用单个比较器（K），实际值（XI）最初到下限（UG）和上限值（OG）被选中。 在比较器输出躺在公差窗口Istwerde（XI）内解决的二进制“01”，并且在存储器（SP）被存储时，先前已经带到状态“10”。 仅是这些国家适当的公平条件存在的公平序列时。 设备检测到组件的可能性“沉睡的错误”。

With a single comparator (K), an actual value (x _i) initially to a lower limit (UG) and then to an upper limit (OG) is checked. Lying within the tolerance window Istwerde (x _i) solve a binary _"01" at the comparator output and stored in a memory (SP) filed, which has previously been _"10" brought into the state. Only with proper sequence just these states there is also a regulatory compliant state. The device detects the possibility _"sleeping errors" of components.
