How to calibrate electronic scales
Electronic scales are commonly used weighing tools in modern commerce and industry, and their accuracy is directly related to trade fairness and production efficiency. Recently, the topic of electronic scale calibration has become increasingly popular in major forums and social platforms, especially small and medium-sized business owners and individual merchants. This article will introduce the calibration method of electronic platform scales in detail and provide structured data to help users quickly grasp the key points of operation.
1. The importance of electronic scale calibration
Electronic scales may weigh inaccurately after being used for a long time or subjected to external impact. Calibration is a critical step in ensuring that its measurements are accurate. Here are some common usage scenarios that illustrate the importance of calibration:
| Usage scenarios | Calibration Necessity |
|---|---|
| commercial trade | Avoid disputes caused by weighing errors |
| industrial production | Ensure accurate ratio of raw materials |
| laboratory | Ensure the reliability of experimental data |
2. Steps for calibration of electronic scales
Calibrating electronic scales is usually divided into two methods: internal calibration and external calibration. The following are the specific steps:
1. Internal calibration (automatic calibration)
Internal calibration is performed through the built-in calibration program of the electronic scale, which is suitable for models with automatic calibration function.
| step | Operating Instructions |
|---|---|
| 1 | Place the electronic scale on a level and stable surface |
| 2 | After powering on, press and hold the "Calibration" button to enter calibration mode. |
| 3 | Follow the on-screen prompts to place the standard weight |
| 4 | Wait for the calibration to be completed and the screen will display "PASS" |
2. External calibration (manual calibration)
External calibration is suitable for electronic scales without automatic calibration function, which requires users to manually enter calibration parameters.
| step | Operating Instructions |
|---|---|
| 1 | Prepare standard weights of known weight |
| 2 | Place the weight in the center of the electronic scale |
| 3 | Record weighing results and calculate errors |
| 4 | Correct the error by adjusting the potentiometer or entering the calibration coefficient |
3. Calibration precautions
When calibrating an electronic platform scale, you need to pay attention to the following points to ensure the accuracy of the calibration results:
| Things to note | illustrate |
|---|---|
| ambient temperature | Avoid calibrating in environments with large temperature fluctuations |
| Standard weight | Use certified standard weights |
| horizontal adjustment | Make sure the electronic scale is level |
| Regular calibration | It is recommended to calibrate every 3 months |
4. Frequently Asked Questions
The following are recent frequently asked questions and answers from netizens about the calibration of electronic scales:
| question | answer |
|---|---|
| Weighing still inaccurate after calibration | Check whether the sensor is damaged or whether the table is level |
| What to do if there is no standard weight | Substitutes of known weight may be used (e.g. unopened beverages) |
| Calibration password forgotten | Contact the manufacturer for default password or reset method |
5. Summary
Calibration of electronic scales is a key step to ensure accurate weighing. Whether it is for commercial or industrial use, it should be calibrated regularly. This article provides detailed steps for internal and external calibration, and lists precautions and FAQs, hoping to help users better maintain and use electronic scales. If you encounter a problem that cannot be solved, it is recommended to contact professional technicians or manufacturer after-sales service.
