where the program and spindle numbers in use are displayed on the top line. The bottom line
of the Run screens vary depending upon the options selected in the program.
Figure III-10 is displayed when a Pre-Shear speed and time were selected. If the current pro-
gram requires a Pre-shear step, the spindle will rotate at the selected speed for the selected time.
The rst eld after the word “Shear” is the speed of the pre-shear (in rpm) while the second
eld is a time (in seconds) that counts down from the user dened pre-shear time. A Pre-shear
step allows the sample to be conditioned before the actual test is started. In Figure III-10, the
pre-shear speed is 10 rpm and the pre-shear time is 30 seconds.
TEST #5 SPDL 71
SHEAR: 010 0030
Figure III-10
Figure III-11 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 rst eld
after the word “Zeroing” is the speed (in rpm) while the second eld is the current % torque
reading. A Zero step ensures that each test is started from 0% torque. In Figure III-11, the speed
is 0.2 rpm and the torque reading is momentarily at 2.4% as it decreases back to 0%.
TEST #5 SPDL 71
ZEROING: 0.2 2.4
Figure III-11
Figure III-12 is displayed when a Wait Time was selected. A Wait Time step allows for a
user-dened time delay before starting the test. The eld after the word “Wait” is the time, in
seconds, that counts down from the user-dened wait time.
TEST #5 SPDL 71
WAIT 0010 SECS
Figure III-12
Figure III-13 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 Section II.6 for more information regarding this data.
