CO LEVELS AND STANDARDS
ppm Symptoms and applicable standard
0-1 Normal background levels

Maximum indoor air quality level:
Maximum allowable concentration per ASHRAE Residential standards 62-1989 for
living area.
25 Maximum limit 8 hrs of continuous exposure per California OSHA Workplace
standards.
35 Maximum 8 hrs average exposure level per US OSHA workplace standards.
50 Maximum concentration for continuous exposure in any 8 hrs average level per
OSHA standards.
100 Remove employees from enclosed space if the CO concentration exceeds 100ppm
per OSHA exposure limit.
200 Mild headache, fatigue, nausea and dizziness w/i 2-3 hrs.

400 Frontal headache, life threatening after 3hrs. Maximum concentration in flue gas
per EPA and AGA.
800 Dizziness, nausea, convulsions, death w/i 2-3 hrs.
1600 Nausea w/I 20 min; death w/I 2-3 hrs
OPERATION
1. Power on/off
Press• �to turn on and off the meter. When meter is power on, the preset alarm value and
current air temperature will be blinking on the LCD.
Meter will perform Self-Test for 15 seconds. A beep after the self test indicates that the•
meter is ready to use.
A 25 ppm
26 C
IMPORTANT:
It is recommended to turn on the meter in an area free of CO since high CO level may cause
failure in passing Self-Test.
2. Alarm setting
The meter alarm is preset to 25ppm to warn about possible danger.•
User can adjust the alarm level by choosing one. The available CO gas levels: 25, 30, 35, 45,•
50, 70, 100 and 200ppm.
Release the pushbutton to select the preferred value. The meter will return to Self-Test•
mode in a few seconds.
3. Measurement
The meter detects the existence of CO in the environment and displays the reading in ppm.•
It also indicates the maximum value (at lower side of the LCD) of all readings.
Reset the maximum value by pressing• pushbutton for two seconds in measuring mode.
4. Backlight
Press pushbutton to turn on and off the backlight.

5. Low battery indicator
Appears on the LCD when battery voltage is low.
6. Auto power off
The meter turns itself off automatically after 15 minutes of non-operation.
CALIBRATION
To enter the calibration mode, turn off meter and press �+ pushbuttons simultaneously
for 2 seconds. It will show a blinking ppm on the upper display and calibration value ”0” at
lower side. Now the meter is running 0ppm calibration as default.
0ppm calibration
The preset calibration value is 0ppm. Put the meter in an area free of CO and enter the
calibration mode. It calibrates automatically. The LCD is now displaying a blinking ppm value
at the upper side which slowly runs down to 0 or minus value, then stops blinking when the
calibration is completed. This takes about 10 minutes.
Note:
Don’t be alarmed if high ppm or minus value shows up when entering calibration mode. It will
go down and approach to 0 in seconds. The erratic readings are caused by electromagnetic
interference (EMI) in the environment, such as computers or cell phone. It is required to have
the meter away from these types of interference, otherwise the calibration may take much
longer time or never complete.
100ppm/500ppm calibration
For other standard calibration, press1. pushbutton and hold to select the calibration
value. (0, 100, 500ppm).
Place the meter into the sealed box filled with standard gas (e.g. 100ppm/500ppm) for 152.
minutes. Then the Calibration will be done automatically.
Check if the reading meets calibration value. If it does, the calibration is well completed. If3.
not, repeat the procedure.
TROUBLESHOOTING
Device cannot power ON
Check if the time since power on is over 300 mS.1.
Make sure the batteries are in good contact and correct polarity.2.
Replace the batteries and try again3.
Display disappears
Check whether the low battery indicator shows before display disappears. If so, replace the
batteries.
Calibration failure
Check if the low battery indicator shows before calibration. If so, replace a new battery and1.
try again.

8
Make sure the standard gas is correct.2.
E 2.: The value is underflow.
E 3.: The value is overflow.
E 4.:The value is “error”because of some original data.
E 31.: A/D failure, return the meter to the dealer for repair.
E 33.: Some measurement circuits failure, return the meter to the dealer for replacement or
repair.
E 35.: Self-Test failure. Turn on the meter again in other area free of CO.
Sensor failure. Return the meter to the dealer for repair.
PRECAUTIONS
Keep the meter away from electromagnetic interference (EMI) which may cause erratic1.
readings.
Recovering time is required when meter exposed to high level CO. The longer the exposure,2.
the longer recovering time is needed.
Self-Test after power on is to test the sensor and circuit condition.3.
