Thread: Chargemaster Lite Changing Zero

The pan weight on my chargemaster starts at 81gn. I calibrate the scale, zero it to the empty pan and start loading. Over the duration of say 40 rounds the weight of the pan slowly drops. For example after the first 5 rounds it might now read -80.9gn when I lift the pan off then after another 5-10 rounds it will be at -80.8gn and so on so forth until I got to -80.5gn after 40 rounds.

This is seen when I lift the pan with powder off the scale and it goes into the negative. The scale always returns to zero when the pan goes back on empty. Whenever it changes I re zero the pan and re calibrate the scale and keep loading but it doesn’t change that the weight of the pan has apparently drifted. I’m wondering if it’s a heat/warmth thing as the machine gets warmer from use?

Anyone seen this?
