records, including: the results of measurements of the concentration of the controlled
components, temperature, pressure, the generalized fact of errors with the marking
"E1"..."E9", the fact of switching on the gas analyzer, the fact of discharge of the battery of
the power supply. Archive memory is read-only;

the specified volume new records are brought in a place of the first. It is possible to clear
(format) the memory of occasional measurements in the tuning mode of the gas analyzer.

record with all the recorded values in the record displayed on the screen.
2.15 Records from the archive memory and the memory of occasional measurements
can be sending to a personal computer via an infrared port.
3. Operation and description
3.1. The action of the gas analyzer on the channel for measuring the volume fraction
of methane (or methane-hydrogen mixture) is based on measuring the signal of a
thermocatalysis sensor. The gas analyzer uses a scheme of periodic supply of voltage to the
sensor with a period of 7.5 sec. and an algorithm for auto-correction of readings.
When the volume fraction of methane exceeds 5.0%, the gas analyzer automatically
switches to the regime of thermal conductivity measurement of the volume fraction of
methane in the range up to 100%.
The action of the gas analyzer on the channel for measuring the volume fraction of
carbon dioxide is based on the thermal conductivity method.
The action of the gas analyzer on the channels for measuring the volume fraction of
oxygen, carbon monoxide and hydrogen sulphide is based on the electrochemical
measurement method.
3.2 Appearance of the gas analyzer is shown in Figure 1.

Structurally, the gas analyzer is a protective shell of impact-resistant plastic,
consisting of a housing (1) and a cover (2), fixed to the body by four screws (3), one of
which is for sealing the gas analyzer with a special key. The cover has a rubber seal.
The housing has a measuring board and a power supply unit consisting of a Li-ion
battery and a protection board.
The power supply unit is located in the compartment of the lower part of the housing
and connect with the measuring unit by a two-wire cable with a connector.
At the request of the consumer, a radio module can be installed in the gas analyzer.
3.3 On the front surface, of the gas analyzer is located:
- display window (4);
- front shield (5);
- openings for supplying the gas mixture to the sensors (6), made in the form of a
grate consisting of inclined plates preventing direct moisture penetration onto the sensors.
A light-conducting zone (7) is located at the top of the cover to pass the signals of
four alarm LEDs, a battery charge LED, and signals from the infrared port.
3.4 There is a keyboard (8) with three buttons (9) on the side surface of the housing:
- scroll buttons - move through the menu items, change the digital value;
- execution buttons - switching on, switching off the gas analyzer, executing
commands.
WARNING! The commands are executed when the pressed button is release.
3.5 On the back of the case (1) there are:
- back shield (10);
- acoustic radiator window (11);
- self-cleaning contacts (12) for charging the battery of the power supply unit.
3.6 The gas analyzer does not have aggressive substances in its design and does not
require special disposal.

H2S
The lower area of the window displays the main menu:
« TURN OFF » - turn off the gas analyzer;
« SETUP » - go to setup mode;
“14.0 / BAEC” - 14.0 - software version, BAEC - checksum.
NOTE -the concept of "clean air" - atmospheric air in which there are obviously no
hydrocarbons.
4.1.2 Wait 5 seconds, ignoring the main menu suggestions.
The gas analyzer will pass to the testing phase (automatic zero or warm-up) and a
view window for M 02-01 with measurement channels CH4, O2, CO, H2S will appear on the
display.
The upper part of the window shows the current time, date, ambient temperature,
atmospheric pressure, battery icon and the degree of its charge (black field), as well
as the sign in the upper left corner in the case of installation in the gas analyzer radio
module.
The status line (immediately below the temperature) displays a message about the
action performed during the testing process.
In the lower field - the « TEST » indicator blinking during the test time and the
values of the set alarm thresholds (the first and second)

Upon its completion, the gas analyzer will go into the measurement mode and a view
window for M 02-01 will appear on the display in full configuration with a channel for
measuring hydrogen sulfide.
The gas analyzer readings from the channel for measuring the volume fraction of
methane should be set from «0.00%» to «0.05%», along the carbon monoxide measurement
channel from «0 ppm» to «2 ppm», through the hydrogen sulfide measurement channel
from «0 ppm» to «1 ppm », and the reading on the channel for measuring the volume
fraction of oxygen should be «20.8%» - «20.9%».

4.2 WARNING! When the operator performs actions that are not provided by the
logic of system the gas analyzer, a warning signal is given about the incorrect actions in the
form of a short intermittent light and sound signal.
5. Operating procedure
5.1 Gas analyzer operation in the measuring mode
To ensure the establishment of stable readings and a signal of an enabled state is 1
time per minute is fed a short light and sound signal. After that, you can start working with
the gas analyzer.
5.2 Alarm threshold concentration
When the threshold values of the concentration of the measured component are
reached, a light-sound intermittent signal appears, he display illumination turns on, and a
blinking icon of the reached first or second threshold level appears on the screen in the gas
code line, respectively, for M 02-01 with measurement channels CH4, O2, CO, H2S:
The alarm of the first threshold (light and screen backlight) can cancel by pressing
any of the buttons on the keyboard. At the same time, during the entire time of exceeding
the first threshold, the first threshold icon « 1▪» will display statically, as well as the current
value of the methane or oxygen concentration, respectively.
The alarm of the second threshold of each channel is not deactivated during the time
of exceeding the concentration of the set level.

5.3 Error alarm
When a malfunction appears on the screen in the process of operation, instead of the
concentration of the measured component, the symbol "E" (ERROR) "E1"..."E9" appears
on the screen than activated a continuous light and sound alarm, which lasts about 5
seconds.
In this case, it is necessary to turn off the gas analyzer and transfer to the technical
support service.
Do not use faulty gas analyzer.
5.4 Battery discharge alarm
When the battery of the power supply discharged below the permissible level,
warning signals about the discharge in the form of a light and sound signal (continuous
sound for (5 – 6) seconds with the illumination of the display screen) and a flashing contour
of the battery icon on the display screen.
After the warning signals, the gas analyzer can work for another 25 minutes at a
positive ambient temperature or 1 minute at an ambient temperature below (– 10 °C), and
then automatically turns off with a short-term light and sound signal at the time of
shutdown.
If you try to turn on the detector after it is disconnected due to the battery discharge
by the button, there will be an intermittent light signal during the hold button , but
the detector will not turn on. If necessary, you can try switching on again only after
charging the battery for at least 25 minutes.
5.5 Switching off the gas analyzer in the measurement mode
5.5.1 Press the button of the keyboard.
