Regarding the calibration method of electronic scales (be sure to carefully read the instructions before use), during the calibration (testing), we found that the balance needs to be calibrated*measurementThere is a large error during testing, and the reason for this is that a considerable number of instruments have not been calibrated for a long period of time, and it is believed that the balance can be directly weighed by displaying zero position. (It should be pointed out that when an electronic balance is turned on and displays zero, it does not indicate that the accuracy of the data weighed by the balance meets the testing standards, but only indicates that the stability of the zero position of the balance is qualified. This is because it measures whether a balance is qualified or not.),We also need to consider the compliance of other technical indicators comprehensively. Due to prolonged storage time, relocation, environmental changes, or to obtain accurate measurements, the balance should generally be calibrated before use. There are two types of calibration methods: internal calibration and external calibration. Produced by G&G Changshu Shuangjie Testing Instrument FactoryThe "JJ223BC" and other series of electronic averages have calibration devices. If the instruction manual is not carefully read before use, it is easy to overlook the "calibration" operation, resulting in significant weighing errors. Explain how to perform external calibration on the balance. Method: Press the CAL button lightly when CAL - appears on the monitor, release it, and the monitor will display CAL-100. "100" is a flashing code, indicating that a 100g standard weight is required for calibration. At this point, place the prepared "100g" calibration weight on the weighing plate, and the display will show "wait"stateAfter a long period of time, the display shows 100.000g. Take the calibration weight and the display should show 0.000g. If it is not zero, reset it again and repeat the above calibration operation (note: to obtain accurate calibration results, repeat the above calibration operation steps twice). Taking the JJ1023BF series electronic balance produced by G&G Shuangjie Testing Instrument Factory as an example, explain how to calibrate the balance. The method is as follows: set the balance to zero position, then continuously press and hold the "CAL" button until CAL int appears. The following situations will be displayed when calibrating: zero setting of the balance, completion of internal calibration weight loading, rechecking of the zero position of the balance, report of calibration process, report of calibration completion, and automatic return of the balance to weighing state. 1. Some people believe that the heavier the object weighed within the range of an electronic balance, the greater the damage to the balance. This understanding is incorrect. generalweighing instrumentA large safe load is a large static load that it can withstand without causing long-term changes in its metrological performance. Due to the use of electromagnetic force automatic in electronic scalescompensationCircuit principle, whenscale panWhen loading (be careful not to exceed the weighing range), the electromagnetic force will push the scale back to its original equilibrium position, balancing the electromagnetic force with the weight of the object being weighed. As long as the weighing size is within the allowable range, the impact on the balance is minimal and will not affect the accuracy of the electronic balance due to long-term weighing.
