– Block diagram of the device
The device operation algorithm provides for a continuous measurement, statistical
processing of measurement results, fast adaptation to variations of the radiation intensity (a
time of measurement is inversely dependent on the radiation intensity). An infrared interface
(IrDA) is used for an exchange of information between MPC and PC.
The device is equipped with a non-volatile memory used to accumulate and store
information.
2.4.3 Design of the device
2.4.3.1 The device is designed as a monoblock consisting of a toxic substances module
(TSM), a Geiger-Muller module (GMM), a printed circuit board of a microprocessor controller
(MPC) and a housing involving an audio alarming device (AAD) and batteries. The input
connecting pipe 2 of TSM (Figure 2) with a cap 15 is located on the top cover of the device.
When the device is operated the cap is taken off the connecting pipe 2 and fixed adjacent to the
connecting pipe at a plug 1. During the device calibration, the filter 14 involved in the set of
spare parts and tools (SET-O) is screwed on the connecting pipe 2. The Red-LED 4, Yellow-
LED 5, Green-LED 6 , ON/OFF button 8, window 7 of the IR interface and device serial number
3 are located on the front panel of the device.
The clip 13 is placed on the back side of the device. The Figure 2 shows how to mount
and remove the clip.
The Geiger-Muller module (GMM) is located in the bottom part of the device. The
housing 11 involving batteries and the audio alarming device (AAD) 12, as well as the cap 10 of
the output connecting pipe are fixed to the lower cover of the device.
The GMM effective center 9 is shown in Figure 2, and an arrow points a direction of
calibration.
