In today's world, scales are very popular for various uses, as they help people accurately determine their weight. There are several types of such devices, each of which has its own principle of operation. Dial scales have been popular for a long time. This is a very important device, which is mainly used in trade and warehouses for weighing food and various other goods.

Desk dial scales

Such scales are very convenient when selling a wide variety of goods. When food is placed on them, you need to follow the scale. If it is within the limits, then in this case the weights are not required, and they quickly return to their original position. A huge plus is that there is a double-sided dial, allowing both buyers and traders to see the weight of the goods.

Varieties

Dial scales are different and are used for different types of goods. They can be either with a sector or with a circular scale. FROMThe dial scale is mainly used for weighing food, often for vegetables and fruits in stores or in the market.

VNC-10 scales are used for weighing small containers. The largest weight for weighing reaches 10 kg.

Characteristics of dial scales

The scales are a weighing system with two platforms: a small one for weights and a large one for goods. The main component of the lever desktop dial scales is an equal-armed lever called a rocker arm. It consists of two uniform stripes. In the middle of this lever there are 2 support prisms, and at its ends there are weight receiving prisms, on which the weight lever on one side and the weight lever on the other side rest.

The load arm is integrated with the quadrant. It acts as an articulated arm and supports the support prism and cushions, which is inserted into the bracket of the balance body and can rotate within the right angle.

The counterweight and tare stabilizer are fixed on it, and it is accompanied by two accompanying arrows. The container stabilizer is a nut that moves along the screw rod. It is intended to accurately zero 2 hands after the balance is released from repair or production.

There is a calibration room under the weight platform. There are scraps of metal that are needed to find the balance in the equilibrium position. The vibration damper is located under the cargo platform and consists of a cylinder, which, in itsturn, attached to the beginning of the scales with two bolts. There is also a piston with two gaps, a rod, a spring, a cap, a cap, and a knurled nut. The rod is attached to the cargo arm. Oil is poured into the vibration damper cylinder itself up to the end of the annular protrusion.

If the adjustment of the damper is correct, then the hands can make several oscillations when weighing in different directions. In order to install mechanical dial scales horizontally, a liquid level is required. When the air bubble is located in the middle of the ring, they are installed horizontally.

Scales RN-ZTs13U

The scales without the use of weights include dial scales RN-ZTs13U. They are needed in order to weigh goods weighing up to 3 kg. The scales have a tare compensator with a tare compensation range from 0 to 400 g.

The composition includes a body, where the main lever is strengthened. The load arm is based on the end of the main arm, while at the top it connects to a string that keeps it from tipping over.

Scales RN-10Ts13U

What are they characterized by? Dial scales RN-10Ts13U are intended for use in trade for weighing various goods. They have the largest weight limit - 2, 3 and 10 kg. When weighing within the scale, weights are not required, as they balance very quickly, and thanks to the double-sided dial, both the seller and the buyer see the weighing result.

Weighing Rules

Basic weighing conditions:

• If the product hassmall weight and it is within the scale, then the use of weights is impractical.
• The use of kettlebells becomes a necessary process if the goods are heavy and significantly exceed the scale value. The weights are placed in the place for the weights. The weight of the product is calculated by adding the total weight of the weights to the scale readings.
• When weighing goods, you need to use fewer weights.
• Weight can only be determined by net weight.
• When selling a product, the tare weight must first be weighed, and only then the product itself, so that the net weight can be determined.
• On the platform of the scales, you can not stack the goods, let alone cut anything, as you can ruin the scales.
• It is forbidden to put different objects under the legs of the scales.
• You can not weigh the goods on scales that are not protected from wind, snowfall and other bad weather.
• It is strictly forbidden to tie kettlebells to scales to increase weight.
• Weights can only be used for weighing. Under no circumstances should they be used for other purposes.
• It is also forbidden to weigh goods on the scales below the norm.

Safety regulations

Be sure to read the safety regulations:

• The scales are installed only on a flat surface. This is very important, and it is desirable that they be about 14-21 cm from the edge of the counter;
• Unscrewed legs should be located at a height of no more than four centimeters;
• Kettlebells can be fromweights on the left.

Checking scales

Before you check, you need to initially understand whether the scales are working. They must have reinforced scales, and the numbers on the dial must be clearly visible. The arrows should be at the same level and stop after 3-4 oscillations. Must be installed by level only.

It is customary to check the sensitivity of the level by placing an iron plate under the legs. The thickness of the plate should be about 1mm.

Stability can be verified as follows. The hand should slowly return to zero. In no case should there be spaces between the arrow and the beginning of the scale. Constancy must be verified when the state of the balance is not loaded. It is necessary to place such a weight on the platform for the goods so that the arrow can remain at zero. Sensitivity is also verified in the same way, but a load must be added to this special weight, and most importantly, this mass should be equal to the smaller division of the scale. Ideally, the arrow should deviate only 1 division.

The accuracy of dial scales is determined by placing weights weighing 500 grams or 1 kg. The balance should then show the correct weight.

Breakdown

Dial scales (we examined the device in the article), unfortunately, often break down. They may not work at all, or they may work, but not quite correctly, that is, it is incorrect to measure weight. At some point, the scales will simply stop showing the exact weight, and this is very inconvenient when selling food and other goods.

Also, products that have a broken seal of the state verification can also be considered faulty. The most significant causes of scale breakdown are mechanical impacts on them and in some cases simply factory defects.

Such actions include strikes on the platform for goods and on the body of the scale itself. It is also possible to damage the balance if it is dropped. The scale has a very sensitive sensor, and it converts the weight of the load into an electrical signal. Thus, a blow to the scales can disrupt its operation or simply ruin it. Various other damages may also occur.

You should always know how to properly use a dial scale, because improper use contributes to the grounding of the scale. Like any system, the scale can fail as a result of a power surge, and nothing can be done.

Sometimes there is such a problem as a manufacturing defect. Very often unpleasant situations occur that some mistake was made in production and not checked. Thus, the goods can get on the counter for subsequent sale. But most often such a problem can be detected before the scales are put up for sale, so there are very few people who come across a defective product.

Repair scales

All devices are repairable and dial scales are no exception. But they can be given for repair only if they have undergone a change in parameters. Thus, the balance is adjusted by calibration. For this adjustment, it is not necessary to change parts and blocks of the scale. You could call this a moderate repair.

It is worth considering thatyou still have to open the case, since any repair is done only in this way. Basically, the verification seal is removed and after repair it is sure to be sent for state verification.

Warranty

In trade, there is one main rule - always under any circumstances give a guarantee for any product. A warranty is a very necessary thing that helps in case of device breakdown. But we must not forget that she can only help if the breakdown was not the fault of the buyer, and provided that her term has not yet expired.

Warranty repairs are absolutely free. The buyer can pay only a small amount of those parts and parts that were used. But this rarely happens, because only the calibration is covered by the warranty.

If the balance is broken due to the fault of the buyer, then free repairs will not be carried out, and you will have to pay money to the service center. The repair service determines the type of repair. Sometimes the scales are sent to the factory, where the manufacturer will tell you exactly whose fault the breakdown occurred and help to resolve this issue correctly.

Sooner or later, any product and any system can break down and even beyond repair. But still, the period of use can be extended by proper handling of the goods. With normal handling and the absence of manufacturing defects, the product can last a very long time.
