Analyzer device

The invention relates to an analysis or Computing device which determines the relationship between two input variables in Porm electrical terms and detects when the observed relationship deviates from a given, previously set relationship.

There are no groups in which it is desired to deliver when the relationship between two quantities aloh Handles beyond a given area. For example certain quality control or - »test subjects are used to ensure a given quality level with a minimum actual examination to maintain. A typical scheme involves sequential sampling of the individual units of an item on agreement with given quality standard values are checked. Ss can be desired to discard the whole post if through such sequential sampling is found to be too high a reject rate, and to let the item go through if the rejects a certain one lower level.

The x-axis is provided with a graduation which represents the number of units tested for a given item of unacceptable or discarded entities. The total number of units of the item is represented by point X _n . A line 24 drawn through the point X _n perpendicular to the x axis completes the diagram. The inclination of the lines 20 and 22 ″, the position of the intersection points X ₁ and y _{1 #,} the value of X _n and other features are determined according to known statistical methods.

The application of the diagram according to FIG. 1 is based on the explanations below.
