Note: If the program number chosen has no program loaded, the word EMPTY
is displayed as the program name.
Pressing the MOTOR ON/OFF/ESCAPE key from this screen returns the display to the
PROGRAMS MODE menu.
S Running Yield Programs
When the ENTER key is pressed while a valid program is chosen in the Yield Programs Menu (see
Figure IV-69), the following screen is displayed:
#5: Sample Tst
USE SPINDLE #71
PRESS ENTER
Figure IV-70
The spindle number for the current yield program is displayed on line 3. Prepare the sample, attach
the appropriate spindle and lower it into the sample before continuing. Be sure to use the correct
immersion mark.
Pressing the eNter key with Figure IV-70 displayed performs the following:
• The test is started.
• The pre-test information (test parameters) is sent to both the serial (RS-232) port and to
an attached printer via the parallel printer port. See section IV.8.6.1 for a description of
the pre-test information sent to the printer.
• The program number being run is recorded so that it will be the first program shown the
next time the Yield Programs Menu (see Figure IV-69) is displayed.
Pressing the MOtOr ON/OFF/eSC key at this screen causes Figure IV-69 to be displayed.
After ensuring the appropriate spindle is attached and pressing the eNter key, the various Run
screens are displayed. The top line of the Run screens always displays the program and spindle
number as follows:
#5: Sample Tst S:71

Figure IV-71
Where the program and spindle numbers in use are displayed on the top line. The bottom lines of
the Run screens vary depending upon the options selected in the program.
Figure IV-72 is displayed when a Pre-Shear speed and time were selected. If the current program
requires a Pre-shear step, the spindle will rotate at the selected speed for the selected time. The field
after the word “RPM” is the speed of the pre-shear (in rpm) while the field after the word "Time" is
a time (in seconds) that counts down from the user defined pre-shear time. A Pre-shear step allows
the sample to be conditioned before the actual test is started. In Figure IV-72, the pre-shear speed
is 10 rpm and the pre-shear time is 30 seconds.
