With the continuous growth of the social economy, the development and improvement of science and technology, an increasing number of cutting-edge technologies have emerged. Relying on computer technology, electrical technology, and sensor technology, they are integrated into electronic weighing scales and widely used in various industries due to their unique advantages. Electronic scales are used to solve the problem of unstable zero point, stressing the importance of zero point display, reducing measurement errors, improving deficiencies, enhancing measurement accuracy, and avoiding losses caused by objective factors.
The appearance of the problem of unstable zero point of electronic scales is mostly due to sensor failure. Replacing the sensor is a way to solve such problems to ensure the normal display of the zero point value. Replacing the sensor is relatively complex, time-consuming, and costly, so repairing the sensor is usually chosen to solve the problem of unstable zero point of electronic weighing scales. Faced with the growing demand, appropriate measures should be taken to solve the sensor failure and replace the resistors on the circuit board in a timely manner. At the same time, it can ensure the balance at the measurement bridge, and the output voltage of the bridge is zero without load. It should be noted that due to the frequent use of weighing electronic scales, inevitably, they are subjected to the pressure of the weighed objects. Excessive pressure can cause a larger load, may deform the sensor, and affect the accuracy of the final weighing result.
If the sensor of the electronic weighing scale is unstable at zero point and the voltage signal output is too high, a resistor can be connected in parallel to reduce the positive signal output voltage, keep the circuit balanced, and ensure the normal use of the weighing electronic scale. In the application of electronic scales, it is not strict for the sensor to output zero under no load condition. When a resistor is connected in parallel, it is only necessary to ensure that the resistance value meets the actual needs. During the maintenance of electronic scales, mainly rely on electrical instrument testing of electronic scales. Even if the accurate measurement of sensor bridge parameters cannot be obtained, the maintenance work of electronic scales can still be successfully completed to ensure the normal use of the sensor.
In conclusion, the problem of unstable zero point of electronic scales is common, with significant errors that inevitably affect the accuracy of the final weighing result. It is necessary to choose the appropriate repair method based on the actual situation, whether to repair or replace the sensor, in order to timely solve the fault and ensure the normal use of the electronic scale.
