Use common sense of saidoris balance

avoid installing on busy channels, It is best to have a special balance with only one door

don't put the balance in the window to avoid direct sunlight in the window to avoid direct sunlight away from the heat source or other radiation sources away from the heat source or other radiation sources

avoid the air conditioner or fan blowing directly to the balance to avoid the air conditioner or fan blowing directly to the balance. Don't have a large air flow through the balance. Don't have a large air flow through the balance

reduce the temperature drift, and don't let the high gloss The balance of heat-resistant plastic parts is close to the heater. Don't let the balance close to the heater. Keep the indoor temperature constant

monitor the humidity to keep it constant. Monitor the humidity to keep it constant, Tips: the experimental methods of mechanical properties in the experimental standard of plywood for container floor are all carried out by referring to the method of microcomputer controlled wood-based panel universal experimental machine that meets the GB-T 17657 ⑴ 999 standard. The recommended value is 45%-45%-60%60%

do not use high-power bulbs. Choose sunlight in windowless rooms. Choose fluorescent lamps for lighting in windowless rooms.

the weighing table should be able to not conduct seismic sources.

the table surface should be guaranteed Flat and straight without depression. The table should preferably have anti magnetism function

selection of weighing table: you can choose the stone plate supported by the wall, you can choose the stone plate supported by the wall, or the floor cement table or the floor cement table, the table top should not be covered with glass, and the table top should not be covered with glass, plastic or metal table top or metal table top

note: please read the weighing value within the shortest time after the balance is stable; Do not touch the peeled containers and samples directly with your hands. You can use tweezers or other tools to take them; Do not put your hand in the weighing room of the balance. Use a long pair of tweezers to ensure that the sample is put in; Do not use glass or plastic containers to hold samples when the indoor humidity is lower than 30% - 40%; Pay attention to the influence of sample surface moisture on weighing. It is best to heat and dry the sample first, weigh it when its temperature cools to room temperature, and Japan Steel in East China will reduce the coke purchase price by 30 yuan/ton; The influence of static electricity will make the weighing result heavy or light

physical factors affecting weighing:

the influence of static electricity on weighing can be minimized by the following methods: use static electricity elimination hair dryer, ground the weighing plate, increase environmental humidity, and the operator does not wear nylon jacket

the influence of air buoyancy. The weight of the sample in the air is affected by buoyancy. The buoyancy depends on the small volume of the sample, atmospheric pressure, air density, temperature, humidity and altitude

magnetic samples will seriously affect the repeatability index of the balance. Demagnetize the samples or shield them with thick metal plates
