III.6.2.3 Over-Range Condition
Only yield measurements in the % Torque range from 10% to 100% will be accepted. If
Yield Stress is not reached before the measured % Torque value reaches 100%, an Over-
Range error causes the test to end.
The following is sent to an attached printer:
Test (#5: Sample Tst) Complete
Test Failed = Over-range
The following screen is displayed:
YIELD ERROR
OVER-RANGE

III.6.2.4 User-Defined Limit Condition
When an upper and lower limit has been imposed upon the Yield Stress by the user, any
resulting Yield Stress that falls outside these limits causes the test to fail with a Limit Vio-
lation Condition. One of the following messages is sent to the attached printer dependent
upon which limit was violated:
Low Limit Violation
Test (#5: Sample Tst) Complete
Yield Stress (Pa) = 196.53
% Torque @ Yield = 27.4
Temperature = 250.5C
Test Failed = Yield Stress Below Low Limit
High Limit Violation
Test (#5: Sample Tst) Complete
Yield Stress (Pa) = 996.53
% Torque @ Yield = 78.6
Temperature = 250.5C
Test Failed = Yield Stress Above High Limit
The following screen, showing first the violated limit value followed by the resulting Yield
Stress, is displayed:
LIMITS EXCEEDED
YLD:800 (996.53)
