Operation

The procedure required to use the Preset Points Option
is to set the independent variable, set the preset point val-
ues, and then enable the option to get a printout at the
end of a test. The default condition of the independent
variable is the active strain channel or extension if the
strain option is no installed.
To set the independent variable, enter this sequence on
the keypad:
[S1] [5] [+/–]
The main Panel Display will show either:
SL–5 for Strain, or
SL 5 for Extension
Toggle the [+/–] key until the required display appears.
Note
The key sequence [S1] [5] [+/–].....[+/–] also
toggles the Energy integration variable be-
tween extension and strain.
The default values of the Preset Points (PPT1, PPT2,
PPT3) are:
Extension (in.)
Extension (mm) 20
Strain (%)
To set other values within the range of the load or strain
transducer in use, enter the key sequences:
[S1] [41] PPT1 [ENTER]
