Operating Instructions
Initial Setup : When first unboxing, plug in the unit to the included Micro USB (or one of your own) to almost any cell phone charger or USB power source. If successfully connected, 3 things will happen while booting up:
3 LEDs flash one by one
Chart display shows the current software version & “Warm Up”
Main display shows a countdown from 10
Once the countdown is complete, your product is ready to use. No initial setup or calibration is needed.

Trend Chart
The trend chart (1) displays the past readings for any of the three parameters (CO2/Temp/RH). There are 4 modes that can be toggled by using UP key: CO2, TEMP, RH, and Cycle (automatically cycles through CO2/Temp/RH), as shown below
Trend Chart Zoom
Below is a table that show the available Zoom Levels for all parameters CO2/Temp/RH, as well as the duration of each division for corresponding Zoom Levels:
Zoom Level (Time Span) (15) | Time Per Division(13) | |
1m (minute) | 5m/div | |
1h (hour) | 5m/div | |
1d (day) | 2h/div | |
1w (week) | 0.5d/div | |
Auto Cycle Zoom | Cycle |
Using DOWN will toggle the available Zoom Levels for each parameters. Note that in addition to the Zoom Levels for each parameter, there is an option that will automatically cycle between the Zoom Levels. This can be achieved just by pressing DOWN until icon(14) appears at the bottom left of the chart.
Max/Min
At the top right corner of the display, there are two numerical indicators: Max (2)and Min (5). As the Zoom Level is changed, the Max and Min values will reflect the maximum and minimum values on the chart of the selected parameter(CO2; Temp and RH). At startup, the unit will automatically display values for CO2.
