SElECTING % DROP vAlUE
The “% Drop” is the percentage drop value. This
represents how much the measured load must
drop from a previous maximum load for the DFS II
Series gauge to identify the break load.
A Sharp Break has a fixed percentage drop of
95%. It presents the 95% value from full scale. If
the maximum load is 100 lbf and the % Drop is
95% (for a Sharp Break), the break load will be
at 95 lbf. At 95 lbf, the DFS II gauge will “end the
test”. If the gauge is used with a TCD tester, the
gauge will signal the tester at 95 lbf to stop the
test.
A Percentage Break is a user-defined percentage
drop. You may specify the % Drop to be from 1%
to 99%.
To change the “% Drop” value, select the F2
(Percent) key. The cursor arrow will now point to
the “%Drop” label.
Select the proper increments using the LEFT and
RIGHT navigation arrows. The LEFT arrow
decreases the increment value. The RIGHT arrow
increases the increment value.
Use the UP arrow to increase the “%Drop” value.
Use the DOWN arrow to decrease the “%Drop”
value. Select Enter when the required % drop
value is displayed.
