Ok stupid draw if done. Back to reality.
I have been using my chargemaster 1500 for years. A month or two ago I was calibrating it. You have two 50 grain brass weights that you put on the scale one, and then the other. So after it calibrates that 100 grains I removed both weights. I placed the 50 grain one back on the scale and it read 77 grains

I zero the scale and then placed the same weight back on and it read the same.. How is this possible. I looked at the directions to see if there was some kind of reset but didn't find one. Went through the entire calibrate procedure twice more and same results. What am I missing?
