The input connecting pipe 2 of TSM (Fig. 1) with a cap 16 is located on the top cover of the device. When the device is operated the cap is taken off the input connecting pipe 2 and fixed adjacent to the connecting pipe at a plug 1. During the device calibration, the filter 15 involved in the set of spare parts and tools (SET-O) is screwed on the connecting pipe 2. The Red-LED Ph 5, RedLED Arc 6, Yellow-LED 4, Green-LED 7 , ON/OFF button 9, window 8 of the IR interface and device serial number 3 are located on the front panel of the device. The clip 14 is placed on the back side of the device. The Fig. 1 shows how to mount and remove the clip. The Geiger-Muller module (GMM) is located in the bottom part of the device. The housing 12 involving batteries and the audio alarming device (AAD) 13, as well as the cap 11 of the output connecting pipe are fixed to the lower cover of the device. The GMM effective center 10 is shown in Fig. 1, and an arrow points a direction of calibration. 2.4.2 Principle of the device operation 2.4.2.1 The principle of the device operation is based on comparison of the registered DER value with the set DER threshold and the registered concentration value of toxic substance vapors with the set threshold value of concentration level. The dose equivalent rate is registered in the mode of detection of exceeding the set thresholds of gamma radiation using GMM based on the Geiger-Muller counter. Exceeding of air concentrations of toxic substances vapors relative to set threshold level is detected by using a TSM based on an ionizing chamber with 63Ni beta-source. An analyzed air is pumped through the chamber using a micropump. The detection modules are operated by a microprocessor controller with a built-in analogue-digital converter (ADC). The device is powered by two AA batteries with a nominal voltage of each battery 1.5 V, or by 220V AC through a 12V/1,1A power supply unit and transformer or by 9-36V car battery by using a transformer from the delivery set of the device. 8 1 - plug for fixing the cap of the input connecting pipe of TSM; 2 – input connecting pipe of TSM; 3 – window with the device serial number; 4 – Yellow-LED; 5 –Red-LED Ph; 6 – Red-LED Arc; 7- Green-LED; 8 – input window of the IR interface; 9 – ON/OFF button; 10 – GMM geometric center; 11 - cap of the output connecting pipe; 12 – housing with batteries; 13 – window for the audio alarming device; 14 – clip; 15 – filter, 16 – cap; 17– filter cover Fig. 1 9 2.4.2.2 A block diagram of the device is presented in Fig. 2.

An infrared interface (IrI) 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 Operation modes The device has the following operation modes: - test mode; - calibration mode; - TSM blowing mode; - mode of detection of exceeding the set thresholds of gamma radiation and concentrations of toxic substance vapors; - mode of communication with PC. 10 In any operation mode the device controls over the battery voltage (see clause 3.2.5). 2.4.3.1 Test mode The device enters this mode every time when it is turned ON or the batteries are replaced. While in this mode the microprocessor controller provides for testing and diagnostics of the main device modules. If all tests are passed successfully the device enters the detection or calibration mode. 2.4.3.2 Calibration mode The device enters this mode automatically after the test mode is finished if the batteries were replaced before its turning ON or after the long (more than 3 s) pressing of the ON/OFF button. While in this mode, the device performs the calibration of the TSM channel (blow through the ionization chamber, autocalibration of "zero" of the TSM channel). After calibration is finished, the device automatically goes into the mode of detection of exceeding the preset thresholds of gamma radiation and concentrations of toxic substance vapors. 2.4.3.3 TSM blowing mode The device can enter this mode in case that the TSM calibration process takes more than 2 minutes because of the effect of high toxic substance vapor concentration or the ionizing chamber is contaminated. In this mode the ionizing chamber is blown out. If the device stays in this mode more than 5 minutes it is required to clean the gas systems and the ionizing chamber. In case that blowing passes successfully the device returns automatically to the calibration mode. 2.4.3.4 Mode of detection of exceeding the preset thresholds of gamma radiation and concentrations of toxic substance vapors While in this mode the device performs a continuous and independent control of the radiation and chemical conditions. While in this mode the device produces light and audible signals as follows: - "Chemical alarm" (Red-LED Ph or Red-LED Arc is flashing) when the threshold value of the TSM is exceeded; - "Radiation alarm" (Yellow-LED is flashing) when the preset DER threshold is exceeded. The light alarms are accompanied by audible alarms if these are enabled in the mode of communication with PC. The device provides for a possibility to record and store the history of operation (DER values with set time intervals, alarms, i.e. exceeding of the set threshold value of DER and concentration of TSM), and values of preset parameters in the non-volatile memory. 2.4.3.5 Mode of communication with PC The device performs an exchange of information with PC using WINDOWS 98/2000/NT/XP through the infrared channel. An IR adapter and an exchange protocol compatible with the IrDA interface are used. While in the mode of communication with PC the following operations may be performed: - the device can be registered to a user; - to store a time when the device was received and returned by a user; - to read information from the device memory; - to change the following device parameters: - the set DER threshold; - to disable audio alarms; - the time interval to store the history of operation; 11 -to store and transmit to PC the history of the measurement of the photon radiation DER, records about exceeding the preset thresholds of gamma radiation and concentrations of toxic substance vapors. 2.5 Marking and sealing The logo and name of the manufacturer, name of the device, IP code, and the device serial number are inscribed on the device. The "Radiation danger" sign with the source type and its activity is marked on the bottom side of the device housing. A seal that prevents an unauthorized opening of the device is placed in the faceplate of the device in the screw groove. 2.6 Packing The device is put into a pasteboard box together with its documents and SET-O. 12 3 USE OF THE DEVICE 3.1 Preparation for use 3.1.1 General information 3.1.1.1 When buying the device please check the delivery kit according to clause 2.2.1 and perform the device operation check up according to clause 3.1.4. The device should not be subjected to severe mechanical shocks, any strong chemicals and solvents and open fire sources. 3.1.2 Safety precautions 3.1.2.1 During the device assembling, calibration, repair and maintenance when radioactive sources are used, all the requirements and regulations ensuring the radiation and sanitary safety should be observed. 3.1.2.2 The beta radiation source IBIRRZN-63-IIa, 7016-056-41805307-2002 which is included in the ionization chamber contains the 63Ni radionuclide of 0.6 GBq activity. This source is located inside of the ionizing chamber in the device housing. 3.1.2.3 The beta radiation DER does not exceed the natural background level at any point of the outer surface of the package with the device inside. The device design excludes the possibility of the access to the source during device operation. Therefore it is not necessary to take any additional safety precautions actions for radiation security. 3.1.3 Preparation for operation 3.1.3.1 Before using the device, please read this operating manual carefully. 3.1.3.2 Take the device from the package. 3.1.3.3 Insert the batteries into the battery compartment 12 (Fig. 1). 3.1.3.4 Remove cap 16 from the connecting pipe of the ionizing chamber 2 and the output connecting pipe 11. 3.1.3.5 Screw cap 16 on the connecting pipe at a plug 1, and put cap 10 of the output connecting pipe into SET-O. 3.1.3.6 When starting the operation after the long storage of the device, it is required to clean the gas system and the ionizing chamber in according to clause 4.4 of the present Manual. 3.1.3.7 Calibrate the device according to clause 3.2.1.2. After calibration is finished the device is ready for operation. 3.1.4 Device operation check up 3.1.4.1 After device calibration according to clause 3.2.1 it is necessary to check up the device operation. After calibration is finished, the Green-LED should light constantly and a sound of the working micropump should be heard. To check up the chemical channel operation, bring the Phosphorous imitator from the SET-O (set of the spare parts and tools) to the input of TSM. The light alarm (Red-LED Ph) should flash and audio alarm will be heard. Remove the imitator. The light and audio alarms will be switched OFF in no more than 30 s. After this bring the Arsenic imitator from the SET-O to the input of TSM. The light alarm (Red-LED Arc) should flash and audio alarm will be heard. Remove the imitator. The light and audio alarms will be switched OFF in no more than 30 s. Caution! When checking up the chemical channel operation with the imitator from the SET-O in enclosed space it is necessary to provide the blowout from the output connecting pipe outdoors (exhaust ventilation). Before the iterative checking up it is necessary to blow out the gas system through the TSM filter for 10-20 minutes. To check up the radiation channel, bring a radioactive source (its energy range is from 0.06 to 3.0 MeV) close to the GMM geometrical center (Fig. 1). The light alarm (Yellow-LED) will flash and audio alarm will be heard. Remove the source. The light and audio alarms will be switched OFF. 13 To turn the device OFF, press the button 9. The Green-LED and the micropump should be switched OFF. 3.2 Device operation 3.2.1 Turning on, testing and calibration of the device 3.2.1.1 To turn the device ON, press the ON/OFF button 9 (Fig. 1). 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 Ph, Red-LED Arc 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 Ph, Red-LED Arc and Yellow-LED are switched OFF and Green-LED is continuously ON. 3.2.1.2 While in the calibration mode, Red-LED Ph, Red-LED Arc and Yellow-LED are ON simultaneously. The device enters this mode if the batteries were replaced or the ON/OFF button was pressed for a long time. The calibration of TSM is performed in this mode. To calibrate the TSM, mount the filter 15 (Fig. 1) (included in SET-O) to the input connecting pipe 2 and turn its cover 17 to the “Open” position. The calibration will be completed in no more than 2 minutes. The calibration completion is indicated by Red-LED and Yellow-LED switching OFF. If after 2 minutes the device goes to the TSM blowing mode, one need to wait for not more than 5 minutes while completion of this mode. If the device stays in the TSM blowing mode more than 5 minutes, it is required to clean the gas systems and the ionizing chamber of the device according to clause 4.4 and to turn on the device once again. After the calibration is finished, turn the filter cover 17 to the “Close” position, remove the filter 15 and bring it into the right position in the SET-O. The device automatically enters 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 was 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 Operation in the mode of detection of exceeding the set thresholds of gamma radiation and concentrations of toxic substance 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 (see clause 3.2.3.1). To use other parameters, it is necessary to set the other values (see clause 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 or after completion of test 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 Fig. 1 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 GRS When a gamma radiation source is detected, it can be located. 14 To locate the source, the device should be at no more than 10 cm distance 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. N o t e - The location of GRS is only possible in the only case when DER emitted by a source at a distance of 10 cm is higher than 1 µSv/h, as the minimum settable threshold equals to 1 µSv/h. 3.2.3 Parameters setting 3.2.3.1 The preset parameters The device is shipped with the preset parameters as follows: - time intervals for storage of current photon radiation DER values in the non-volatile memory of the device - threshold photon radiation DER value - threshold for detection of vapors of - organophosphorus substances (sarin, soman, V-gases, etc. ) - arsenic-containing substances (lewisite) - audio alarm device 60 min 1 µSv/h 5⋅10-5 mg/l 2⋅10-4 mg/l enabled 3.2.4 Operation in the mode of communication with PC 3.2.4.1 The device is in the mode of communication with PC during 15 s after it is turned ON. To repeat a communication, it is necessary to turn the device OFF and then to turn it ON again. To use the mode of communication with PC is possible only after the application program supplied on CD is installed on PC. An IR adapter and the application program PM2010M (supplied on CD) should be used to operate with the device in the mode of communication with PC. Minimum requirements to a computer and its software: - Pentium; - 16 Mb RAM; - Windows 98/NT/2000 XP (small font); - 2 Mb free on the hard disk and an adequate space available to install the database; - 800x600 resolution of a monitor. Connect the cable of the IR adapter to a communication port of the personal computer or use the PC with a built-in IR adapter. To install the application program, use the CD with software included in the delivery kit. The Help file describes how to run the application program. To communicate with PC, turn the device ON and place it for 15 s near the IR adapter at a distance of 10-20 cm, the IR interface window should face the IR adapter. The information exchange between the device and PC will be carried out in some seconds. Follow the instructions given in the application program for further activities. 3.2.5 Control over the battery voltage 3.2.5.1 In any mode of operation, the device continuously controls over the batteries voltage, that is indicated by a solid light of Green-LED. If the batteries voltage drops below the permissible level, Green-LED flashes. The batteries should be replaced. If the batteries are not replaced, the device microprocessor switches OFF the micropump and the device will operate in the only mode of detection of gamma radiation sources, and the TSM will not operate (GreenLED is flashing). If the batteries voltage drops even lower, the device will be turned OFF. 15 3.2.6 Use of external power supply unit To use the external power supply of PM2010M: - unscrew the housing with batteries 12 with the help of screwdriver (Fig.1); - place the converter 3 (Fig.3) observing the polarity; - fix the converter with a screw.
