Weight: What is the origin of weight?
Weights are objects used as quality standards on the balance, usually metal blocks or metal blocks, which can be used to measure more accurate mass.
The metal blocks or metal plates placed at one end of the balance according to the quality standard are different in size and each has a certain quality.
A real object measuring ball with a given mass and a specified shape. It is used for measurement in measuring instrument and measuring instrument. The scale must be combined with the balance or balance. (The weight used on the balance is usually called the balance.) Because it can be used to measure the mass of other objects, it is a subordinate physical measuring instrument.
What is the origin of weights?
Each country has only one kilogram. The kilogram standard of China is the standard of tungsten alloy kilogram numbered 60, which was confirmed by the International Bureau of Metrology in 1965. The kilogram benchmark, relevant testimony benchmark, kilogram benchmark, kilogram working benchmark and standard weight constitute the mass value transmission system. In order to measure objects of various masses, the working standard of kilogram is equipped with a set of working standards, which are composed of its displacement and composition. The standards are large in mass, small in size, and few in number, and can be composed of any number. Working standard group and standard weight are usually divided into kilogram group (1-20kg), gram group (1-50g), milligram group (1-500mg), and microgram group or other types of balance combination (such as the upgrading group used by the balance) as required. The combination of weights is usually 5, 3, 2, 1, 5, 2, 2, 1, 5, 2, 1, 1.
How to use weights?
When using, it can not be taken by hand, but only with tweezers or gloves.
Do not touch corrosive substances.
3. Strictly prevent collision or falling, and avoid collision or scratch.
4. Use "size" when using the scale. For example, for an object of about 35g, first take 50g of weight. If the pointer is tilted to the right, replace it with 20g. If the pointer is tilted to the left, add 10g of weight. If the pointer is still tilted to the left, add 5g of weight. Do this until the mass is measured.
What are the weight types and specifications of weights?
1. Balance weight
The cursor of the balance is 5g or 10g, the lower scale is 0.1g/0.2g, and the supporting weight is one 5g, one 10g, two 20g and two 50g.
