Step 6: Storing Pull-Off values into Memory

The PosiTest’s internal memory stores maximum pull pressure, pull rate,
test duration and dolly size for up to 200 pulls.

Press the button upon completion of a test to store pull-off test
results. The display will show the pull rate and alternate between the test
number and the maximum pull pressure for that test. The con will
appear to indicate that there are test results in memory.

Press the button repeatedly to view previously stored test results.
The PosiTest AT-A also displays dolly size and pull rate by
pressing their respective buttons.

Complete information on all test results can be downloaded to a PC and
viewed using the optional PosiSoft software. Test results are not erased
from memory after downloading. Press (AT-M manual) or
(AT-A automatic) to exit viewing mode.

To remove all stored test results from memory, press and hold the
or button, then press the button. The icon will
disappear from the display.

All settings and test results in memory are retained during power-down.

Test results can be considered 100% valid when the coating is completely
removed from the substrate. When only a portion of the coating is removed, spe-
cific results should be noted including the fracture pattern to determine the cohe-
sive properties of the coating and adhesion properties between the dolly and
adhesive, adhesive and coating, distinct coating layers, and coating and sub-
strate.
