During static weighings for instance slowly filling a fertilizer soreader the displayed weight is usually lower than the true weight of the load because of tensions in the system Under higher loads the scale might not react smoothly to changes in weight When you have enough experience with your system you can add the missing weight If not you have to stop filling a bit earlier and clear the tensions in the system by moving after which the correct weight will be displayed Check without attached implement whether the scale displays the same weight on both sides Stand on the left and then the right side of the linkage If the difference is larger than 5 kg one of the load cells is malfunctioning or load cell AGRETO electronics GmbH page 28 AGRETO three point scale Suspension needs to be readjusted If this is the case please contact the manufacturer Check with implement attached whether the scale shows the same weight when the load is in the front and then in the back of the implement If this isn t the case the imbalance must be offset by changing the angle of the top link mounting brackets If the scale displays a higher weight in the back you must shift the two mounting parts slightly upwards You do not have to remove the scale Loosen the 4 internal nuts of the mounting screws and tap the bottom of the sliding mounting parts with a rubber hammer If you can t slide them any further you have to remove the sca

Make sure that there is no transfer of forces because a part of your implement touches the scale The implement can only be in contact with the scale through 3 attachment pins Make sure that the scale isn t attached too tightly on the side to your implement Check if there is still some space on both sides of the lower attachment points Consult chapter 6 of this manual Check whether the angle between scale and mounting brackets is exactly right The factory set calibration is only correct under an exact right angle and the position of the load doesn t influence the weighing result Consult chapter 6 of this manual Try to use the scale in a position that is as vertical as possible Use the top link brackets with either 130 mm or 160 mm hole spacing If this isn t possible the weighing indicator must be calibrated for the application A small deviation of a few degrees doesn t matter that much Calibrate the scale Follow the instructions in this manual chapter 7 10 Unsatisfactory weighing results can be caused by tensions in the scale s suspension The 3 attachment pins aren t supported by ball bearings and even when balls and or hooks are used tensions build up in the system due to load changes These tensions dissipate while driving or moving This is the reason why the scale and implement must be moved twice during the calibration process It also explains why the scale weighs more accurately during movement than during standstill
