Laboratory electronic balances are one of the more commonly used weighing operation supplies in laboratories.
The weighing technology of micro balances, semi-micro balances, analytical balances, tray balances and precision balances has been greatly developed. Normally, weighing operations can be carried out without a specially designed weighing room.
The development of electronic technology has greatly simplified the operation of the balance, significantly shortened the weighing time, and has good adaptability and can be directly integrated into the production process. The following are the methods and steps for using the electronic analytical balance/tray balance:
1. Fold the electronic analytical balance neatly and place it on the balance frame.
2. Before use, open the front door of the scale and use a soft brush to clean up the dust that has fallen on the scale pan and inside the scale
3. Place the weight on the tray balance and weigh the approximate weight.
4. Check the balance for zero point. Open the left door, place the weighed object in the center of the left plate, and close the left door.
If the weight is less than 10 grams, it can be read out on the projection screen. 10 mg to 990 mg rotatable coil code
Indicator dial knob to increase or decrease the ring weight. (Be careful to take and place the coil code gently and slowly, and turn the indicator plate too fast
Knob, which will cause the ring-shaped weight to jump or shift) Select a weight from 1 to 100 grams to open the right door
Use tweezers to pick up the weight in the weight box, place it in the center of the right plate, and close the right door.
5. Start the switch knob of the electronic balance (note that when turning the switch knob, it must be slow and evenly, or too fast may cause
The blade is damaged due to sharp contact, and measurement errors will also be caused due to excessive shaking). Offset by pointer
Direction, increase or decrease the weight until the reading displayed on the projection screen is within 10 mg.
6. Record the weight of the object being weighed, check it again, and turn off the balance switch knob.
7. When weighing each time, it is never allowed to increase or decrease the weight, take and place the weight when the balance is opened,
8. After weighing, take out the weight from the balance. The weights used must be put back into the weight box with tweezers and closed
Tianping Gate. And return the reading of the coil code indicator plate to zero. Unplug the power supply and put on the balance cover.
