                                   measuring  a  single  characteristic  over  an  extended  time  period.  A
                                   system is said to be stable if the results are the same at different points
                                   in time. Stability is illustrated in Fig. 14.5.
                                   Linearity.  The  difference  in  the  bias  values  through  the  expected
                                   operating range of the gage. Linearity is illustrated in Fig. 14.6.
