Monitor (CO
2
+Temp.+RH) Operating Instructions
Device Overview
Thank you for selecting ZGm27 desktop CO2 monitor. ZGm27 CO2 monitor is smart, compact and easy-to-use. In addition to measuring the
CO
2
concentration, ZGm27 can also measure the ambient temperature and the relative humidity (CO
2
+Temp.+RH). This device is developed to
detect the presence of CO
2 in ambient air and helps people to take care of Indoor Air Quality. ZGm27 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:
□V Dual Beam NDIR (Non-Dispersive-Infrared) technology is being used to measure CO
2 concentration and improve the long term stability.
□V The Large LCD clearly displays the CO
2 concentration, temperature, relative humidity and real-time clock.
□V 3-color backlight (green / yellow / red) gradually changes color with CO
2 concentration.
□V “HISTORY” with 3 emotions indicates the status of CO
2 records up to 24 hours.
□V “ECO“ saving power function darken the LCD backlight during the period from 22:00 pm to 6:00am.
□V 7-color backlight for options : white
à turquoise à blue à purple à red à yellow à green.
Warnings:
□V Please take off the AC power adapter and store it well when this CO
2
monitor left idle for long.
□V This CO
2
monitor is for home use, not suitable for certifying the test results.
□V If use this CO
2
monitor for testing, ZGm27 does not guarantee the test results.

Operation Instructions
1. 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 CO
2
concentration, ambient temperature and relative humidity after warm-up.
2. 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
à AL à on à 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 CO
2
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.
3. °C/°F switch: Long press Select key (○
3
) to switch °C/°F.
4.
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)”.
5. 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)
à AL (alarm level setting) à Real-time à 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.
5.1 COL: The default LCD backlight color is white. A total of 7 colors are optional. The color order is white
à turquoise à blue à purple à
red à yellow à green. (Figure 1)
5.2 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)
5.3 Real-time:
5.3.1 Set “12 Hour(AM/PM)/24 Hour ” by pressing Select key (○
3
).
5.3.2 The default real-time setting is 0:00(24 Hour Clock). The setting sequence is hour
à 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.
5.4 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)
