Chapter 2: System overview
2.1 Main Features
The PM 2012M/PM2012MA are simply-to-operate and reliable instruments in shockproof cases.
The two control buttons are of big size to allow the operator to use protective gloves.
The instruments measure the ambient dose equivalent rate
( )
10*
•
Η
and the ambient dose
equivalent Н*(10) of gamma- and X-ray radiation.
The PM2012MA model differs from the PM2012M model in the extended
measurement range of the dose equivalent and the lower main relative error of the
dose equivalent rate measurements (refer to Section 2.2), all the other parameters
being the same.
The PM2012MB model differs from the PM2012M in the lower main relative error
of the dose equivalent and dose equivalent rate measurements, in the extended
measurement range of dose equivalent and opportunity of data transfer via USB
with PC and via Bluetooth channel with smartphones.
The unit also detects vapors emitted from chemical warfare agents (CWA): organophosphorus
compounds (sarin, soman, V-gases) and arsenic-containing compound (lewisite).
If the preset thresholds of the radiation levels (the dose equivalent rate, the dose equivalent),
or/and of the CWA concentration are exceeded, the instrument alerts by audible and visual
alarms.
The unit can operate as long as 150 hours from a fully charged battery. The OLED display,
together with the color coded LED bars and messages, along with audible and visual alerts,
provide all relevant data to the operator.
The operation history is saved in the non-volatile memory of the unit and can be transferred to a
PC by infrared link for data viewing and programming.
Instrument Operation Conditions:
−ambient air temperature from -10 °Сto +50 °С(from 14°F to 122°F);
−ambient air relative humidity up to 98 % at 35 °С;
−atmospheric pressure from 84 kPa to 106.7 kPa;

2.4 Instrument Design
The instrument is a monoblock, which encloses two independent modules:
- gamma-radiation detector module (Radiation Detector Module) containing a Geiger-
Mueller counter;
- chemical warfare detector module (CWA Module) including an ionizing chamber with
Ni-63 beta source, and a micro pump.
The unit contains also appropriate electronics (with a nonvolatile memory) that controls over the
unit operation and stores the operation history.
The instrument (Figure 2.1) has two control buttons (7 and 8) and a rotating head (2) that allows
the operator to change the operating modes of the CWA Module.
The analyzed air enters the unit via the inlet (1) and exits it via the outlet (11).
The display (6) together with two color LEDs bars (3 and 3'), along with the audible alert device
(4) provides all relevant data to the operator.
The infra-red (IR) port (5) enables the data exchange between the unit and PC.
The lid (10) closes the battery compartment.
The instrument can be operated using AC adapter or DC power supply connected with the port
(9). In its turn, PM2012MB can be also operated using the USB cable.

2.5 Principles of Operation
The Radiation Detector module continuously measures the ambient dose equivalent rate
( )
10*
•
Η
and the ambient dose equivalent Н*(10) of gamma- and X-ray radiation and the dose
accumulation time.
If the preset thresholds of the dose rate or/and the dose are exceeded the unit produces audible
and visual alarms (on display).
When the CWA Module is activated, the ambient air is pumped through an ionizing chamber by
a micropump, and CWA vapors in air are monitored. To separate two types of CWA
(organophosphorus compounds and arsenic-containing compound) the polarity of voltage signals
is determined.
If the preset level of organophosphorus compounds (sarin, soman, V-gases) is exceeded, the
instrument produces an audible signal and displays a visual signal on the yellow LEDs bar.
If the preset level of arsenic-containing compound (lewisite) is exceeded, the instrument
produces an audible signal and displays a visual signal on the red LEDs bar.
The operation history is saved in the non-volatile memory of the unit and can be transferred to a
PC by infrared link for data viewing and programming.

Chapter 3: Preoperational Procedures
3.1 Battery installation
The unit comes without battery installed.
CAUTION!
Install and replace the battery when the CWA module is switched off! (refer to
section 3.3.)
To install the battery unscrew the lid of the battery compartment (10) (Figure 2.1), insert the
battery observing its polarity (the "+" contact must be facing inward); put the lid back.
Figure 3.1 – Battery installation
After the battery is installed, the instrument turns on automatically (except the CWA module).
The instrument continuously monitors the battery voltage and displays the battery sign with the
analogue scale in the upper right corner.
If the battery is fully charged, all five marks are displayed.
In case of critical discharge (the battery voltage drops below 1.23 V), two or one marks are
displayed, the battery sign blinks (2 times per second), audible alarm becomes quieter, the
micropump speed is gradually slowing, and then the micropump turns off. The battery should be
replaced.
If the battery is not replaced, the CWA module will be turned off automatically.
If the battery voltage drops below 1.1 V, the instrument turns off completely.
To extend the battery life, display becomes dark in about 20 sec. To activate it press
any control button (refer to section 3.3).

17
3.2 AC adapter and DC power supply
The unit can be also operated using the AC adapter. Open a rubber cap protecting the port (9)
(Figure 2.1) and connect the adapter with the adapter jack.

3.4 Checking instrument operation and functionality
Before operating the instrument, it is advisable to perform the procedures described
below.
3.4.1 Checking the Radiation Detector Module
To check the operation and functionality of the Radiation Detector module, turn on the
instrument; after the tests are completed, place a gamma source of 50 - 200 kBq activity (energy
range of 0.06 - 3.0 MeV) near the gamma detector geometrical center marked on the left side of the
instrument (Figure 3.5). The instrument will display the measured dose rate value (Figure 3.3).
When the measured dose rate value exceeds the preset threshold, an audible alarm will sound.
Remove the source. The audible alarm should terminate in 30 seconds.
Figure 3.5 – The mark of the geometrical center of the gamma detector
3.4.2 Checking the CWA Module
3.4.2.1 Calibration
To activate the CWA module turn the rotating head (2) (Figure 2.1) in the direction shown by the
arrow to match the

mark on the head and the
∆
mark on the unit case.
The CWA module enters the calibration procedure and the unit displays "CHEM: CALIBRATION"
(Figure 3.6), and a specific sound of the working micropump will be heard.
Figure 3.6 – Calibration procedure screen
While in this operating mode the instrument calibrates the CWA module, i.e. performs the
ionization chamber blowing and the calibration of the module "zero".

20
The calibration continues about 2 min, and then the unit displays “CHEM: SEARCH ON”. It
means that the calibration is completed and the instrument is ready to detect the CWA.
Figure 3.7 – Calibration completion screen
If the calibration fails during about 2 min due to a high CWA concentration or a high pollution
of the ionization chamber, the instrument automatically enters the ionization chamber blowing
mode and displays “CHEM: BLOWING”.
Figure 3.8 – Blowing mode screen
This mode ensures the additional blowing of the ionization chamber. The instrument
automatically returns to the calibration mode when the blowing is successfully completed.
CAUTION!
If the instrument continues blowing longer than 3 min, clean the gas lines,
ionization chamber and micropump, refer to section 5.2.
3.4.2.2 Checking with the CWA simulator
After completing the calibration procedure (the unit displays "CHEM: SEARCH ON", Figure
3.7), switch the unit to the CWA detection mode: turn the rotating head in the direction shown by
the arrow to match the mark on the head and the
∆
mark on the unit case. The unit displays
"CHEM: SEARCH":
