This morning when checking what our ranges are on ZM4 and ZM5 PSAMS, we noticed that ZM5 wasn't working, plot,  strain gauge was reading ~ -1 to -1.3V in the whole 0V to 200V range. The issue looks like electronics and started Saturday afternoon when no one was working on it, plot attached. 

Ryan and I went to the chassis and checked the calibration box Daniel modifed was securely attached 91106, holding it tight to the chassis made no difference. We then pulled it and took it to Fil.
