On/Off Button
This button operates from any mode. When pressed, the unit will display the Temperature or, "Press Start" and the Green L.E.D. power indicator will light. Pressing the button again will turn the unit off and interrupt any test in progress, including any changes being made to the configuration data.

Template

Center timer on test panel making sure the arm is counter-rotated eliminating any play in the clockwise motion of the arm.

Make sure the Teflon® ball stylus impinges the painted surface. This is done by adjusting the counter weight at rear of stylus arm to a balanced position.

The 12 gram weight is then mounted on the stylus spindle extending above the rotating arm to give a calibrated weight load.

Weight load on the ball can be adjusted by operator so that results will closely coincide with the finger touch method of determining drying time.


Program Cycle
Program the desired cycle in minutes via the scroll menu. After drying stage is completed, place the clear, plastic template provided over the circular area scribed by stylus and note appropriate scale number degree required for the film to cure hard dry. Calculate the drying time using the following formula:


Formula
DT = (Tc/360) (D)
DT = Drying Time in minutes
Tc = Time Cycle in minutes
D

= Degree on template

The character of the marks by the ball stylus relate to the drying of the film. Record the results and if desired, record the temperature and the wet film thickness as these factors are important in considering the drying time of films.
