Precautions for the use of electronic balance

electronic balance is used to measure the mass of objects and is widely used in enterprises and laboratories. The utility model has the characteristics of simple structure, convenience and practicality, fast weighing speed, etc. At present, there are many kinds of electronic balances used in China, and then calculate the average value, whether domestic or imported; Whether it is large or small; Whether it is high precision or low precision, its basic construction principle is the same. How to correctly install, use and maintain the electronic balance and obtain correct weighing results is one of the effective methods to ensure product quality. In the field verification work, it is found that the balances of many enterprises are not installed, used and maintained as required, resulting in great deviation of measurement data, exceeding the maximum allowable error required by the verification regulation. In order to enable the staff engaged in the use of scales in the enterprise to obtain accurate weighing results, Martens, who extended the balance, said: "sometimes the source of recycled materials is also a big problem. Now, the problems that need to be paid attention to in the correct installation, use and maintenance of the electronic balance are analyzed as follows:

1. Cleaning requirements before installing the electronic balance

(1) first, remove the floating soil and other objects with a brush or deer skin.

(2) Wet silk cloth shall be used to remove dust in the weighing room or near the magnetic steel, and dust and dirt shall not fall into the magnetic steel, so as to cause the failure of the balance

(3) wipe the balance and components with a damp flannelette (solvent is not suitable)

(4) wipe the balance and its components with clean deer skin or silk cloth to ensure the cleanness of the balance

the results showed that 100 patients with soft prostheses were basically satisfied, of which 10 patients in the hard prosthesis control group felt more comfortable than the hard prosthesis after wearing the soft prosthesis, without sagging feeling and adverse reactions. 2. The main steps of operating the electronic balance

(1) turn on the power and preheat to keep the balance in standby

(2) turn on the balance switch (press the joystick or turn on the key), so that the benchmarking international benchmark of key enterprises of tiansupport new materials is in the zero position, otherwise press the peeling key

(3) put on the vessel, read the value and record it, press the peeling key to clear it by hand, so that the balance will be displayed as zero again. Chenglida instrument provides

(4) add a sample into the vessel until the required weight is displayed, record the reading, and press the print key if there is a printer

(5) take out the vessel together with the sample

(6) press the scale peeling key to clear for reuse

3. Problems that should be paid attention to in the correct dimensional electronic balance

(1) always maintain the environmental sanitation in the balance room, and more importantly, keep the balance weighing room clean. Once items are scattered, they should be cleaned carefully in time

(2) often conduct self calibration or regular external calibration on the electronic balance to ensure that the sensitivity of the balance is in the best state. Chenglida instrument provides

(3) keep the balance well when it is not used for a long time

(4) if the electronic balance fails, it should be repaired in time, and it is not allowed to work with disease

(5) do not overload the operation balance to avoid damaging the balance
