DFE load cell float at Tagline

Bad load cells only revealed themselves after trying to calibrate at several different weights. Using a flat head screwdriver to pry on load cell roller got weight feedback and it would return to zero but that didn't mean they were ok. Need to try a known weight calibration and test with other measured weights to make sure feedback is accurate. Load cell resistance also measured ok, but must have had some load cell beam cracks. They have a U shaped connector and I've had both break before where unit can come apart fully but if only one of the two beams is cracked, much harder to troubleshoot.
