Is it repeatable?In reality I dont care what the exact weight is so long as its repeating wrongly and the desired effect occurs out on the paper.jim
I have a penny, three scale pans, several scale weights and a couple cases full of powder setting near my scale.
Twice now I've dumped a "scale check case" full of powder into the pan and instead of my magical number of 40.04gr I saw 40.02 and once even 39.99......... (I'm checking the powder too...for hygroscopicity)
In the one case I carefully inverted the case and flicked it with my fingernail and a recalcitrant kernel of H4350 tumbled out.
The other time it was three kernels.
I leave my scale on for months, it sets under it's cover reading 00.00
I sometimes turn it off and on day by day and it reads 00.00
In my case, once I took control of the environment the scale went to rock solid repeatable.
