Measuring Coating Thickness
1. Select a location to perform the measurement that is flat and
level.
2. Make a mark approximately 50 mm (2") long on the coating,
using the included black marker, or another marker of a color
contrasting to the surface.
3. Pull out the selection dial and turn it to select a cutting tip
based on the expected coating thickness, using the chart
below. If the coating thickness is unknown, perform an initial
measurement using the 2X cutting tip.

4. Place the gage on the surface, such that the cutting tip and
guide wheel are flat and level on the surface.
5. Pull the gage towards the operator, creating a perpendicular
cut through the marked line. Apply just enough pressure to
cut into the substrate.
6. Turn on the built-in light (pg. 3), and align the microscope
over the intersection of the mark and groove cut.
