If not press the Zero button on the digital micrometer to reset the reading to zero. The zero point should check within ± 0.0005". When the applicator is placed between the observer and a bright back light the user should see no light from beneath the blade and side plates. The blade should touch the glass/granite flat plate from end to end without the side plate being elevated. Place applicator on a polished granite flat plate or alternatively plate-glass of suitable size.
Repeat if necessary to assure a proper zero is achieved.īefore use, check the zero settings of the micrometers. Align the zero mark on the thimble with the zero mark on the micrometer barrel and secure the set screw.
Loosen the set screw on the top of the thimble on the micrometer, this will release the top thimble from the spindle. Rotate the micrometers so the blade is seated on the granite flat plate evenly from end to end and ensure no light is observed. If not adjustment is required, place slight but constant pressure on the top support rods of the applicator with one hand.
Caution: Do not wet or submerse micrometer heads.īefore use, check the zero settings of the micrometers. Clean applicator immediately after use and thoroughly dry the blade. Draw applicator toward lower end of panel at an approximate uniform rate of 10 to 12 inches (250-300mm) per second. Pour coating directly in front of the knife-blade. Place applicator at upper end of test panel.
