The values which are to be transmitted to a peripheral
device when using the
TXD
key on a dual max screen must
now be selected. The following display will appear.
TX 1st PEAK
Sets the AFG to detect the force
at which
a sample breaks but is
not necessarily the maximum force (e.g.
detecting the force at which a tablet first
begins to crack).
TX 2nd PEAK
Sets the AFG to transmit the 2nd peak
only.
TX BOTH
Sets the AFG to transmit both the
1st peak and the 2nd peak.
Use the
UP
and
DOWN
keys to move the arrow cursor to
the desired selection and press
ENTER
.
The display will return to the % 1st PEAK sub-menu 1.
Press
ESC
to return to the main menu page 1, and again
to return to the main display.
When the % 1st PEAK function has been enabled, pressing
the
MAX
key will scroll through the following max display
modes, in order;
1) 1st and 2nd tension peaks
2) 1st tension peak only
3) 1st and 2nd compression peaks (see Fig. 10).
4) 1st compression peak only
5) Current ‘live’ reading
Screen of 1st and 2nd peaks
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.

When setting up the AFG, a
graphical representation of the
test provides a clear insight into
the % drop factor required.
