Instructions

1, the use of the balance should be placed on the plane table.

2, travel to the left ruler hammer "0" point, the pointer should be aligned with the midline, balance. Otherwise it will rotate at both ends of the adjusting lever adjusting nut.

3, weighing goods, goods and try to put the weight on the central position of the tray.

4, balance and weight should be used with a soft brush and brush wipe clean, keep dry.

5, found that the balance is damaged or not normal should stop using, sent to the factory or repair department to repair the test after passing.

6, in order to ensure the accuracy of the scale, the general inspection once a year, in order to prevent misalignment.

Use notes:

1, weighing the quality of the experiment to use the balance of the tray to do, the lower the balance of the adjustment of the experimental requirements. This experiment is mainly to practice the correct use of the balance, requiring students to operate correctly.

2, to promptly remove groove sludge dirt. As the market to buy the mechanical structure of the tray is not the same, so a careful observation of the demolition method. Generally takes the tray balance behind and in front of the knife file screw, remove the knife file, from around on both sides of the knife knife slot gap, take below tool for wiping and according to the original installed.

[reference]

When the balance is not balanced, the difference of the degree of the swing of the pointer or the left and the right is combined with the sense of the balance, and the quality difference of the weight of the weighed object and the balance weight can be estimated. For example, the pointer to the right side of the 4 division, to the left side of the 1 degrees, the difference is 3 degrees, about 1 on the right side of the 5 division. If the scale of the balance is 0 2 grams, the weight of the weight of the object and its balance is about 0 2 g * 1 5=0. 3 grams. So, you can add about 0 3 grams of weight or mobile swim code about 0 3 grams, you can balance the balance.
