MiniMax Bolt Tension Monitor
vector using the MiniMax or utility software. Alternatively, the load factor can be
determined using the bolt calculator in the utility software. However, if extreme
accuracy is required, performing a field calibration is a must. This sub menu item
enables the user to edit the factor at anytime. Refer to page 106 for further info.
LOAD OFFSET: Normally the Load Offset is set to zero. However, when a field
calibration is performed and regression calculated a small offset (y intercept) will
result. This value is a constant added or subtracted from the measurement, and will
result in correction to the load quantity. This sub menu item enables the user to edit
the offset value at anytime. Refer to page 106 for further info.
AREA: The cross sectional area of the fastener being measured. Used to calculate
stress. Set to zero if the user is not measuring the quantity in terms of stress. This
sub menu item enables the user to edit the area at anytime. Refer to page 106 for
further info.
EFFECTIVE LENGTH: The length of the region of the fastener under stress (the
distance between the nut plus some amount of additional stress that occurs in the
head and nut(s) of the fastener). This sub menu item enables the user to edit the
effective length at anytime. Refer to page 106 for further info.
4.5 DISP (display) – Menu
VIEW: Selectable RF wave, RECT (rectified), and DIGITS (large digits) views. Refer
to page 124 for further info.
CONTRAST:
Adjustable display contrast for variable light conditions. An arbitrary
scale of 1-20 has been implemented, with the darkest setting at 20. Refer to page
148 for further info.
BACKLIGHT: Selectable OFF, ON, AUTO, or INVERT back light option. Refer to
page 149 for further info.
DELAY: Provides the user the ability to change where the left side of the display
window starts according to time which is converted to a length, in English or Metric
units. Refer to section 12.3 for further info.
WIDTH: Provides the user the ability to change the overall size of the viewable
measurement area. It functions a lot like a zoom on a camera. Refer to section 12.3
for further info.
