principle
One-hundred-thousandth balance, used to weigh the mass of objects. 1/100000 balance generally adopts strain sensor, capacitance sensor and electromagnetic balance sensor. The strain sensor has simple structure and low cost, but its accuracy is limited, so it can't achieve high accuracy. Capacitive sensor has fast weighing speed and high cost performance, but it can't achieve high accuracy. Electronic balance with electromagnetic balance sensor.
It is characterized by accurate and reliable weighing, fast and clear display, automatic detection system, simple automatic calibration device and overload protection device.

Operation guide
1. When using the rotary switch, it must be opened and closed slowly and evenly. If it is too fast, it will damage the blade, and if it is shaken too much, it will lead to measurement error.
2. Every time weighing, the balance should be closed, and it is absolutely forbidden to increase or decrease the weight when opening the sky, or put the weighed object into the scale.
3. When weighing, properly estimate and add weights first, then open the balance, observe the pointer move backwards, then increase or decrease the weights, and then open the balance again until the reading in the projection screen is still within 10mg.
4. When the weighed object is below 10mg, it can be read directly on the projection screen.
5. The indoor temperature of the balance should be kept at 20 2℃ to avoid sun exposure and eddy current invasion or cold and hot. Silicate desiccant should be placed in the frame cover. Do not use acidic liquid as desiccant.
6. The weighed object should be placed in the center of the scale, and shall not exceed the maximum weighing of the scale.
7. Overheating and supercooling and volatile and corrosive objects should not be weighed in the balance.
8. After using the balance, turn off the brake, hover the weight index to zero, and cover the balance with a condom.
9. When you want to move the whole sky, you must carefully remove the balance beam, left and right balance, ring weight, lifting lug and other parts and put them in the box. Other parts shall not be disassembled at will.
