Installing the Batteries
The Pb200i requires 6 AA batteries. Only rechargeable Nickel-Metal Hydride cells or disposable
lithium cells should be used in the system. Insert the battery with the negative pole towards the
spring, two batteries per side, until all six chambers are filled (Fig.1, 2). Note that the positive
and negative positions are marked on the top of the battery assembly (Fig. 3).

Remove the battery door of the system. Place the battery holder in the system, positive
terminal facing the left side of the instrument (Fig.4). The end of the battery holder with the +-

marked end should be inserted so it faces the top of the instrument. Apply upward force to seat
the battery holder properly, and when fully inserted, push to the rear to have the battery holder
sit on a ledge in the handle (Fig. 5). Replace the battery door (Fig.6). With the software currently
on the system, the unit will immediately boot, as indicated by the LCD illuminating and the LED
above the LCD turning red and then green when energized.
Note: placing the battery holder in with the incorrect orientation will not damage the system. It
simply will not start.

Taking a Measurement
1) When the system has completed its boot up sequence, the home screen will display an
Android application called Pb200i. To access the application:
a. Swipe the “lock”icon on the home screen to the right (Fig. 7).
b. Select the Pb200i application by touching the app on the LCD (Fig. 8).
c. Enter the password assigned by the Compliance or Safety officer using the
keyboard provided (Fig. 9).
d. Accept the acknowledgment that you understand that the system produces
radiation when the lights are on (Fig. 10).
e. Select “Test”(Fig.11).

2) The software is designed to open and close the shutter of the system, exposing the
radioactive source. To open the shutter, certain conditions must be met. These
conditions are:
a. The proximity button must be depressed.
b. The trigger must be pulled.
Once these conditions are met, the shutter will open. This will cause the LEDs on the left and
right side of the system to turn on, emitting a red light. If anyone of the conditions stated above
are not met during the measurement process, the shutter will close immediately and the LEDs
will shut off. Once the shutter is opened, there is a maximum time limit of five minutes that the
shutter will remain open for, if all the above conditions are met.

The instrument should be flush against the object you are measuring so that the proximity
button is fully engaged. Use the foot stabilizer to balance the instrument directly against the

surface you are measuring (see figures 12,13). When the proximity button is depressed fully,
the green light will give the user a visual que indicating that the instrument is ready to take a
measurement.

When the measurement begins, you will notice the numbers on screen changing as it
calculates a result:

Once the measurement has been completed, the final result will be posted, the shutter will close
and the LEDs will turn off. Typical measurements in paint mode will take anywhere from one to
three seconds. Results in examples below are based off an action level of 1.0 mg/cm2.

Sleep function:The system will go to sleep after 30 minutes of inactivity. You may
press any button to wake the system back up again. **Be advised, a bug exists in the
version of code on the two RAD systems running the RAD safety application, where if
the system sleeps for too long, the LCD does not wake back up. The length of time to
create this scenario is unknown. If this happens, please remove the battery and restart
the system.
