slow. If I can' solve this I will try to send it back.
