The use of electronic scales has been used in various industries. It not only has high-precision metering, but also is versatile and versatile. Electronic scales are divided into two categories: automatic scales and non-automatic scales. Non-automatic electronic scales are commonly used in the market. It is mainly used for trade settlement, and it is also the electronic weighing instrument with the most contact with the masses. For example, electronic scales, electronic platform scales and electronic truck scales commonly used in it; automatic weighing instruments are generally more common in industrial and mining enterprises' batching scales and quantitative packaging scales. First, the choices: 1 According to the alleged items: items with high economic value should be selected with high precision scales (it is said that gold should choose a balance of 0.1mg, and the egg can be selected with a 1/3000 precision price scale). .2 According to the weighing used: If it is often called tens of kilograms, you can choose a 100 kg scale (often weigh the weight should be the best median of the maximum weighing). Too small a selection will damage the sensor and cause unnecessary economic loss; too large selection will make the weighing inaccurate and affect the accuracy of the measurement. 3. According to the function of use: If you need to calculate the quantity of the item, you can select the counter (table/case) scale; the quantity of the packaged items can be selected as the weight (table/case) scale. Second, the basic knowledge of electronic scales: 1. Maximum weighing (range): Your regular weighing should be best around 2/3 of the maximum weighing selected; 2. Table size: the size of the object should not exceed the range of the table; 3. Display accuracy: the display accuracy is less than the detection error value of the item; 4. Accuracy: The accuracy scale of the scales currently on the market is (III) scales, the firm indexing is generally 3000 divisions, and the minimum division value varies from 0.001g to 50kg depending on the size of the weighing, according to requirements and Economic situation choice; 5. Use function: weight / peel / zero, price / accumulation, count / accumulation, percentage / average, upper and lower limit alarm, computer output interface, print output interface, display output interface, storage / memory function, unit of measurement Choice, wireless remote control / digital transmission. Power supply mode: AC, DC, AC/DC, and choose according to actual needs; Third, important choices: 1. Use an environment with high dust, humidity, and rain. Choose an electronic scale with high protection level. 2. Use a strong magnetic field in the environment, and choose an electronic scale product with special protection when the large power equipment interferes. 3 Select a regular manufacturer's product with a production license, and have: instruction manual, certificate, and warranty card. Fourth, general testing; 1. The digital display is stable (no hop count) under the state of the electronic scale empty scale and the maximum weighing state; 2. Use 1/3 of the maximum weight (or a weight close to this value) to place the test point numbers in the range of 1/4 of the weighing platform (4 points equally divided). 3. If conditions permit, take the standard weight of the maximum weighing on the scale surface to test its accuracy; 4. Take the standard weight close to the maximum weighing (or a weight close to this value) and load it 3 times repeatedly to test whether the numbers are consistent; 5. Press each function key to test whether each function key is in good contact and can achieve the purpose. 6. Charging test: Pay attention to whether the power supply is 220V. Plug in the charging circuit should be able to supply power to the electronic scale and charge the battery.
