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).
