Attention, users outside U.S.: The 11A Calibrator can also be calibrated under 50Hz light. For 1714
rpm and 923 rpm cam rates, inner two rings on rotor disk are used. Remember to enter half these rates
in 8500C/C+ setup screen, when called for in the following steps.
10494
10494
10200 PHOTOPROBE
NOTE: The calibrator must have no more than one screw installed on its rotor
disk when used with the 8500C; however, the calibrator was designed to have at
least two screws 180 degrees apart. To simulate a second screw, enter the
actual rpm (half the "CAM RATE") as the balance frequency and "2" as the times
factor in the 8500C balance setup display. For example, if the CAM RATE is
900, enter "450" as the balance frequency and "2" as the times factor.
NOTE: 11B users, bypass
mag pulse doubler and
connect magnetic pickup
cable directly to channel A
on 8520C. This simulates
11A use.
