3.2 Device operation
3.2.1 Turning on the device turn, testing and calibration
3.2.1.1 To turn the device ON, press the ON/OFF button 8 (Figure 2). The device enters the
test mode after it is turned ON or after the batteries are replaced. While the device is in this mode,
Red-LED and Yellow-LED are flashing in turn. After completion of the test mode the device can go
either to the calibration mode (if batteries were replaced), or to the mode of detection of exceeding
the preset thresholds. The device is ready for operation, when Red-LED and Yellow-LED are
switched OFF and Green-LED is switched ON.
3.2.1.2 While in the calibration mode, Red-LED and Yellow-LED are flashing
simultaneously. The calibration of TSM is performed in this mode. To calibrate the TSM, mount
the filter 14 (Figure 2) (included in SET-O) to the input connecting pipe 2 and turn its cover 16 to
the “Open” position. After that enter the calibration mode by replacing the batteries. The
calibration will be completed in no more than 2 min. The calibration completion is indicated by
Red-LED and Yellow-LED switching OFF. After the calibration completion, turn the filter cover
16 to the “Close” position, remove the filter 14 and bring it into the right position in the SET-O.
The device automatically enters into the mode of detection of exceeding the preset thresholds
of the gamma radiation DER and concentrations of toxic substance vapors.
Caution! If the calibration process was interrupted (the device was turned OFF
before the simultaneous flashing of the Yellow-LED and the Red-LED stopped), then in
the mode of detection of exceeding of the set thresholds of gamma radiation and
concentrations of toxic substance vapors the Red-LED will be flashing with 10 s
intervals. In this case to ensure detection thresholds, perform calibration until both the
R-LED and the Y-LED are off.
3.2.2 Device operation in the mode of detection of exceeding the preset thresholds of the
gamma radiation DER and concentrations of toxic substances vapors
3.2.2.1 While in the mode of detection of exceeding the preset thresholds of the gamma
radiation DER and concentrations of toxic substances vapors, the device can be used for the
simultaneous detection of toxic substance vapors (TSV) in air and the detection and location of
gamma radiation sources (GRS).
The device operates with the parameter values set by the manufacturer (3.2.3.1). To use
other parameters, it is necessary to set the other values (3.2.4).
The device automatically enters the mode of detection of exceeding the preset thresholds
of GRS and TSV after the completion of the calibration mode.
3.2.2.2 Detection of GRS and TSV
To achieve the maximum sensitivity during the GRS detection, the device should be
placed in such a position that the calibration direction indicated in Figure 2 coincides with a
direction to a scanned object.
The detection efficiency is dependent on the proximity of the device to an examined
object (thing, car, person, etc) and velocity of its movement along the object.
To achieve the maximum sensitivity during the TSV detection, the input connecting pipe
of the toxic substance module should be completely opened.
3.2.2.3 Location of gamma radiation sources
When a gamma radiation source is detected, it can be located.
To locate the source, the device should be at no more than 10 cm distant from the
scanned object. The velocity of the device movements along the scanned object should not
exceed 1cm/s. As the device moves closer to the gamma radiation source, a rate at which
Yellow LED is flashing and audio tone is repeated will increase.
When the maximum rate of audio signals is achieved, a continuous audio tone is
produced. The source can not be located better.
