Hi Dave, if you do go for a charge master, I suggest you run it from a battery. I ran a test once after I scored a lab scale for a good price, over time the charge master loads varied by up to .25 of a grain, even though they had been dispensed and trickled to the target weight, you could see the .25gn variation in a sine wave on the test weighed charges. Running on a battery brought the weights back to +/- .1gn

Just pay attention when you are setting up the battery and don’t reverse polarity on the battery terminals...chargemasters do not have reverse polarity protection....don’t ask me how I know this...I just know...

Cheers

Dave
