Ⅰ. Introduction
Carbon Dioxide Monitor adopts high-quality gas sensors,which displays
safety and reliability with accurate measurement and stable performance.
It has excellent sensitivity and repeatability, easy to use and maintain, and
meets the requirements by safety monitoring in industrial site for high
reliability of the equipment. The shell is made of high-strength engineering
plastics and compound non-slip rubber, dust and explosion-proof, with high
strength and smooth handfeel.
Carbon Dioxide Monitor is widely used in petroleum, chemical,
environmental protection, metallurgy, refining, gas transmission and
distribution, biochemical medicine, agricultural research,etc.
To know and understand relation between carbon dioxide concentration
and human physiological reaction:
350-450ppm: the same as general outdoor environment
350-1000ppm: fresh air and; smooth breath
1000-2000ppm: turbid air; feel sleepy
2000-5000ppm: headache, sleepiness, dull, heartbeat accelerating and
lightly nauseous and be unable to concentrate
Over 5000ppm: severe hypoxia, permanent brain damage,coma and
even death
Ⅱ. Safety instruction
For your safety, please read this manual before operation.
:This operation may induce physical hazard to users. Please be careful.
:This operation may cause damage to the instrument.Please be careful.
Warning!
If there is explode accident happening:
Cut off all the potential gas resource.
Keep the rescuing area ventilated and no potential combustible gas
existing.
Switch off all the power connection.
Evacuate all the people in the area.
Report to the authorities immediately.
In daily work, please keep the work environment ventilated,for good

the instrument enters into the countdown interface (for the sensor takes
about 20 seconds to stabilize).After the countdown is over, the main
menu screen will appear (Figure 1).
(2) The current date and time are displayed on the upper left corner.If the
time is incorrect, enter the settings interface to set.
(3) The battery level is displayed on the upper right corner. When the
remaining power is low, the battery indicator will turn red. When the ower
level is detected to be too low, the instrument will start 10s countdown for
automatic shutdown.The countdown second will be displayed on the left
side of the battery indicator. After the countdown is over, the instrument
will automatically shut down.
(4) There are four icon options in the main menu, namely, real-time measure-
ment, checking record, alarm setting and system setting;
(5) Functions of Buttons:
1) : When the icon is selected, touch the icon and it will turn
unselected, touch it again to go back to the first icon (unslected).
2) : If an icon is not selected, touch the icon and it will
become selected. Touch it again to select the next icon by pressing

shows the maximum,minimum and average value,where the average value
which is the value measured in the last 4 minutes; the right side shows the
high and low alarm values, and the middle shows real-time values.
(2) When checking concentration, if the concentration value is greater than the
low alarm value, the instrument will trigger low alarm state. If the concentra-
tion is greater than the high alarm value, the instrument will trigger high
alarm state;
(3) In alarm state, Danger icon shows up; otherwise, Safety icon is displayed.
(4) In the alarm state, if the alarm is triggered, an alarm will be issued and the
alarm will be issued when the alarm is high.The alarm in high alarm state
shows more urgency and faster frequency than that of low alarm state.
(5) The alarm has two forms, light flashing alarm and sound alarm, which can
be turned on/off in the alarm setting.
(6) The lower left corner of the screen shows the lower limit of the range, the
lower right corner shows the upper limit of the range, the lowermost triangle
indicates the color of realtime value.
(7)

month, day, hour, minute;if auto storage is on, the measured data will be
automatically saved according to the set recording interval. If not, it will not be
stored automatically; if the auto off is on, if there is no button operation within
the set shut-down time, it will automatically shut down. If auto off is not on,it will
not automatically shut down; in the backlight setting, there are two levels of
backlight brightness;restoring factory setting can restore all para meters except
for date and time in the instrument to factory state.

Ⅸ. Charging function description
When the power is insufficient or the voltage cannot be turned on due to
undervoltage, please charge in time and charge it.During the charging
process, the alarm light will flash and the meter will no longer detect the gas
concentration and display it dynamically.Indicates the number of battery
packs. When the number of battery packs is full and no longer changes
dynamically, charging is completed.When you can unplug the charger, the
meter can be used normally.
Ⅹ. Warnings and Precautions
Improper operation or environment may cause accidents.
1. The instrument is strictly prohibited from collision, falling from high places
or violent vibration.
2. If there is gas of high concentration, the instrument may not work properly.
3. Please operate and use strictly in accordance with the instruc tions,
otherwise it may result in inaccurate test results or damage to the
instrument.
4. Do not store the instrument in the following environments:
a. Places that may have water or heavy dust.
b. The instrument must not be stored and used in environments that contain
corrosive gases (such as salt or sulfur in high concentration, etc.).
c. Air with other gases or chemicals.
d. Places of high temperature, high humidity or direct sunlight, including
environments of too high and low temperatures, high humidity,
electromagnetic fields, and strong sunlight.
5. Cleaning of the instrument's surface:
a. The window of the sensor must be kept clean. If it is dirty, the measurement
will be inaccurate.
b. Please wipe it gently with a clean, soft cloth dampened with water (do not
use alcohol, diluent, etc. to clean the case, especially for the LCD window.).
6. If the instrument breaks down, please contact our professional personnel
to repair it. Other people shall not change components and wiring.
Warning:
Prohibit charging or disassembling batteries in an explosive environment!
