4.9.2 Break Detection Activation Threshold
This setting corresponds to the force threshold after which the break detection function is active. The
threshold is provided to prevent false activation of the function during sample handling. The threshold is
defined as a percentage of full scale of the force gauge. For example, for a 50 lbF capacity force gauge, a
setting of 10% represents 5 lbF.
Default setting: 10%
Available settings: 1% - 95% (1% increments)

4.9.3 Break Detection Percentage of Peak
This setting corresponds to the force trigger for break detection, defined as a percentage of peak force.
For example: A sample is pulled until 50 lbF, then breaks. The break detection percentage setting is 60%.
After the sample breaks, the force rapidly decreases to 30 lbF (60% of peak), and causes the test stand
to stop.
Default setting: 80%
Available settings: 1% - 95% (1% increments)
