Use of mechanical balance

Use of mechanical balance:
1  balance test room temperature should be maintained at (15 ~ 30) ℃,  shall not be affected by vibration, air flow and other strong magnetic  field, to avoid direct sunlight. Balancing glass cabinet placed silica gel desiccant, avoid using acidic liquid as a desiccant.
2 rotary switch, must be slow and uniform, too fast will make the  blade anxious to damage, and because of drama shaking, resulting in  measurement error.
3 When measuring the weight, the weight should be placed in the middle  of the weighing pan and shall not exceed the maximum load of the  balance.
4 as little as possible to open the balance of the front door, take the weight, you can through the left and right doors. Close the door to be gentle.
5 When the balance is in the working position, it is absolutely  impossible to pick up the item or weight on the disc, or open the  balance door, or other action that will cause the vibration of the  balance.
6 keep the balance clean at all times, not wet or corrosive items on the weighing plate weighing.
7 weighing is completed, the article should be removed from the balance frame, close the balance switch and the balance door. All weights must be returned to the box and the circle weight indication read back to zero, unplug the power plug.
8 to take the ring weight to be gentle, do not turn the knob quickly to turn the circle to jump or change the weight.
The  scope of application of mechanical balance: mechanical balance is a  widely used in national defense construction, health care, scientific  experiments, agriculture, industry and other fields to measure or  compare the quality of objects measuring instruments. A  wide range of mechanical balances are divided into ordinary scale  scales, digital scale scales and differential scales with dampers.
