How to calibrate a on-board wheel loader scale?

As a kind of weighing equipment, the loader electronic scale also needs to be adjusted. The convenience of the adjustment function is an important condition for selecting the loader electronic scale. Since different manufacturers have different efficiency adjustment functions, the efficiency adjustment function of PPM-LS300 loader electronic scale is mainly introduced in the following ways in this article.

Record the date in the empty bucket state and under heavy load

First, the data will be recorded automatically after three times lifting of any throttle in the empty bucket state , so does under heavy load .At the end , input the weight under heavy load. When the weighing error during actual measurement is small, the weight in the menu setting will be adjusted.

Use the sopporting software to automatically learn and collect thedata

Second,use the supporting software to automatically learn and collect thedata of the current empty bucket lifting and heavy haul lifting, and upgrade and store the system software. When the weighing error is small, the data can be fine tunedbyProfessional calibration personnel. The stability of weighing data is relatively long but the calibration cost is relatively high

Calibration weightby the throttle lifting speed value and empty bucket data

Third , record the throttle lifting speed value and empty bucket data When the empty bucket is lifted .Then confirm the heavy lift data when the heavy lift throttle speed value is the same with the empty bucket lift throttle speed value .Thatweight under heavy loadis the confirmedweight. When the weighing error in the actual measurement process is small, adjust it through the speed compensation function in the menu setting.

According to the field experience, the more throttle data recorded during calibration, the more obvious the difference between throttle sizes, and the more accurate the weighing. Because each operator steps on the accelerator in different ways during the actual loading process, the existence of multiple groups of data makes the operator weigh more accurately and the calibration cycle interval longer when the lifting accelerator is closer to a certain group of data. Therefore, when choosing the loader electronic scale, we should choose the loader electronic scale with more throttle data records and obvious throttle size differences.
