Looking at Results
5.1 Positive and Negative results
Once the test is completed, result will get a reading number (top
left) and the Positive or Negative determination will show.
The Federal Action Level for lead paint is 1.0 units or milligrams
of lead per square centimeter (mg/cm
2
).
Lead Paint Mode reports Pb result in mg/cm
2
if Pb is detected. It
rounds the Pb result to the nearest 0.1.
The Positive result means the instrument has calculated that the
concentration of lead is equal to or greater than the
classification level.
The Negative result means the instrument has calculated that
the concentration of lead is less than the classification level.
As some locales have different action levels, local ordinances
should be consulted.
Operators will have the opportunity to change the Classification
Level, if needed, in the Settings menu (Section 7.4).
If lead is not detected, the analyzer will show ND.
Test Mode (Timed vs Quick) will be noted on the screen as well.
See Section 7.5 for more information on these two test modes.
5.2 Depth results
The Depth calculation tells the operator if the paint being
analyzed is non-lead paint or if lead is on the surface.
A Depth value of 1.00 means lead is on the surface. A depth
value greater than 1.0 tells the operator it is underneath
unleaded paint. A larger number (like 8, 10, 20) indicates a
greater number of layers of unleaded paint are present on top of
the leaded paint. The Depth value will not be less than 1.0.
