EXAMPLE
This test would produce a
first peak result
Fig. 11
The dual Max
display now shows
1st peak tension
and 1st peak
compression. Load
currently applied to
instrument is also
shown (0000.0)
The display will show % DROP OFF and SET.
Press ENTER to
change % DROP OFF to % DROP ON. Press DOWN to move
the arrow cursor to SET % and press ENTER.
To determine what precisely is considered a break, you must
define the % drop of full-scale value from the peak load
observed prior to the break occurring.
To set the required % drop use UP and DOWN keys to adjust
the value and press ENTER to confirm the selection.
The % drop value selected also acts as a threshold, below
which the % drop function will not be active.
Example: AFG 100N has % drop of 20 (= 20N). If the peak load
before sample break is 50N, the load must drop to 30N in order for
the AFG to detect a 1st peak of 50N. If load continues to be
applied above 50N (e.g. to 75N), the AFG will return 75N as MAX
and 50N as 1st peak.
