What problems should be paid attention to in the use of analytical balance?

Analytical balances should be used according to the procedure:

1. Adjust the level: Before starting the analytical balance, you should observe whether the water bubble in the level at the rear of the analytical balance is located in the center of the ring, otherwise, adjust it through the anchor bolts of the analytical balance.

2. Warm-up: When the analytical balance is turned on for the first time or turned on after a long-term power failure, it needs at least 30 minutes of warm-up time. Therefore, under normal circumstances, the laboratory analytical balance should not cut off the power frequently.

3. Weighing: Press the ON/OFF key to turn on the display; wait for the instrument to self-check. When the display shows zero, the self-test process is over, and the analytical balance can be weighed; place the weighing paper, press the Tare button on both sides of the display to tare, and when the display shows zero, add the reagent to be weighed to the weighing paper weighing. After weighing, press the ON/OFF key to turn off the display. The following is a professional introduction to the problems that should be paid attention to in the process of using the analytical balance, hoping to attract the attention of the majority of analytical balance users.

Analytical balance should pay attention to the following issues during use:

(1) In order to use the analytical balance correctly, you must be familiar with several states of the analytical balance: O is displayed in the upper right corner of the display: indicating that the display is off; O is displayed in the lower left corner of the display: indicating that the instrument is in standby and can be weighed; A diamond-shaped mark appears in the corner: it means that the microprocessor of the instrument is performing a certain function and does not accept other tasks at this time.

(2) The analytical balance has been strictly calibrated during installation, so the analytical balance cannot be easily moved, otherwise the calibration work needs to be performed again.

(3) It is strictly forbidden to weigh directly without using weighing paper. After each weighing, please clean the analytical balance to avoid polluting the analytical balance and affecting the weighing accuracy, as well as affecting the work of others.
