If the load frame is not self identified, then the scaling
of the extension parameter for the EXTENSION display,
recorder and printer options and the speed parameter de-
pend upon the units in use (inches or millimeters); you
must record this separately.
Area
There are no units associated with Area Compensation
(AREA on the Main Panel). A printout of test results al-
ways lists Area values. This feature is fully described on
page 5-38.
Energy Units
The units shown on a printout of Energy depend upon
the current units in use for load and extension (English,
metric, S.I.). Also, energy units are printed as being di-
vided by Area (1/A) whenever Area is not equal to
1.000.
Energy units consist of the combination:
X ∗
YZ
A
where:
X = units of Load (LB, etc.)
Y = variable of distance (Extension or Strain)
Z = units of distance (in., etc.)
A = 1/Area (used when A = 1.000)
