Electronic Balance Weighing Unstable Solution(part 2)
Following shared by Lab Electronic Balance Manufacturer.
(3) magnetization of samples and containers
The magnetization of both the sample and the container may mislead the balance into thinking that the force it is subjected to is due to the gravity of the sample. Therefore, we often need to do demagnetization operation when using iron ware.
(4) position of the balance
The placement of the balance is very important. The best place for us to place the electronic balance is in one corner of the house, while the room is better with only one hole and the door closed when we use it. Zanwei brand electronic analytical balance is generally equipped with a windshield, but if there is a wind blowing, or the shaking of the laboratory table, will make the electronic balance reading unstable. The correct position of the balance is equivalent to half of the breakdown of the electronic balance.
(5) sample and container temperature
Temperature has a great influence on the weighing result of electronic balance, so the electronic balance of zanwei brand is generally required to work in a room with constant temperature, while the sample or container obtained from the laboratory may be unstable due to too much difference between the temperature and the environmental temperature of the electronic balance. The high-end balance of zanwei brand will have automatic calibration in general, if it is the balance of a foreign school, manual calibration is required when the temperature changes. This is also an important step to solve the problem of electronic balance.
