Manual
Conforms to relevant Australian standards
Complies with European Directives
Do not dispose of this clamp meter as
unsorted municipal waste. Contact a qualified
recycler for disposal.
Warning and Precautions
• Avoid condensation on CO2 sensor
• Do not hold the meter close to faces in case
exhalation affects CO2 levels.
• Do not calibrate the meter in the air with
unknown CO2 concentration. Otherwise, it will
be calibrated as 400ppm by default and leads to
inaccurate measurements.
UNPACKING AND INSPECTION
Your shipping carton should include:
1 CO2-200 CO2 Meter
1 Adaptor
1 User manual
1 Plain white box
If any of the items are damaged or missing, return
the complete package to the place of purchase for an
exchange.

INTRODUCTION
Thank you for purchasing this CO2 meter. It measures
CO2 level, air temp., dew point, wet bulb temp. and
humidity and is an ideal instrument for indoor air quality
(IAQ) diagnosis.
Poor indoor air quality is considered unhealthy because
it causes tiredness, loss of ability to concentrate, and
even illness (ex. Sick Building Syndrome). IAQ monitoring
and survey, especially on CO2 level and air ventilation
become widely applied in public areas such as offices,
classrooms, factories, hospitals and hotels. It is also
suggested in regulations of industrial hygiene in some
countries. (Appendix)
With NDIR (non-dispersive infrared) sensor used, this
CO2 meter is stable in long term monitoring. And the
built-in relay for alarm output is especially useful in
ventilation control and HVAC system performance
verification.
Features
• Triple displays of CO2 level, temp. and humidity.
• Stable NDIR sensor for CO2 detection.
• Statistics of weighted averages (TWA & STEL)
• Visible and audile CO2 warning alarm
• Alarm output for ventilation control
• Battery and adaptor power supply
• ABC(Automatic Baseline Calibration) and manual
CO2 calibration
• USB PC connection

OPERATION
1. Plug in the adaptor and the meter turns on
automatically with a short beep. It performs
30 seconds countdown (Fig.1) for meter warm
up, then enters normal mode with current CO2,
temperature, and humidity readings displayed.
2. The meter starts taking measurements when
power on and updates readings every second. In
the condition of operating environment change
(ex. from high to low temp.), it takes 30 sec to
respond for CO2 sensor and 30 minutes for RH.
3. Press “p/DP/WB” to switch temperatures
display. The lower left display will cycle from air
temperature, dew point temp., and wet bulb
temp. (Fig. 2)
4. Press “MNX/AVG/q” to see the minimum,
maximum, and weighted average readings.
Each press of it displays MIN, MAX, STEL, TWA in
sequence and returns to normal mode. In MIN and
MAX modes, it shows the minimum and maximum
readings of CO2 on main display, and of AIR/DP/
WBT temperatures and humidity on the lower
displays. In STEL and TWA modes, the main display
shows the weighted average of CO2 readings for
the past 15 minutes (STEL) and 8 hours(TWA), but
the lower displays are the current AIR, DP/WB
temperatures and humidity readings.
NOTE:
• If the meter is turned on for shorter than 15
minutes, the STEL value will be the weighted
average of readings taken since power on. Same
for TWA values appear before 8 hours.
• It takes at least 5 minutes to calculate STEL and
TWA. The display shows “----” during the first 5
minutes from power on (Fig. 3).
