SElECTING bREAK POINT
The “Break Point” is the break detector value or the
“break trigger”. It is the force value that must be
acheived before the gauge will look for the maximum
load and the peak load.
It is important to set a correct “Break Point” based
on the type of sample and the sample’s break
characteristics.
In a peel application, if the break point is set too
low, the gauge may sense a break due to the
characteristically noisy signal produced by a peel
application. In a peel test, it is quite easy to have
a 95% drop from a maximum load that is not
representative of the true maximum load or true
break load.
If the break point is set too high, the gauge may
never see a break.
The best way to establish the break point is
through sample testing trials.
Break Point - sharp Break Method
To set the Break Point in a Sharp Break setup,
establish the correct increment value. Use the UP
navigation arrow to increase the Break Point value,
and the DOWN navigation arrow to decrease the
value. Select Enter once you have the desired
Break Point value displayed.
Break Point - Percentage Break Method
To set the Break Point in a Percentage Break setup,
establish the correct increment value. Position the
arrow cursor next to the label “BkPt”.
If the cursor arrow is next to the “%Bk” label, select
the F2 (BKpt) key. This will reposition the cursor
arrow next to the “BkPt” label.
Use the UP navigation arrow to increase the Break
Point value, and the DOWN navigation arrow to
decrease the value. Select Enter once you have
the desired Break Point value displayed.
