To make adjustments:
1. Measure the coated part.
2. Select the Set Gates menu option.
3. Gate A can be changed first. Adjust the value
down (-) or up (+).
Press to accept the value and to move to
Gate B.
4. Gate B can now be changed. Adjust the value
down (-) or up (+).
5. Press to accept the value. Standard models
will exit.
6. Advanced models will display a Cursor which
allows analysis of the peaks displayed in the
Graph. Adjust the Cursor down (-) or up (+).
Press to accept Gate values and exit.
Use the Cursor to measure
multi-layer coating systems with
more than 3 distinct layers.
NOTE:
Here are some typical Gate settings...
Expected paint thickness Gate A Gate B
500um (20 mils) on concrete 130µm (5 mils) 1000µm (40 mils)
50µm (2 mils) on wood 25µm (1 mil) 250µm (10 mils)
The displayed thickness reading may
change when Gate values are adjusted. The new
thickness value represents the distance to the
"loudest" interface within the new A/B Gate values
(see pg.2). This handy feature makes it easy to
ignore other measurements such as surface
roughness.

Notes (pg.15)
