1. General Information:
Thank you for purchasing Carbon Monoxide (CO)
meter. Read though the instruction manual before
operation for correct and safe usage. Please
store and retain this instruction manual for future
reference.
1.1 Safety Information - Read First:
Do not use the meter as a personal safety
monitor.
Learn and recognize the eects of CO
poisoning.
0-1 ppm Normal background levels.
9 ppm ASHRAE Standard 62-1989 for living areas.
35 ppm The average exposure level per U.S. OSHA
workplace standards.
50 ppm OSHA enclosed space 8-hour average level.*
100 ppm OSHA exposure limit.*
200 ppm Mild headache, fatigue, nausea and dizziness.
400 ppm Headache occur in 2.5 hours to 3.5 hours.
800 ppm Dizziness, nausea and convulsions.
Death within 2 to 3 hours.
* U.S. Department of Labor, Occupational Safety & Health
Administration (OSHA) Regulation 1917.24:
The CO content in any enclosed space shall be maintained
at not more than 50 ppm (0.005%). Remove employees from
enclosed space if the CO concentration exceeds 100 ppm
(0.01 %).

Explanation of Symbols:
Attention!
Refer to operation Instructions.
1.2 Introduction:
This instrument is a digital meter that measures
CO concentration and Temperature. Through
the easy to use control, the meter detects
the presence of Carbon Monoxide (CO) and
measures concentrations between 0-1000 parts
per million (ppm).
The digital meter indicates the presence of carbon
monoxide in two ways:
A reading on the LCD in ppm.
A beeper tone.
Alarm System:
The higher the concentration of CO, the faster
the beeper sounds.
Above 200 ppm, the beeper sounds
continuously, while the frequency of the tone
increases with the concentration of CO.
Above 1000ppm, the beeper sounds
continuously with the highest frequency of tone.
The LCD reads “OL” to indicate an out of range
condition.
Self-Test:
Install the batteries. To turn the meter on, press
the button. During the self-test, the display
counts down from “60” to “0”, while the meter
emits a beeper sound. If the meter passes the
self-test, the meter begins monitoring, and shows
a reading on the display.

If the meter does not pass the self-test, the LCD
shows “Err”, and does not take CO measurement.

4. Operation Instructions:
4.1 Power-Up:
Press the button to turn ON or OFF.
After Self-Test, if the meter detects between 0-3
ppm of CO, the LCD readings start decreasing
from the initial value to zero. The LCD shows
readings when the meter detects more than 3 ppm
of CO.
4.2 Selecting Temperature Units:
When the meter is rst powered on, the default
scale setting is set to the Celsius (°C) scale. To
change to Fahrenheit (°F) press the button.
Press again to revert to Celsius. The next time the
meter is turned on, the scale setting will be the
same as it was when you powered o last time.
4.3 Data-Hold Operation:
The present reading may be held on the display by
pressing the button. When the hold data is
no longer needed, release the data-hold operation
by pressing the button again.
When the meter is in the Data Hold mode, the
, and buttons are disabled.
4.4 SET ALARM Operation:
Press and hold the button for two seconds
to enter the CO high alarm threshold mode. The
setting range is from 0 to 1000 ppm (default is 35
ppm).
Press the ( ) button to increase the value
and press the ( ) button to decrease the
value. Release the button, the CO high alarm
point setting completion.
9
4.5 MAX Operation:
Pressing the button places the meter in the
MAX mode. Under this mode the maximum value
is kept in the memory simultaneously and updated
with every new data reading.
Pressing the button will display the MAX
indicator and the maximum value on the display.
This means that these data have been updated
in the memory and the reading is the present
temperature and carbon monoxide. Press the
button again to detect immediate value, the symbol
“MAX” ashes on the LCD.
To exit the MAX mode, press button for two
seconds.
4.6 Auto Power O:
By default, when the meter is powered on, it is in
the auto power o mode. The meter will power
itself o after 30 minutes if no key operation is
performed. To disable the auto power o feature,
press and hold the button and then power
on the meter, The auto power o symbol “
”will disappear to indicate that auto power o is
disabled.
4.7 Backlight On/O
The display backlight is switched on by pressing
the button. The backlight is switched o by
pressing the button again.
The meter will turn back light o if there is no push
button for 30 seconds.
4.8 Low Battery Condition:
When the battery voltage is under proper
operation requirement, the “ ” symbol will show
and ash on the LCD and the battery needs to be
replaced.
