How do you see how many catties are on the ruler on a large scale?

Taking a scale as an example, the way to look at the weight is as follows:1. Before use, move the weight on the ruler to scale 0;

2.If the ruler is facing up or down, adjust the knob in the right frame of the ruler until the ruler swings up and down;

3.The weight of the object on the scale can be moved forward or backward. When the object does not exceed 10 catties, the weight of the object in the frame is indicated by the frame in which the weight of the object moves. When the object exceeds 10 catties, the weight should be increased little by little until the scale rod of the scale swings up and down.

What is the weight? How many pounds does the scale weigh?

The scale is. A scale is a measuring tool that has been around since ancient times. Steelyard.

It is a principle of using leverage.

A scale for weighing mass. The weight on the rod scale is equivalent to. If a small piece is removed from an accurate scale, the reading when weighing the object will be greater than the actual mass of the object.

The rod scale consists of the first lever, which is concentrated at the outer end of the fulcrum. When weighing, according to the weight of the weighed object, the weight and the weight rope are moved on the scale bar to maintain balance. According to the star point corresponding to the weight rope on the weighing rod during balancing, the mass indication of the weighed object can be read.

The scale is simple in structure and manufacturing process, lightweight and compact, easy to carry and use, low cost, but low precision.

When weighing, you should first look at the scale on the scale, what is the maximum weighing weight; Then look at the use of the scale is used multiple scales, when the scale on the scale to a certain position, the scale swings up and down.

The view of the scale: the shortest grid of the measuring scale represents the catty, the middle grid is the catty, the long is 1 catty, and the longest represents 2 catties. The calculation method is based on the number of kilograms on the scale and the number of kilograms on the scale rod, which is the weight of the item.

It takes fifty-two squares to weigh a hundred and four pounds. In addition, if it is a large scale, it can only be explained according to the actual situation.

The different functions of the scale are generally realized by the instrument of the scale, the more common functions such as weighing, counting, connecting to the computer, printing the scale, explosion-proof, waterproof, etc., and the more special functions such as quantitative control switch valve, upper and lower limit sound and light alarm, etc.

The frame structure is more reasonable, reliable flat or patterned steel plate precision welding, the structure is fastened and durable, the surface is sandblasted, and the corrosion resistance is strong, the safe load is as high as 125%, and the optional anti-skid slope is convenient for the upper and lower loads to drive to the weighing platform in any direction.

Scales are widely used in warehouses, workshops, freight yards, bazaars and other occasions, suitable for lifting goods weighing, forklift shoveling goods weighing, trolley handling goods weighing.

There are 4 steps to look at <> scale. Need to prepare: scales, scales. The following are the specific operation steps to see the scale:

Steps.

Look at the weights of the scale.

Looking at the scale's weights (scales), the maximum weight is 100 kg.

Place the scales opposite the item.

Place a weighing scale relative to the number of the item.

Toggle the slide left and right.

Move the slide on the scale from side to side so that the ruler is suspended and cannot touch the top and bottom.

Calculate the weight of the object to be weighed.

The number on the left side of the scale (kilogram weight) plus the number of the pound (kilogram weight) is the weight of the object to be weighed. end

The method of how many catties of scales: first look at how many kilograms each scale represents, and then look at the numbers, 1 kilogram is equal to 2 catties, such as 52 kilograms is 104 kilograms.

Scales are also called, scales, or instruments that measure the weight of unequal arms are called scales, or refer to the lifting bars that weigh the weight of things by looking at the scales, or single finger scales. During the Warring States period, there were unequal arm scales. When domestic pole scales began, there is no conclusive jury.

The world's most primitive scales, and their physical evidence was found at the site of the Indus River civilization in present-day Pakistan.

Three or four thousand years of history.

The unearthed copper weighing rod of the king of Chu, with a scale of ten equal parts, is speculated to be a weighing instrument that appeared when transitioning from an equal-arm balance to a rod scale as a sign of hanging weights and weights in different parts during weighing. After the Eastern Han Dynasty, it evolved into a scale that looked at the weight from the scale star.

Introduction to electronic scales

Electronic scale is used to weigh the goods of the automatic weighing equipment, through the sensor of power conversion, through the weighing instrument processing to complete the measurement of goods, suitable for the measurement of various bulk goods.

The weighing items are converted into analog signals of voltage or current by the weight sensor installed on the mechanism Hermin, which is converted into digital signals by the AD processor after amplification and filtering, and the digital signals are processed by the ** processor, and the peripheral functions and various interface circuits are also connected to the CPU for application, and finally displayed digitally by the display screen in a Zen branch digital way.

The main components are weight sensing, amplifier circuit, filter circuit, analog-to-digital converter, processor, power supply circuit, button, shell, mechanism, weighing pan.

The unit of the rod scale is kilogram and catty, which can be distinguished by looking at the scale identification of the rod scale or the identification on the scale.

1. The maximum range of this scale is 20 catties, there are two rows of scales on the rod body of the scale rod, there are two lifting ropes at one end of the weighing hook, and the weight of the scale is 1 catty.

2. The rod scale uses the principle of the rod bar, and the rope lifting close to the weighing hook can be weighed as a larger object, and the lifting range of the rope is smaller at the left point.

If there are 9 long needles and 10 short needles in between, then you are kilograms; In this case, one short one is a kilogram and a long one is 1 kilogram. If there are five short needles and four long needles in between, then you are 65 kilograms. One short is 1 kg and the long one is 2 kg.

2. Mechanical scale, that small grid is 1kg, and the data is relatively vague. If it is an electronic scale, it is more convenient, it is directly displayed by numbers, the electronic scale is better than the mechanical scale, the mechanical scale is used to weigh the spring more times, the spring will be deformed, resulting in the data weighed out is not so accurate, and the electronic scale uses four sensors without this concern, the mechanical scale pointer display, not easy to read. Electronic scale, direct digital display, easy to read.

If it is the weight type, 1 kilogram is 2 catties, so the weight on the kilogram scale multiplied by 2 is the actual weight in kilograms.

The weighing is 40 kilograms, and the actual weight is 80 kilograms. It's all calculated by kilograms, and if you multiply the reading above by 2, it's a catty.

The kilogram scale value of the electronic scale is measured in kilograms, such as readings, which is catties, that is, 1 catty and 7 taels.

Precautions for using electronic scales

1. Keep it dry, do not use it in a place with water stains, and do not rinse with water.

2. Do not stack items on the weighing surface when not in use, so as to avoid a large amount of battery consumption and cannot work normally.

3. Do not hit the scale body hard to avoid damaging the sensor.

4. If you don't use it for a long time, you can dial the dial switch at the bottom of the scale to the middle "off", and you can cut off the power supply; The toggle switch is turned to the left end as "kg" and the right end as "lb", which is used to select the weighing unit and turn on the power supply.

5. The electronic scale is a precision electronic scale, which should be carefully stored and used correctly to avoid moisture, drop collision, heavy pressure and exposure to the sun. Do not rinse directly with water, if the appearance is dirty, please clean it with a soft cloth dipped in water, and it is strictly forbidden to use benzene, nitro solution or liquid caustic soda for cleaning.
