Hello, everyone. The meeting will answer your questions. Electronic scale shows how to eliminate lb, electronic scale shows what problem lb is, many people do not know, now let's take a look at it!

Answer:

1. Check the power supply part of the electronic scale and measure whether the charging voltage is correct. If the voltage is low, it should be charged in time.

2. If the charging has not been solved, it may be a battery problem and the battery needs to be replaced.

3. Instrument, scale, signal wire, junction box, sensor and so on are damaged. It could cause a malfunction. Observe each part carefully to ensure that the electronic scale is working properly.

4. Four elements of using electronic balance:

5. First, preheat ahead of time. Electronic balance usually needs to be preheated before use, and the preheating time of each balance is often different. Generally speaking, the higher the accuracy of the balance, the longer the preheating time, which can be preheated in accordance with the requirements of the balance manual, and can be extended if necessary (usually the lower the ambient temperature, the longer the preheating time); secondly, environmental conditions are also an important factor affecting the metering performance of the electronic balance. If there is no special temperature limit in the operating instructions of the electronic balance, the balance should work normally at a temperature of-10: 40. If a special temperature limit is specified, the balance should work under the specified temperature conditions, and the electronic balance also has requirements for ambient humidity, such as the relative humidity of the first-class balance does not exceed 80%. Third, grade status. Generally speaking, high-precision electronic balances are equipped with liquid level regulating devices and liquid level gauges. In use, the horizontal state of the balance should be checked frequently. In fact, some users often ignore the check of the horizontal state of the balance. The fourth is to calibrate at any time.

6. Related classification:

7. According to the accuracy of the electronic balance, it can be divided into the following categories: the maximum weight of the ultra-micro electronic balance is 2-5g, and its scale value is less than the power of (maximum) 10-6; the weighing value of the microbalance is generally 3-50g, and its fractional value is less than the power of (maximum) 10-5; the weighing value of the semi-microbalance is generally 20-100g, and its fractional value is less than the-fifth power of (maximum) 10. The maximum weight of this kind of balance is generally 100 to 200 grams, and its index value is less than 10 to the fifth power of the weight; the analytical balance is actually a kind of electronic analytical balance, which is the general name of constant balance, semi-micro balance, micro balance and ultra-micro balance. Precision electronic balance, such as electronic balance, is the general name of electronic balance with precision level.

This is the end of this article. I hope it will be helpful to all of you.
