1. The action should be slow and light: the lifting rotor should be slowly opened and opened to the maximum position, and the ring code should be slowly turned to prevent the ring code from falling off or dislocation.
2, the weighing object can not be directly placed in the weighing plate, according to the different properties of the weighing object, can be placed in the paper, surface dish or measuring bottle. Do not weigh more than the maximum load of the balance.
3, the balance can not be changed in the same weighing process, so as to avoid relative error.
4, the use of analysis days in addition to should follow the relevant operating rules of the pallet balance, should also pay attention to: add weights, take weigh sample or other reasons to contact the day should first balance beam, otherwise easy to make the knife edge damage, this is the most important rule in the use of balance. The balance door should be closed every time you weigh it. After the weight is added, the pendulum of the pointer should be controlled between 2 and 4 grids. The sample is weighed in a clean and dry weighing bottle or surface dish depending on its properties. The measuring bottle should not be handled by hand. It should be picked up by filter paper. At the end of weighing, check whether the balance beam is well supported, whether the weight is complete, whether there are drugs scattered into the balance, whether the balance door is closed, and whether the cloth cover is well covered. After a period of use, the balance should be sent to the metrology department for verification and adjustment. A full cleaning of the balance should be carried out twice a year.
