The Microm II Imperial Film Applicator is a casting knife film applicator with measurements shown in mils. It is available with standard stainless steel or Teflon side plates (Tefrcom), and either a standard stainless steel or Teflon blade.
|Measurement Range:||0-0.250”||0-6.35mm||0.00005" (0.001mm)|
|Side Plate Options:||Aluminum (Standard) or Teflon (Tefcrom)|
|Blade Options:||Stainless Steel (Standard) or Teflon|
Mil Measurement - Used on the Imperial Microm film applicator, each graduation on the Thimble Scale equals 0.001 in. = 1 mil. The first visible number is 1 which is 0.001 in. = 1 mil, the second number is 2 which is 0.002 in. = 2 mils, etc. One complete revolution is 25 graduations = 0.025 in. = 25 mils. The first increment on the Sleeve Scale = 0.025 in. = 25 mils, the second increment on the Sleeve Scale = 0.050 in. = 50 mils, the third increment on the sleeve = 0.075 in. = 75 mils, etc.
Before use, check the zero settings of the micrometers. Place applicator on a polished granite flat plate or alternatively plate-glass of suitable size. Set micrometers at zero. The blade should touch the glass/granite flat plate from end to end without the side plate being elevated. 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 zero point should check within ± 0.0005". If not, adjustment is required, place slight but constant pressure on the top support rods of the applicator with one hand. Rotate the micrometers so the blade is seated on the granite flat plate evenly from end to end and ensure no light is observed. Loosen the set screw on the top of the thimble on the micrometer, this will release the top thimble from the spindle. Align the zero mark on the thimble with the zero mark on the micrometer barrel and secure the set screw. Repeat if necessary to assure a proper zero is achieved. Cautionary Note: Make sure that there is no foreign matter such as iron fillings adhering to the blade magnets as this might result in improper applicator calibration.
