MTS Series 793 - Manual (Page 293)

• Warn when a specimen is beginning to fail.
• Shut down the test before the specimen breaks.
When using error detectors, remember that:
• Effective error detection requires a properly tuned servoloop.
• Error limits should be set low on low-frequency and static tests.
• Error limits should be set high on high-frequency tests.
At lower frequencies the error level is usually smaller since the feedback can track the command more closely.
Item Callout
Error 1
Feedback 2
Test Command 3
At higher frequencies the error level is usually larger since the phase lag creates a larger error.
