Now perform the probe alignment, the gage probe cycle and check the pre-
                   load of the probe as usual. During this procedure the adjustment screws of
                   the cutter head are not tight and may just slightly touch the blades. The
                   above steps conclude the probe zeroing cycle.


                   28.5  Measurement Cycle

                   In the cycle selection choose the measurement cycle (Figure 7) and run this
                   cycle. At this time the master blades shown on the screen are outside blade
                   No. 1 and inside blade No. 2. The cycle begins with blade number 1 and 2,
                   which will be set to zero deviation, as those blades are the master blades at
                   this time.






















                                   Figure 7: Cycle selection – Measurement Cycle

                   The results of a measurement cycle, conducted with a sample cutter head
                   are shown in Figure 8. This chart has to show blades No. 1 and 2 with zero
                   deviation  because  they  were  the  master  blades  of  this  first  measurement
                   cycle. From the radial measurement chart, select the highest outside blade
                   and the lowest inside blade and make those blades the new master blades.
                   Due  to  the  functionality  of  the  electronic  indicators,  those  are  the  blades
                   which have the largest radii. In the example shown, the master blades are
