Test Screen Display Functionality
The user may tailor the test screen with any number of combinations, selectable by on/off toggles. From
the Main Menu, go to Setup>Test Screen Display (Fig. 162 to 163).
Individual settings are shown in Fig. 164. Positive/Negative permits you to turn off a Positive/Negative
result when compared to a threshold value of lead in paint. It may be useful to you to turn off
Positive/Negative for commercial/industrial lead inspection work, where one is typically looking for
accurate measurements for a lower level of lead. The factory default for this setting is “ON.”
Precision displays/hides the two-sigma (95% confidence). It is often turned “ON” in combination with
Positive/Negative “OFF”. The factory default for this setting is “OFF.” We don’t recommend turning it
“ON” in conjunction with Positive/Negative set to “ON” as Action Level mode already takes into account
the Pb200i’s two-sigma confidence as to whether the result is positive or negative when compared to an
action level of 1.0 mg/cm
