Description
En=(Wn−Mn)/SDn
が適用され、ここでWnは商品nの測定重量である。よって累積誤差は、通常のチェックアウト処理時に処理された商品に関する誤差Enのすべてを算術的に合計したものである。さらに、またあるいは、誤差Enそれぞれの絶対値あるいは大きさの平均を算出することもできる。そして累積誤差と平均誤差は対応する閾値と比較される。いずれかの誤差の計算値がその閾値を超えると、その重量秤は故障しているものされる。
En=(Wn−Mn)/SDn
であり、ここで
Enは、各商品nを計量する秤の誤差、
Mnは、商品nの平均重量、
Wnは、その秤による商品nの新たな重量値、
SDnは、商品nの重量値すべての標準偏差、である。
