3.6 Measuring Reference Lengths
At this point, the MINI-MAX is setup and ready to start measuring reference
lengths. We’ve already setup a bolt group to store the reference length data, and
now need to display the group storage locations prior to making measurements.
Storing a Reading
1) Press the MEAS key once to activate measure menu items. Press the
MEAS key multiple times to move right and the ESC key multiple times
to move left until the LOC cell is highlighted.
2) Press the ENTER key to display the Group View Box.
3) Press the UP, DOWN, LEFT, and RIGHT arrow keys to scroll the target
cell cursor to the desired storage location.
Note: The approximate lengths must always be located in the first column
A for all bolts in the group.
4) Place a small amount of couplant on the transducer and attached it to
the bolt. Make sure that the transducer is seated so that there is no
couplant layer creating a gap between the transducer and bolt. This can
be accomplished by rotating the transducer clockwise and counter
clockwise while applying a very small amount of pressure to seat the
transducer firmly against the bolt.
