@audphile1 you got screwed somehow, or it simply needed re-calibration,
I’ll double check mine, I used it for two cartridges earlier today, just listened with a friend for a few hours, Shure V15VxMR at 1.02 g and AT160ML at 1.22 g, both sounded terrific.
When I replace the batteries, I have checked it in the past with the weight they include to calibrate it, it shows 5.0g every time I check.

I’ve still got my Shure balance beam type, I can double check it.
