KDF-CO2-AQ1 Mini 3 in 1 NDIR CO2 Desktop Monitor

Device Overview

Thank you for selecting KDF-CO2-AQ1 desktop CO2 monitor. KDF-CO2-AQ1 CO2 monitor is smart, compact, and easy-to-use. In addition to measuring the CO2 concentration, KDF-C02-AQ1 can also measure the ambient temperature and the relative humidity (CO2+Temp.+RH). This device is developed to detect the presence of CO2 in ambient air and helps people to take care of Indoor Air Quality. KDF-C02-AQ1 can be widely used in the office building, school, exhibition hall, shopping mall, meeting room, fitness center, restaurant, and other public places where personal comfort and healthy are important.

Features

• Dual Beam NDIR (Non-Dispersive-Infrared) technology is being used to measure CO2 concentration and improve the 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 darken the LCD backlight during the period from 22:00 pm to 6:00am.
• 7-color backlight for options: white → turquoise → blue → purple → red → yellow → green.

Warnings

• Please take off the AC power adapter and store it well when this CO2 monitor left idle for long.
• This CO2 monitor is for home use, not suitable for certifying the test results.
• If use this CO2 monitor for testing, KDF-CO2-AQ1 does not guarantee the test results.

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 power on, the bars on the LCD are decreasing 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 backlight 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; 800ppm~1,400ppm is yellow; >1400ppm is red.
• 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 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.

°C/°F switch: Long press Select key ( 3 ) to switch °C/°F.
Real-time: Set “24 Hour /12 Hour(AM/PM)”, the default is “24 Hour”, please see the section 5.3 to learn how to switch “24 Hour /12 Hour(AM/PM)”.

Setting:
Long press 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.
* Note: During the setting process, the device will return to the main screen after 20 sec of idle time.
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)
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)

Real-time:

Set “12 Hour(AM/PM)/24 Hour ” by pressing Select key ( 3 ).
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.

Note: Complete the settings(hour-minute) to save the real-time values.

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)

Calibration: Press and hold Mode key ( 2 ) and then press Select key ( 3 ) together. When the CO2 calibration value flashes on the LCD, it means that the calibration mode has been entered. (Figure 5) Press Select key ( 3 ) to adjust the CO2 calibration range: 350ppm~600ppm, the interval is 10ppm. Press Mode key ( 2 ) to confirm the value, then “CAL” icon will flash on the LCD. Press Select key ( 3 ) to select setting modes in sequence: CAL (background calibration) → CLr (clear the background calibration value) AbC (automatic background calibration).

Note: During the operation, if the device is left idle for 20 sec or the user presses and holds Mode key ( 2 ), the device will return to the main screen.

CAL: After confirming the calibration value, the background calibration is the first mode. When “CAL” icon flashes on the LCD, press Mode key ( 2 ) to perform the background calibration and start to count down 10 minutes (Figure 6). If you want to interrupt the process, press Mode key ( 2 ) to stop it. (Figure 7) When the timer reaches zero, the calibration is completed and “dn” icon is displayed on the LCD. (Figure 8)

• (Figure 7)
• (Figure 8)

CLr: When “CAL” icon flashes on the LCD, press Select key ( 3 ) 1 time to select “CLr” (Figure 9), and then press Mode key to confirm it. The “dn” icon is displayed on the LCD, indicating that the background calibration value has been cleared. (Figure 10)

AbC: When “CAL” icon flashes on the LCD, press Select key ( 3 ) 2 times to select “AbC” (Figure 11), and then press Mode key to confirm it. The “on” icon is displayed on the LCD, indicating that the automatic background calibration is turned on. (Figure 12)
Note: AbC is recommended to re-open in a well-ventilated environment. This function is not recommended for greenhouses, wine cellars, confined or poorly ventilated spaces, which will affect accuracy.

HISTORY: Bar graph displays indicate the status of CO2 records up to 24 hours (Figure 13)

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