Device Overview
Thank you for selecting the CO2Meter RAD-0302 - IAQMini CO2 Monitor. The RAD-0302 IAQ Mini is a low cost, compact, and easy-to-use indoor
air quality monitor with the ability to measure Carbon Dioxide (CO2), Temperature, and Relative Humidity concentrations in indoor air
environments. In addition, the RAD-0302 is developed to detect the presence of CO2 in ambient air to help the user ensure overall improved
indoor air quality in environments such as homes, office buildings, classrooms, exhibition halls, shopping malls, fitness centers, commercial
buildings, or anywhere where personal comfort and overall well-being isvital.
Features:
V□Dual Beam NDIR technology isused to measure, monitor and track CO2concentrations toimprove long term stability.
V□The Large LCD clearly displays the CO2concentration, temperature, relative humidity and real-time clock.
V□3-color back light (green / yellow / red) gradually changes color with CO2concentration.
V□“HISTORY” with 3 emotions indicates the status of CO2records up to 24 hours.
V□“ECO” saving power function darkens the LCD back light during the period from 10:00pm to 6:00am.
V□7-color back light for options: white turquoise blue purple red yellow green.
Warnings:
V□Please take off the ACpower adapter and store it well when this CO2monitor isleft idle for long.
V□This CO2 monitor is for home or commercial use, not suitable for safety applications or data logging.

Operation Instructions
1. Power on and Measure:
Connect the USB cable to a PC ora USB towall adapter to power on the device. After powered on, the bars on the LCD will decrease by degrees
during warm-up. The device will start to measure CO2 concentration, ambient temperature and relative humidity after warm-up.
2. Backlight Display Mode:
"Auto"auto backlight isthe default mode. Press Mode key (○2 ) to display the current back-light mode and then press Mode key (○2 )to select
setting modes in sequence: Auto AL on OFF. After selecting the mode, itisthe confirmation mode. You do not need to press any key to
confirm it.
2.1 Auto: The backlight color varies with the CO2concentration. <800ppm isgreen, good status;950ppm~1,400ppm isyellow, okay status,
>1400ppm isred, poor status – requires ventilation.
2.2 AL: The alarm level isexceeded and the backlight isdisplayed in red. The default alarm level is1,400ppm. Please follow the alarm level setting
method to adjust the alarm level.
2.3 on: The LCD backlight is always on. It is only LCD backlight, without any prompt function. The backlight color depends on the color you select.
(please see the setting of COL).
2.4 OFF: Turn off all backlight functions.
3. Setting:
Press and hold Mode key (○
2) to enter the settings. And then press Mode key (○ 2) to select setting modes in sequence: COL (LCD backlight color)
AL (alarm level setting) Real-time ECO (energy-saving mode). Press Select key (○
3) to adjust the parameters.
3.1 COL: The default LCD backlight color is white. A total of 7 colors are optional. The color order is white turquoise blue purple red 
yellow green. (Figure 1)
3.2 AL: The default alarm setting is 1,400ppm. The alarm value can be adjusted from 400ppm to 3,000ppm (the interval is 100ppm). (Figure 2)
3.3 Real-time:
3.3.1 Set “12 Hour (AM/PM)/24 Hour” by pressing Select key (○
3).
3.3.2 The default real-time setting is 0:00(24 Hour Clock). The setting sequence is hour minute. After setting "hour", press Mode key (○
2) to
set "minute" (the interval is 1 hour / 1 minute) (Figure 3). Press Select key (○
3) to adjust the parameters. Press and hold Select key (○ 3)
to quickly set the parameters.
3.4 ECO: The default ECO setting is “OFF’. Press Select key (○
3) to select “on’. After ECO mode is turned on, the LCD backlight will be dark
during the period from 22:00 pm to 6:00am for saving power. (Figure 4)
(Figure 1) (Figure 2) (Figure 3) (Figure 4)
Note: During the setting process, the device will return to the main screen after 20 sec of idle time.
4. °C/°F switch: Press and holdSelect key (+)to switch °C/°F.

1. Plug in and power your device outside.
***Note: Do not breathe directly on your device during the calibration process.
***Note: Do not place the device in direct sunlight.
2. Allow your device to sit outside for 3 - 5 minutes to allow CO2 levels to adjust appropriately.
3. Press and hold the Mode key (MODE) and then press Select key (+) together. When the CO2 calibration value flashes on the LCD, it means
that the calibration mode has been entered.

6. HISTORY:Bar graph displays indicate the status of CO2 records up to 24 hours (Figure 13)
(Figure 13)
6.1 "0h" bar graph displays the current CO2concentration and it is updated with new records every 10 seconds.
6.2 "-3~-24" bar graphs display the average CO2concentration and it is updated with new records every 10 minutes.
"-3" is the average CO2concentration of the latest 3 hours.
"-6” In past 6 hours, the average CO2concentration of the first 3-hour.
"-12" In past 12 hours, the average CO2concentration of the first 6-hour.
"-18" In past 18 hours, the average CO2concentration of the first 6-hour.
"-24" In past 24 hours, the average CO2concentration of the first 6-hour.
E.g. It is now 12:00 noon on 12/01. “-3” = 09:00~12:00 (12/01); “-6” = 06:00~09:00 (12/01); “-12” = 00:00~06:00
(12 /01) ; “-18” = 18:00 ~24:00 (11/30) ; “-24” = 12:00~18:00 (11/30)

4. Press Select Key (+) to adjust the CO2 calibration range 350ppm ~ 600 ppm, the interval is 10ppm. Set the calibration value to 400ppm.
5. Press the Mode Key (MODE) to confirm the value, then "CAL" icon will begin to blink on the LCD.
6. Press the Mode Key (MODE) to begin calibration. "CAL" will stop blinking. "St" will show up in the lower left section of the display and the
10-minute countdown will begin.
7. Once the calibration is complete, the display will show a "dn" in the place of the "St". This will indicate that the calibration is complete.
***Note: The device will return to the main screen after 20 sec of idle time.
