Product Overview

Thank you for selecting the RAD-0302 IAQ Mini CO2 Monitor. This 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. This can be used to monitor indoor air quality in the home, in the bedroom, offices, classrooms, fitness areas, or anywhere where personal comfort and overall well-being are vital.
Features

Dual Beam NDIR technology is used to measure, monitor, and track CO2 concentrations to improve long-term stability.
The Large LCD clearly displays the CO2 concentration, temperature, relative humidity, and real-time clock.
3-color backlight (green/yellow/red) gradually changes color with CO2 concentration.
“HISTORY” with 3 emotions indicates the status of CO2 records up to 24 hours.
“ECO” saving power function darkens the LCD backlight during the period from 10:00 pm to 6:00 am.
7-color backlight for options: white → turquoise → blue → purple → red → yellow → green.

Warning:

This CO2 monitor is not suitable for safety applications. The RAD-0102-6 or similar devices are required for CO2 safety.
Remove from power when storing for long periods of time.

Operation Instructions

Power on and Measure:
Connect the USB cable to a PC or a USB to wall 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.
Backlight Display mode:
“Auto” auto backlight is the 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, it is the confirmation mode. You do not need to press any key to confirm it.
2.1 Auto: The backlight color varies with the CO2 concentration. <800ppm is green, good status ; 950ppm~1,400ppm is yellow, okay status,

1400ppm is red, poor status – requires ventilation.
2.2 AL: The alarm level is exceeded and the backlight is displayed in red. The default alarm level is 1,400ppm. Please follow the alarm level setting method to adjust the alarm level.
2.3 on The LCD backlight is always on. It is only an 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.
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 the Select key (○3 ).
3.3.2 The default real-time setting is 0:00(24 Hour Clock). The setting sequence is hour → and minute. After setting “hour”, press the 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 6:00 am for saving power. (Figure 4) Note: During the setting process, the device will return to the main screen after 20 sec of idle time.
°C/°F switch: Press and hold the Select key (+) to switch °C/°F.
Calibration:
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 the Select key (+) together. When the CO2 calibration value flashes on the LCD, it means that the calibration mode has been entered. Press Select key (+) to adjust the CO2 calibration range 350ppm ~ 600 ppm, the interval is 10ppm. Set the calibration value to 400ppm.
4. Press the Mode Key (MODE) to confirm the value, then the “CAL” icon will begin to blink on the LCD. 5. 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. 6. 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.
HISTORY:
Bar graph displays indicate the status of CO2 records up to 24 hours (Figure

6.1 “0h” bar graph displays the current CO2 concentration and it is updated every 10 seconds.
6.2 “-3~-24” bar graphs display the average CO2 concentration and it is updated every 10 minutes.
“-3” is the average CO2 concentration of the latest 3 hours.
“-6” In the past 6 hours, the average CO2 concentration of the first 3-hours.
“-12” In the past 12 hours, the average CO2 concentration of the first 6-hours.
“-18” In the past 18 hours, the average CO2 concentration of the first 6-hour.
“-24” In the past 24 hours, the average CO2 concentration 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)
