The instrument begins building pressure (priming stage) and a
green animated arrow (up) appears on the display. When the
priming pressure is achieved the LCD starts displaying pressure
versus time on the chart.
Pressure build-up stops when the dolly is pulled from the
surface, the pull limit has been reached or when the
pressed. The maximum pressure value will blink on the display
and a red animated arrow (down) will display while the pump
retracts the actuator.
CAUTION: To avoid injury, keep fingers away from the
quick coupling and actuator assembly until the pull test
has completed and the actuator has been fully retracted. Press the
stop button to abort the pull test at any time.
NOTE:
Setting a Pull Limit or stopping the test before a fracture
occurs is useful when the coating strength exceeds specified
requirements.
5. Remove the dolly from the actuator assembly.
6. Examine the dolly and surface to analyze the result (pg. 8).
Recording the Result
If a memory batch is open, the maximum pressure result is
automatically stored into memory (pg. 9). Pass/fail, pull
parameters, date and time are also recorded.
The nature of the fracture (cohesive, adhesive, glue), batch and
reading notes can also be recorded. Swipe the touch screen
horizontally or use the left/right buttons to navigate to the
appropriate view and select Edit. See Memory Views (pg. 7).
