Charging the Batteries
The Pb200i requires 6 AA batteries. Only use rechargeable Nickel-Metal Hydride cells or disposable
Lithium Ion cells (we recommend Energizer Ultimate Lithium).
Caution: Do not use alkaline batteries, as they will not provide the proper power for the system.
1. Identify the positive and negative ends of the batteries and insert them into the smart charger.
Once the batteries are inserted correctly the LCD will turn on as indicated by the black bars in the
charge indicator.
2. The batteries are fully charged when you see 4 solid bars on the LCD display and the lights are
no longer blinking. Fully charging the batteries typically takes 5-6 hours. Caution: be sure that
all six batteries are fully charged. If one or more AA batteries are not fully charged, it will
shorten the useful life of the battery pack.
3. Caution: We recommend using the “Refresh” button on the battery charger at least once every
two to three months. The refresh process typically takes 12 hours. There are four green refresh
buttons, one per each bank of four batteries.
4. Once the batteries are fully charged they are ready for use in the Pb200i. We recommend leaving
the charger plugged in, and the batteries inserted in the charger so that maximum charge is
available for use of the Pb200i. Do not leave batteries in the charger while charger is unplugged,
as they will discharge at an accellerated rate; rather, insert the batteries in the battery holders for
transport or storage.
Caution : Do not mix different manufacturer’s batteries in the Pb200i battery holder. This may
cause a reduction in your battery life.

Insert the battery pack with the negative terminal facing the spring, two AA batteries per side, so that all
six chambers of the battery holder are filled (Fig. 6 and 7). Double check that batteries make complete
contact with each other and the springs; adjust as necessary. Follow this link to watch a video tutorial on
the batteries.
Remove the battery door on the bottom of the Pb200i. Slide the battery wedge to the side. Insert the
battery holder with the arrow facing the front of the instrument (Fig. 9). Apply slight upward force to seat
the battery holder properly; when fully inserted the battery pack should sit firmly against the battery ledge
(Fig. 10). Secure the battery holder in place with the battery wedge. Replace the battery door (Fig. 11).
The latching mechanism will click when the battery pack is seated properly.
Caution: Inserting the battery holder with the incorrect orientation will not damage the Pb200i, but
the instrument will not turn on.
Caution: Use care when removing the battery wedge. If broken, your Pb200i will need to be
returned for non-warranty repair.

Powering On and Initializing the Pb Application Software
1) To power on the instrument, press and hold the Power ON/Off Button until the instrument turns
on.
Caution: The instrument will go to “sleep” after 10 minutes of inactivity. Press any button to
reactivate the instrument.
2) Once the Pb200i has completed its boot-up sequence, the LED will turn green and the home
screen will display an Android application showing the “Pb” icon (Fig. 12).
To access the application:
a. Touch the “Pb” icon on the home screen (Fig. 12).
b. On the next screen, enter the password assigned to you by your Compliance or Safety
Officer. Touch “Login” under the “Password” text to activate the keyboard (Fig. 13).
c. Review the Warning Screen and confirm that you understand that the instrument
produces ionizing radiation when the safety shutter is open and the warning lights are on
(Fig. 14). If you are not familiar with the radiation safety, please press “I Do Not
Understand” and read the Radiation Safety section in this User Guide before you return
to this screen. If and when you do understand that the instrument produces ionizing
radiation when the safety shutter is open and the warning lights are on, please select the
words “I understand” to proceed to the next screen.
Caution: If you do not fully understand the warnings on the Warning Screen, please press the
Back button. Do not in proceed before you reread the Radiation Safety section in this User Guide
(see page 45).
d. On the next screen Select “Test” (Fig. 15).

Taking a Measurement
The Pb application is designed to open and close the safety shutter of the instrument, exposing the
sample in front of the Pb200i measurement window to x-rays and gamma-rays produced by the sealed
radioisotope source in the instrument. The safety shutter can only be opened by pulling the trigger of the
instrument while the proximity button at the top of snout of the Pb200i is fully depressed against a
surface.
1. To depress the proximity button, place the front of the instrument’s snout flat against the
sample surface. The “Power indicator LED/Proximity button indicator” will turn green when
the proximity button is properly depressed (Fig. 16).
2. Pull the trigger.
Caution: the proximity button must be depressed before pulling the trigger.
When the Pb application is running on the Pb200i and the trigger is pulled with the proximity button
depressed, the shutter will open. The LEDs on the left and right side of the instrument will turn on and
emit red light. The red lights indicate that the shutter is open. If any of the conditions above are not met
during the measurement process, the shutter will close immediately and the red LEDs will shut off. Once
the shutter is open, it will remain open for a maximum of 5 minutes.

Testing the Accuracy and Precision of the Pb200i
The Pb200i should be tested for Quality Control (QC) before each inspection, every 4 hours, and when
the inspection is complete.
1. Start by placing the wooden reference block (Fig. 17) on top of the Pb200i case. Hold the device
with the proximity button against the wooden reference block, with the snout of the instrument
centered on the paint film nearest 1.0 mg/cm2. When the LED turns green (Fig. 18), squeeze and
hold the trigger, keeping the device’s snout in firm contact with the block while continuing to hold
the trigger (Fig. 19). The reading will automatically terminate (Fig. 20) when the device has
determined whether the sample is classified as Positive (when Pb≥1.0 mg/cm2), or Negative
(when Pb<1.0 mg/cm2).
2. Compare the result to the value on the reference block and make a note of the reading.
3. Complete the test 3 times, then average the readings. The average (rounded to 1 decimal place)
of the three readings must fall between 0.8 and 1.2 mg/cm2(inclusive) for the Pb200i to pass its
QC check in accordance with the Performance Characteristic Sheet (PCS).

Performing an Inspection with the Pb200i
Pressing the trigger initiates the measurement. As the reading is taken, you will see the results on the
screen change to reflect the measurement data (Fig. 21 and 22).
Once the reading is recorded, scrolling from the bottom up will allow the user to view the GPS
coordinates (Fig. 23) and spectrum of the reading taken (Fig. 24).
Result
Action Level indicates “Positive”
or “Negative” result. “NULL”
indicates the reading was
terminated before a
determination could be made.
