Here are some typical Range settings...
Expected paint thickness Lo Hi
500µm (20 mils) on concrete 130µm (5 mils) 1000µm (40 mils)
50µm (2 mils) on wood 25µm (1 mil) 250µm (10 mils)
The PosiTector 200 measures most polymer coatings accurately
out-of-box with no adjustment required.
To determine if an adjustment is necessary, select a coating
sample of known thickness as close as possible in composition to
the intended application. For best results, the thickness of the
sample should be equal to or slightly greater than the maximum
expected thickness of the coating to be measured.
Measure the coated sample. If the average of a series of
measurements on the sample is not close to the known
thickness...
1. Select the Thickness menu option.
2. Use (-) or (+) to decrease/increase the displayed measurement
thickness value to match the known thickness of the sample.
3. For Advanced models with multiple layers selected, use the
Down navigation button to select the next layer and adjust as
necessary.
4. To save adjustments, use Down navigation button to highlight
OK and press the center navigation button.
When checked, the Gage loads a pre-programmed calibration
adjustment optimized for measurement of polyurea coatings.
