There are many problems that cause the zero point of weight electronic scales to be unstable. From the perspective of internal factors, they are mainly reflected in the following points:
In order to solve the problem of unstable zero point of electronic weighing scales, it is necessary to choose high-quality sensors, which will inevitably produce measurement errors. The sensor automatically adjusts after being stressed to ensure good impact resistance and tendency force. Therefore, it is necessary to ensure that the sensor is installed securely and to protect the leads to avoid friction problems with the load-bearing body and to provide reliable protection devices. Therefore, we should try our best to choose a load cell with moderate accuracy and large output resistance to effectively solve the problem of unstable zero point of the electronic weighing scale and control the error within a reasonable range.
When using an electronic weighing scale to weigh objects, the main thing is that the electronic weighing scale's table weighing body is in direct contact with the object and kept at the same level to avoid the table weighing body being deformed under different loads and increasing the weighing error to a certain extent. Therefore, choose a weighing body with strong rigidity and good strength to avoid weighing body deformation and effectively solve the problem of zero point instability of electronic weighing scales.
In order to ensure the anti-interference performance of the display, the power supply voltage stabilizing circuit is required to be stable and the conversion rate meets actual requirements. It can be learned from long-term practice that there are various factors that cause the zero point of electronic weighing scales to be unstable, and a key problem is caused by unstable power supply, which requires great attention.
If the weighing scale electric is placed in an uneven position, especially on an unstable ground, it will easily tilt when bearing weight, and the weighing result will be far from the actual value. For example, the foundation of a heavy weighing object is not strong, and the foundation may be deformed due to the influence of temperature. The sensor is unevenly stressed, the load-bearing results are inaccurate, and the zero point of the electronic weighing scale is unstable.
External environment, such as windy weather, will affect the normal use of electronic weighing scales. Especially when weighing outdoors, it is inevitable to encounter such problems. How to effectively solve the problem of unstable zero point of electronic weighing scales can be effectively solved by changing the position or installing a windproof cover.
The accumulation of dust on the weighing body of the electronic weighing scale, if not cleaned in time, will produce an upward force. In addition, there will be water accumulation in the dust, or the sensor microcircuit will be corroded in a humid environment, which will affect the accuracy of the weighing results of the electronic weighing scale and cause weighing problems. The zero point of heavy weighing scale electric is unstable. Under normal circumstances, staff are required to regularly maintain and maintain electronic weighing scales to reduce malfunctions, keep electronic weighing scales clean, and avoid damage to electronic weighing scale sensors.
The grounding problem of electronic weighing scales is rarely taken seriously, and this problem has a greater impact on the accuracy of electronic weighing scales. Under normal circumstances, the grounding resistance of electronic weighing scales does not exceed 4Ω, and is mainly independent ground level. If it is an electronic weighing scale powered by mains power, you should pay close attention to the grounding problem of the electronic weighing scale body and power supply, and handle it uniformly to avoid the problem of unstable zero point of the electronic weighing scale.
