Use 8500C/C+ arrow keys to move cursor (dotted line) to fundamental peak. The
amplitude readout (in IPS) is shown at the top of the display. Write down this
measurement in Column C of Table 5-6.
NOTE: Make sure the frequency readout on the 8500C/C+ display matches that in Column
C to within 0.1 Hz. In this example, the frequency would be 573.0 Hz (34379 RPM).
