What is a weight and measure?
Weights and Measures activities can be said to be closely related with the daily lives of humans. Traditionally, the last trading activities confined to the human object length, capacity and weight of the measurement, thus creating the general impression of Weights and Measures becomes the "weigh-foot bucket." However, with the development of science and technology, human measurement activities has been extended to the time, temperature, currents, light intensity, such as the quality of the measurements therefore Broadly speaking, the Weights and Measures shall be measured.

What is the weighing and measuring device?
All for metrology, and to the Weights and Measures units and numerical results of that measurement apparatus or devices, both of Weights and Measures. In our daily life, common-foot, taxi milestone billing table, scales, meters, water, gas Table, oil dollars (tanker), thermometer, thermometer, sphygmomanometer, pressure gauge, ... and so are the Weights and Measures device.

What is the Weights and Measures unit?

Weights and measures, as in kilograms, meters, ... and so is used to indicate quality, and length of physical units. Common has kilograms, meters ... and other metric units (SI units), as well as pounds, yards, and Taiwan jin, Jin, ..., and other nonpublic system units.

What is the metric system?

The metric system is a system of weights and measures unit from cgs (centimeters, grams seconds) system, mks (meters, kilograms seconds), and a system of gradual evolution from, and has now become an international Conference of Weights and Measures (CGPM) implemented by the use of the International System of Units (International System of Unit).

What is the retrospective? What can be reached through the retrospective?

"Grandfather" is defined as: 1 uninterrupted by the standards of comparable pipeline so that a lower level of its individual standard measurement results with international standards or national standards of measurement associated.

General "retrospective" normally reached by the following methods:

1. Standard parts will be sent to the next level laboratory calibration.
2. Use of physical and chemical characteristics of the national standards laboratory analysis, the certification of the standard reference material.
3. "Natural phenomenon" by the definition of standards, as long as the laboratory can produce on its own, not retrospective. The three-phase water, the freezing point, and other substances.
4. Participation in the so-called "security measure for the program," "security measure for the program" concept by the National Institute of Standards and Technology (formerly the National Bureau of Standards) open up, and its main purpose is to assess the participants of the "quantity mapping system "with the national standards" measurement system "of the inter-system error, the above-mentioned" measurement system, "including laboratories, equipment / standard parts, the state of the environment, and other factors.

What is the correct procedure? Basic correction procedures should include those items?

"Calibration procedure" is the implementation of Correction records operating methods and detailed steps of the technical data, which is a measurement based on standard operating procedures. Its aim is cumulative measurement, calibration of relevant agencies (such as equipment manufacturers, other research institutions Correction) correction technique and experience, the whole into a proper correction of operational procedures to provide more accurate use of correction operation. Regardless of the format of the calibration procedure, the following is a correction procedures should include basic items:

(1) all school test, measurement instruments and standard parts of the specifications, the purpose described in detail.

(2) Correction of environmental requirements, specifications.

(3) the use of equipment calibration, standard parts and its minimum requirements specifications.

(4) correction before the preparatory steps and the security considerations of the discussion. If the warm-time zeroing adjustment, cleaning procedures, and should pay attention to all matters shall be discussed.

(5) discuss the contents correction steps, including measurement system structure, the installation of principle, correction operating instructions, data processing, calibration results of assessment principles.

(6) the proper steps after correction, standard parts such as instrument should pay attention to the maintenance procedures.

What is the correction cycle? How correction cycle set?

Correction Period: that the same equipment for twice the time lag correction expected this equipment at this time intervals, in the correctness of its error correction within.
Correction cycle set: In accordance with the apparatus used to frequency of use, operating environment is good or bad, the technical capacity of operators, equipment reliability and the stability and accuracy of demand factors such as cost estimates of individual considerations, it is necessary to set up equipment for a resume set cycle for reference.

What is OIML? The purpose of its establishment? The current number of members?

OIML is "International Organization of Legal Metrology (International Organization for Legal Metrology)," French acronym, set up in 1955, its purpose in the provision of weights and measures and the promotion of the legal system and measurement instruments have a common international basis. Member States have now joined the 55.  

How to exclude electronic scale Fault
1. Weight instability

Whether electric fans, air conditioners or air flow big place, if so requested the removal or replacement of the point of use.

Check whether the AC voltage is not stable or battery power, if requested to replace the use of location or rechargeable.

The above situation can not be resolved, dealers send maintenance.

2. No weight

Error in 10 flu within the volume, if the manual correction recorded instructions, the use of standard reference code can be corrected.

The above situation can not be resolved, dealers send maintenance.

3. After boot or show no adverse reaction

Check whether the burning fuse, if so requested specifications for the same fuse.

Check whether the power line fault, if so requested specifications for the same power line.

Check whether there is a battery or battery power, if it has not requested for the same specifications or rechargeable battery.

The above situation can not be resolved, dealers send maintenance.

4. Counting closed

Whether electric fans, air conditioners or air flow out tuyere big place, if so requested the removal or replacement of the point of use.

Items weighing whether too small to allow more than the average singlet.

Items weighing whether relations sizes due process, more than the permissible range.

Whether the increase in the number of sampling can improve, if unresolved, the other must buy a high-precision scales or counting small Weighing counting scales.
