Weight for weighing the balance of the yellow calendar

Enlarge the weight first. The added weight should be from large to small, which can save time.

The increased weight starts from estimating the maximum value of the weighed object and gradually decreases. The pallet balance can only be calibrated to 0.1g. Add and subtract weights and move the wandering code on the ruler until the pointer is aligned with the central scale line again. (Small formula: first estimate and then measure the left object and the right code, and then move the code from big to small. )

Tray balance is a common weighing instrument in laboratory, which consists of tray, beam, balance nut, balance, dial, pointer, knife edge, base, balance, stroke code and weight.

Precautions for using extended data:

1, handle the instrument gently, move the travel code to the zero scale ahead of time, and adjust the balance nut to balance the balance left and right.

2. Put heavy objects on the right and objects on the left.

3. Heavy objects should not be held by hand, but should be clamped with tweezers, and should be handled with care. You can't move the code by hand when using the sky.

4. There is a nameplate on the base of the pallet balance, which records the maximum weighing and sensitivity of the pallet balance. When using, be careful not to exceed the maximum weight and not to be less than the inductive capacity, otherwise the tray balance will be damaged or cannot be measured.

5. Don't weigh objects that are too cold and too hot on the balance. Before weighing, it should be put in the dryer to room temperature.

6, after use, put the experimental instrument back in a fixed position.
