Viken Detection Pb200i - Interpreting Measurement Outcomes

Page 11
Once the measurement is determined to be Positive or Negative, the shutter will close, the warning LEDs
will turn off and the result will be displayed and saved.
Typical measurement times in Action Level (PCS) Mode take 1 to 3 nominal seconds; the closer the
measured value is to the action level, the longer the testing time will be. The maximum measurement time
in Action Level mode is five nominal seconds without iRTA and ten nominal seconds with iRTA. The
results shown in the examples in Figure 25, 26, and 27 are based on an action level of 1.0 mg/cm

.
Caution: The Action Level can be changed on the Pb200i by a user with administrative rights, but
the Pb200i’s Performance Characteristic Sheet (PCS) only pertains to lead inspections with an
Action Level of 1.0 mg/cm
