Method for reducing electronic balance error

Why the electronic balance will find errors in the data when it is used. This is because the electronic balance has not been calibrated for a long time, and some users think that the balance can be directly weighed by the zero position. (It should be pointed out that the electronic balance starts to display zero point. It cannot be said that the accuracy of the balance weighing data meets the test standard, and only the balance zero stability is qualified. Because it is necessary to consider the other technology when measuring whether a balance is qualified or not. Compliance of indicators ) . This is not the case. Due to long storage times, positional movements, environmental changes or for accurate measurements, the balance should generally be calibrated prior to use.

The electronic balance calibration method is divided into internal calibration and external calibration.

If you do not read the instructions carefully before use, it is easy to ignore the "calibration " operation , resulting in a large weighing error. How to externally calibrate the balance. Method: Press the CAL button when the CAL- appears on the display , the display will appear CAL-100, where “ 100” is the flashing code, indicating that the calibration weight requires a standard weight of 100g . At this point, the " 100g" calibration weight is placed on the weighing plate, and the display will appear "--" waiting state. After a long time, the display will appear 100.000g , and the calibration weight will be taken. The display should appear 0.000g . If it is not zero, then clear it again and repeat the above calibration operation. ( Note: In order to get accurate calibration results, it is best to repeat the above calibration steps twice. The method is as follows : the balance is set to zero, then keep pressing the “ CAL” button until CALint appears. The following conditions will show the balance when calibrating. Zero internal calibration weight Loading balance Balance rechecking zero balance report Calibration process Balance report Calibration completed Balance automatically returns to weighing state Some people think that the heavier the object weighed within the range of the electronic balance, the more damage it will damage the balance. This understanding is not completely correct. The maximum safe load of a general weighing instrument is the maximum static load that it can withstand without causing permanent changes in its metering performance. The principle of electromagnetic force automatic compensation circuit, when the weighing pan is loaded ( be careful not to exceed the weighing range), the electromagnetic force will balance the scales back to their original position, the electromagnetic force and gravity of the object is called equilibrium, as long as within the allowable range weighing affect the size of the balance is very small It does not affect the accuracy of the electronic balance due to long-term weighing.
