UNITS: Toggle between English and Metric units and multiple resolutions for each
unit ( IN - .0001, INHR - .00001, or MM - .001, MMHR - .0001 ), Using the
abbreviation HR to represent High Resolution.
TYPE: Select the bolt material type from a preset list of material types. Each type
contains a velocity, stress factor, and temperature factor. When a type is selected,
these values are displayed in the sub menu items below and can be edited by the
user at anytime.
VELOCITY: This feature allows the user to edit the material velocity at anytime.
Once a material type is selected, the velocity of the selected material type is stored in
this sub menu item and can be edited a by the user if necessary.
STRESS FACTOR: This feature allows the user to edit the stress factor at anytime.

QUANTITY: Selectable units of measure in terms of TIME, ELONGATION, LOAD,
STRESS, and % STRAIN. Refer to page 123 for further info.
LOAD FACTOR: The conversion factor from elongation to Load. This value is
typically determined by performing a field calibration and running a regression or
