As required, verify and adjust the dolly size by pressing the
button. Select the pressure units by pressing the
button. The instrument will maintain these settings even after
the button is pressed .
NOTE:
The 50.50 square dolly size is used for testing tile
adhesion and should NOT be used when testing with 50mm
round dollies.
4. Zero the instrument BEFORE pumping by pressing the button.
This prepares the instrument for the test by clearing the
display, and zeroing the instrument.
5. Prime the pump slowly until the displayed reading approaches
the priming pressure. The priming pressure is the point that the
instrument begins calculating and displaying the pull rate. It is
also the pressure at which the ability to store readings is enabled.
Priming pressures for the various dolly diameters are:
10 mm
14 mm
20 mm
50 mm
For optimum results, prior to exceeding the priming pressure,
return the pump handle to its full upright position and then
complete a single continuous stroke at the desired pull rate until
the actuator separates the dolly from the coating.
6. Open the pressure relief valve and remove the dolly from the
actuator assembly.
7. Readings may be stored into memory by pressing the
button (memory storage for up to 200 pulls). Press again to review
stored readings. Stored measurements can be accessed using
our PosiSoft Desktop desktop software (pg. 14).
8. To remove all stored test results from memory, press and
