Digital gram scale weighing the ease of use have been times in the various industries and has been widely used. It not only has high-precision measurement, but also achieved multi-functional, multi-purpose. Current domestic production of digital scales manufacturers has grown to hundreds, mainly in the non-automatic weighing instruments and automatic weighing instruments based.

The introduction of digital weighing technology from the past into the self-development and design of the period, especially for non-automatic weighing instrument's weighing display controller of leaps and bounds. Automatic weighing and weighing hair divided into two categories of non-automatic weighing instruments, commonly used on the market non-automatic weighing instruments. It is mainly used for trade settlement, is also the most contact with the masses of digital weighing, for example, one commonly used price computing scale, digital scales and digital truck scale. automatic weighing instruments are generally more common in industrial and mining enterprises in the batching scales, quantitative packing scale and so on. digital weighing scales mainly by display controller, load cell, and electrical control components, and the rational use of load cell weighing display controller is to determine the quality of plant products the key, which determines the scale of accuracy, reliability, and failure factors and other parameters. How to buy digital scales and weighing a reasonable display controller that the user most concerned about.

First, the digital Scales of purchase

Weighing on the market at present an accuracy grade (III)-level scale, showing the general sub-degree level of 3000 points, the minimum scale value is based on weighing the size ranging from 1g to 50 kg, (for example, the digital Price Computing Scale 15 kg indexing indexing the minimum value of 5g). At the time of purchase: If the price computing scale with 15 kg case.

1.In the empty state and the largest weighing scale state figures show steady (not blinking).

2. With the largest weighing one-third of the weight (or close to the value of the property) placed in the scale table 1 / 4 (to be shared equally weighing table 4) test points within the figures are the same.

3. If conditions take the largest weighing standard weights placed on the scales on the table to test their accuracy.

4. Taken close to the maximum standard Gram weighing Scales weighing (or close to the value of the weight) 3 times repeated loading, testing various figures are the same.

5. According to the function keys, test each function key is good contact, whether the purpose.

Second, the weighing of the Optional display controller

1. The instrument of its functions to sub-types: a single-function, multi-functional and special instruments. Characteristics of the sensor output signal can be connected with the sensor analog output signal can also be connected with digital output signal of the sensor, there are still pricing function, has a multi-purpose table. The series of single-function measuring instrument has A1 --- type, A2 --- counting type and so on.

2. Multi instrument and multi-functional advantages and disadvantages of single-function instrument instrument: its adaptability, can be widely used in various non-automatic with digital scales and automatic digital weighing. But the software development cycle length and the high cost of hardware support, so its manufacturing cost is higher. Single-function instruments: the software development cycle is short, the hardware is also less, so it's relatively low manufacturing costs. Special instrument. manufacturing costs between the single function and multifunction. In terms of the use of failure rate, compared to higher function.

3. Select the instrument consider the issue

a. Select the type of instrument should be the actual needs, rather than the select function better.

b. Production of measuring instruments to obtain permits selection of products.

c. The technical indicators are in line with national standards for weighing display controller.

d. key to assessing their compliance with security requirements.

4. International and domestic weighing display controller dynamic domestic development and production of the instrument is currently a scale with only a general statement, the foreign production of the instrument has been able to use a table with multiple scales simultaneously. Its software features and hardware support can be shared, so that relatively lower manufacturing costs, the use of management costs are also reduced.

5. Note the development of new instrumentation, we should pay attention to the reliability of safety performance, its technical requirements and measurement of the number should be consistent with international recommendations OIML76 the main provisions of the document request, especially in terms of interference with particular attention. This is a general purchase of checks, but can reflect the performance of display technology and the functional requirements of the norm.

6. Maintenance and repair is the proper use and timely maintenance to extend the service life of critical equipment, measuring equipment used to make sure the required environment, the innocent in order to avoid damage to equipment must be familiar with the instruction manual before operating and technical instructions in the confirmation only after use.

If the travel expenses, meals and other operators in, really as good as in Shenzhen to buy it! "

Miss Ho shopper who went straight a few times recently in Hong Kong, had wanted to take advantage of end of the year, as home to relatives and "take along" point of electronic products as gifts, but more down repeatedly in and found that Hong Kong's electronic products are not "imagine the cheap" .

In the minds of many people in Hong Kong is an absolute bar to a "shopping paradise", in particular, many consumers believe that the purchase of electronic products to Hong Kong is a pleasure: not only cheap, but also more trendy styles. But recently many people in Shenzhen found that differentiated the two markets have been gradually reduced, a "shopping paradise", Hong Kong no longer seems to be our only choice.

Miss He had many such experiences. She told reporters that some time ago, she asked her relatives in Shanghai to buy Canon S95 camera, which camera stores in Shenzhen, the price is 2980 yuan, the thought that the price of Hong Kong, where do not provide china free shipping "is definitely cheaper," but only to find in Hong Kong "is not the case . " Gathering in electronic products, Mong Kok, Miss Ho found the prices here actually sold HK 3480, but also can not counter-offer. "Even if the exchange rate multiplied by eight discount for each purchase, the price is almost too pretty and Shenzhen, Hong Kong has not yet counted up the traffic to meals too!" About the shopping experience, Miss Ho address him "too uneconomical."

With this experience, Miss Ho began to "long eye," and not blindly go to Hong Kong to buy things. Later, Miss Ho gradually HTC mobile phones in Shenzhen, and purchased the Panasonic H60 cameras, more down, the price is really cheaper than in Hong Kong. "Saves time and effort to buy, no longer have to be struggling come to Hong Kong to go!"

"Of course, not all digital products in Hong Kong are not worthwhile, some brands and products to Hong Kong is still worth buying." Miss Ho to long-term "Shenzhen-Hong Kong shopping" experience concluded that, in Hong Kong, some high-end mobile phones, computers as two different purchase channels, the price is often cheaper than the mainland. Now greatly sought-for example, "apple", the latest MAC AIR ultra-thin notebook computers, the highest price of the configured version of more than 9,800 Hong Kong dollars in Hong Kong, and Shenzhen in the delay of a few months after the listing, the price even further up to more than 12,000 yuan , a difference of several thousand dollars; another iPhone phone, iPad, and other products, the price gap is not small.

Industry, Choi Lai Choi told reporters that Miss Chan Photography boss, the price of electronic products in Shenzhen than in Hong Kong is indeed low down, as in his shop, Nikon D90 kit price of 6,850 yuan, 2,580 yuan price of the Canon S95, the price certainly cheaper than in Hong Kong . The reason, he said that China as an emerging market, the market consumption increased year after year, more and more attention by the manufacturers. International electronic brands such as Sony, Nikon and so important to China as its target market, starting many new products are located in China. The vendors are happy to reduce prices to expand the mainland market.

He therefore suggested that when consumers buy China electronics, the first clear understanding of the Mainland price, be aware of after, and then compare the prices of Hong Kong to see whether it is worth buying to take home. If the difference between the two places is very small, it is recommended to be purchased locally, but also save trouble in future maintenance effort.
