INTRODUCTION

Thank you for purchasing this portable CO2 meter. The

meter 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)

The portable CO2 meter uses NDIR (non-dispersive

infrared) technology to ensure the reliability and long

term stability. It’s useful in verifying HVAC system

performance and air ventilation control

Features

• Triple displays of CO2 level, temp. and humidity.

• Stable NDIR sensor for CO2 detection.

• Statistics of weighted averages (TWA & STEL)

• Backlight for working in dark area

• Audile CO2 warning alarm

• Battery and adaptor power supply

• Easy manual calibration on CO2 and humidity

• USB PC connection

OPERATION

1. Press “POWER/SET” to turn instrument on and off.

At power up, it emits a short beep and performs

30 seconds countdown for meter warm up, then

enters normal mode.

2. The meter starts measurement when power

on and update 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 “DP/WBT” to switch temperatures

display. The lower left display will cycle from air

temperature, dew point temp., and wet bulb

temp. (Fig.1)

Fig.1

4. Press “HOLD” to freeze the readings, “HOLD”

icon is displayed on the left top of LCD. All current

readings are kept unchanged, except STEL and

TWA. Press “HOLD” again to cancel data hold

function.

5. Hold down “MODE/p”for more than 1 second to

activate and cancel backlight.

6. Press “MAX/MIN” 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.

5

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.2).

Fig.2

• While all readings are held unchanged, STEL

and TWA will keep updating every 5 minutes.

7. The instrument emits beeps (Abt.80dB) when CO2

level goes over the set limit and stops when any

key (but “POWER“ key) was pressed or readings

fall below the set value. It beeps again when value

goes over the limit. Restart the meter if beeper

can’t be stopped.

Auto Power Off

The meter turns off automatically after 20 minutes of

inactivity. To override the function, hold down “POWER

/ SET” and ”HOLD” for 2 seconds to turn on the meter

until “n” appears.

6

Setup

The advanced setup mode lets you customize your meter.

2 types parameter are available.

P1.0: CO2 alarm threshold setting

P3.0: Temperature unit setting

P1.0 CO2 alarm threshold setting

Hold down “POWER/SET” under normal mode for more

than 1 sec to enter set up mode. To exit setup, press

“CAL/ESC” in P1.0 or P3.0.

When entering setup mode, P1.0 and “AL” are displayed

on the LCD (Fig.3). Press “ENTER” to go into P1.1 for

setting CO2 alarm threshold. The current set value will

be blinking on LCD (Fig.4). Press “p”to increase the

value or “q”to decrease. Each press tunes 100 ppm and

the alarm range is from 100 to 9900ppm. When the

preferred alarm value is set, press “ENTER” to save the

setting or “ESC” without saving and return to P1.0.

Fig.3 Fig.4

P3.0: Temperature unit setting

Press “p“or “q”in P1.0 to access P3.0 for setting up

temperature scale. Press “ENTER” and it goes into P3.1

with blinking °C or °F current set on the lower left

display. To switch °C or °F, press “p“or “q. Then press

“ENTER” to save the setting or “ESC” without saving and

return to P3.0.

Calibration Mode

CO2 calibration

1. Place the meter in an outdoor area with well

ventilated air. Turn on the meter and hold down

“CAL” and “p” simultaneously to enter CO2

calibration mode. 400ppm and “CAL” are blinking

on the LCD while performing calibration (Fig.5).

Fig.5

2. Wait about 5 minutes until it stops blinking and

the calibration completes automatically and back

to normal mode.

3. To abort the calibration, turn off the meter at any

time.

Humidity calibration

1. Plug the sensor probe into 33% salt bottle. Hold

down “CAL” and “q” under normal mode to

enter 33% calibration. “CAL” and calibrating

value (32.7% if at 25°C) are blinking on the LCD

with current temperature at the left. Meter is now

calibrating, and will finish in about 60 minutes

when “CAL” and humidity value stop blinking.

2. After 33% calibration, plug the sensor probe into

75% salt bottle, then press “ENTER” to enter 75%

calibration. “CAL” and calibrating value (75.2%

if at 25°C) are blinking on the LCD with current

temperature at the left. Meter is now calibrating.

Wait about 60 minutes until blinking stops, then

calibration is completed and it returns to normal

mode.

3. Users can also calibrate either point. To calibrate

33% only, press “ESC” and exit when 33%

calibration is completed. To calibrate 75%

only, press “p” or “q”within 5 minutes while

initializing 33% calibration. To abort calibration,

just turn off the meter.
