Figure IV-72
Figure IV-73 is displayed when a Zero operation was selected. If the current program requires a
Zero step, the spindle rotates backwards until the % torque reading is zero (0). The field after the
word “RPM” is the speed (in rpm) while the field after the word "Torque" is the current % torque
reading. A Zero step ensures that each test is started from 0% torque. In Figure IV-62, the speed
is 0.2 rpm and the torque reading is momentarily at 2.4% as it decreases back to 0%.

Figure IV-74 is displayed when a Wait Time was selected. A Wait Time step allows for a user-
defined time delay before starting the test. The field after the word “Time” is the time, in seconds,
that counts down from the user-defined wait time.

Figure IV-74
Figure IV-75 is always displayed during the actual test, after the aforementioned preparation steps
have been completed. During this portion of the test, data is continuously sent out the serial (RS-
232 port) located on the rear panel of the instrument. This data is for use with the accompanying
EZ-Yield TM software. See Appendix H for more information regarding this data.

At this point, pressing the eNter key starts the test again starting from whichever Run screen is
applicable (see Figures IV-72 through IV-75). Pressing the eSC key returns the display to that of
Figure IV-70, reminding you which spindle should be used.
