4.2 CAL – Menu
Zero Mode: The MINI-MAX is zeroed in much the same way that a mechanical
micrometer is zeroed. There are three zero mode options available in the MINI-
MAX – FIXED, ONE POINT, and TWO POINT. Selecting the proper mode is
dependent on the application requirements. Refer to Chapter 8, for an
explanation of this important procedure.
Zero Value: Depending on the Zero Mode selected above, the actual zero value
will be calculated and displayed in this sub menu item. The user can edit this
value at anytime from this sub menu item. Refer to Chapter 8 for a further
explanation.
Measure Zero: Once the Zero Mode has been selected above, this function
displays and calculates the actual measurement screen containing the known
physical length, velocity, and temperature coefficient of the calibration standard
versus the ultrasonic length. . Refer to Chapter 8 for a further explanation.
Load Cal Mode: Enables and disables the field calibration feature of the MINI-
MAX. This is used to compare known and ultrasonic loads. Refer to Chapter 11
for a further explanation.
Load Cal Calc: This feature is used to calculate a linear regression or vector
curve, once the Load Cal Mode is enabled and known and ultrasonic loads have
been entered and ultrasonically measured. If the regression option was selected
in Load Cal Mode, a correction load offset and load factor will be calculated. If
the vector option was selected, a load factor will be calculated and the offset will
be set to zero. Refer to Chapter 11 for a further explanation.

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.
