Instructions For Use

Attach the arm and ball assembly to the motor shaft by way of the hex screw. Once tightened to the desired position do not forcefully move the arm and ball position without loosening as this can cause damage for the gearbox assembly.



Apply the coating to your test panel using a Gardco Microm Film applicator or equivalent wet film applicator. Immediately place the Drying time recorder on your test panel and lower the clean 3/8 in. weighted Teflon stylus gently into position. Select the desired drying time and the stylus will then begin to be drawn along the test panel. After the selected time cycle is complete the Drying time recorder will automatically stop.



Evaluate the test panel using the supplied Time Template to determine the stages of drying time. Place the clear Time Template over the circular area scribed by stylus and note appropriate scale number of minutes or hours required for the film to cure, the character of the track by the 3/8 in. Teflon ball stylus relate to the drying of the film (Reference ASTM D 5895). Record the results and if desired, record the temperature, humidity and the wet film thickness as these factors are important in considering the drying time of films.
