Thread: Lyman 1200 dbs3 powder scales

Anyone use these scales?
I have some here that were given to me but im having issues zeroing the scales.
The instructions say to push zero to get a 0.0 reading then hold down zero until cal 20 shows then place the 20g weight on and press zero again, when you take the weight off it is meant to give a weight reading of -306gns but this keeps coming up with -183gns.

Anyone have any ideas.
