What is the precision of the fully automatic multihead weigher? Under the same standard, the same test sample is continuously tested on the net weight scale. If the total number of tests is sufficient, it will show a standard normal distribution curve (also called a Gaussian curve). In the standard normal distribution, σ means relative standard deviation (STDDEV), and μ means mean net weight. Generally, everyone±3σ(±3 times the standard deviation) to define the precision of the net weight scale, that is, the probability that the net weight of the test sample is all distributed in (μ-3σ, μ+3σ) is 0.9974, and the detected net weight value is basically concentrated in (μ-3σ, μ-3σ, μ+3σ) section, the probability of exceeding this category is less than 0.3%.
To put it simply, 1,000 tests are allowed, and the number can be passed at most 3 times. For a given commodity, under a certain inspection standard, the smaller the relative standard deviation value, the higher the dynamic precision of the inspection scale. However, the dynamic precision must be established under the premise of the given commodity, the given inspection standard and the given precision definition method.
