国家规定误差:称重1公斤以下的,允许20克的误差;1公斤至2公斤,允许40克的误差;2公斤以上至4公斤,允许80克误差;4公斤以上至25公斤的,允许100克的误差。
计量检定必须按照国家计量检定系统表进行。国家计量检定系统表由国务院计量行政部门制定。计量检定必须执行计量检定规程。国家计量检定规程由国务院计量行政部门制定。
没有国家计量检定规程的,由国务院有关主管部门和省、自治区、直辖市人民政府计量行政部门分别制定部门计量检定规程和地方计量检定规程。
National regulations stipulate that for weighing less than 1 kg, an error of 20 grams is allowed; for 1 kg to 2 kg, an error of 40 grams is allowed; for weighing more than 2 kg to 4 kg, an error of 80 grams is allowed; for weighing more than 4 kg to 25 kg, an error of 100 grams is allowed.
Metrological verification must be carried out in accordance with the national metrological verification system table. The national metrological verification system table is formulated by the metrological administrative department of the State Council. Metrological verification must implement metrological verification procedures. National metrological verification procedures are formulated by the metrological administrative department of the State Council.
If there are no national metrological verification procedures, the relevant competent departments of the State Council and the metrological administrative departments of the people's governments of provinces, autonomous regions, and municipalities directly under the central government shall respectively formulate departmental metrological verification procedures and local metrological verification procedures.
According to the official introduction, the weight error of TEMU should not exceed 100 micrograms (0.0001 grams). This error can be regarded as very small, equivalent to about 1/1000 of the weight of 1 ml of water, or about 1/1000 of the weight of 100 A4 sheets of paper. The size of this error is very important because the accuracy and precision of the experiment are directly affected by it.
It should be noted that the actual error size may be affected by many factors, including sensor performance, changes in environmental conditions, system stability, etc. Therefore, strict calibration and control are required in actual applications to ensure the accuracy of the measurement data.
