how to recalibrate a scale
I have a Detecto 1001-TBKG (8kg) scale that seems to have gone out of balance. It zeros out, with no weights and the poise at zero. But when I place a 500 gr. counter weight on the left plate and slide the poise all the way to 500 gr. on the right, the scale is off balance, with the left lower than the right. I've tried some of the other counter weights, placing the 1 kg. woth the 500 gr on the right plate and sliding the poise all the way to the 500 gr point, and placed a 2 k weight on the left. Off balance.Could it be the poise is off? How could that even be? Is this a calibration issue? I have no clue how to recalibrate this. The owner's manual is not helpfull at all. It's mostly a parts list. Actually, it's only a parts list. Any help on what to do would be great.
