Nantong Dashunyu: Usage and maintenance of precision electronic analytical balance

When weighing the price, put the clean weighing bottle or weighing paper on the weighing plate, close the side door with the precision electronic balance, and press the peeling button lightly. One ten thousandth of the balance will automatically check the zero point, then gradually add the substance to be weighed. Divid one of the balances until the required weight.
5. The weight of the electronic balance is called the actual value displayed on the balance display when the mark appears in the lower left corner of the display.
6. At the end of the weighing of the cherry blossom electronic balance, the weighing bottle (paper) should be removed in time. For one thousandth of the balance, the side door should be closed, and the one-thousandth of the balance should be cut off and the usage registration should be completed.

One thousandth electronic balance notice and maintenance
1. One-thousandth of the electronic balances should be placed on a stable and firm cement or marble table. The room where the precision electronic balance is placed requires clean, dry and constant temperature, and the light should be prevented from directly hitting the balance.
2. When weighing the electronic balance, the material should be taken from the side door. When the balance is read, the door should be closed to prevent the air from flowing and causing the balance to swing. The front door is only used when servicing or removing residual materials.
3. If the precision electronic analytical balance is not used for a long time, it should be energized and preheated regularly, once a week, and preheated for 2 hours each time to ensure that the instrument is always in good condition.
4. The moisture-absorbing agent (such as silica gel) should be placed in the electronic balance box. When the moisture-absorbing agent absorbs water and discolors, the electronic analytical balance should be immediately replaced by high-temperature baking, and the balance should be analyzed to ensure moisture absorption performance.

5. Precision electronic balances should be weighed in a weighing bottle with a cover when weighing volatile, corrosive, strong acid and alkali substances to prevent corrosion of the balance, so as to avoid unnecessary losses.
