Figure III-18 is displayed when the yield test fails due to the resultant yield stress exceeding
the user defined limits. The limiting value causing the failed test (high or low yield stress) is
displayed in the first field to the right of the YLD: while the resultant yield stress measured
during the test is the second field.
LIMITS EXCEEDED
YLD:200 (726.36)
Figure III-18
After screen III-15 through III-18 is displayed, pressing the ESC key returns the screen to Fig-
ure III-8. At this point, after ensuring the appropriate spindle is attached, the Enter key can be
pressed to run the test again. Pressing the Enter key when any of these screens is displayed
immediately runs the test again and displays the first appropriate Run screen (Figures III-10
through III-13). When the test is complete, the results are sent out of both the parallel and se-
rial (RS-232) ports.
III.4 Data Output
III.4.1 Pre-Test Output
When a test is begun, the following information is sent out both the parallel and serial (RS-232)
ports in the format shown with each line terminated by a CR/LF (i.e., a Carriage Return/Line
Feed command):
Date : ......................................................................
Sample Information : ......................................................................
Operator : ......................................................................
Model : RV
YD1:Spindle : 71/001 YD2:Pre-shear (rpm/secs) : 0.1/0010
YD3:Zero (rpm) : 0.05 YD4:Wait Time (secs) : 0010
YD5:Run Speed (rpm) : 0.4 YD6:Base Inc. (msec) : 0200
YD7:Torque Red. (%) : 020 YD8:Under-Range Red. (%) : 050
YD9:Average (readings) : 05 YDA:Limits (Low/High)(Pa) : 00200/01000
Base Inc. Cal. (%) : 1.55 Temperature (°C) : 25.5
Test Name : Sample Test Slot Number : 01
Notes: 1) The Base Inc. Cal. (Base Increment Calibration) number is the change in torque
expected for the Base Inc. (Base Increment) selected using the calibration data
stored in the instrument.
2) The YDx values are for use with the EZ-Yield TM software and can be ignored.
