Last week we had to replace the head on a 40,000 pound scale. Used 2,000 and 1,000 pound weights. Calibration was a breeze, basically just a handful of button pushing steps (ain't microprocessors great?)
I noticed afterward that if I step on the scale the indication goes right up to my weight and goes right down to zero when I step off. When the forklift we used to place the weights goes on, the indication again goes right up to ~11,000 lbs. However, when the lift goes off the indication goes to -6 to -8 pounds, then slowly recovers to zero.
This deck is 20+ years old. Do load cells get 'tired'?
