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.
1. Plug in USB Power Cable
LCD Display
1. CO2/TEMP/RH Chart
2. Max Reading of Chart
3. Min Reading of Chart
4. Micro SD Card
5. Audible Alarm On/Off
6. Date and Time
7. Temperature Reading
8. RH Reading
9. Main Menu
10. CO2 Reading
11. Zoom Level of Time(indicates the chart’s span of time)
Trend Chart
The trend chart (1) displays the past readings for CO2 and temperture and RH parameters.
That can be toggled by using DOWN key: CO2, TEMP, RH. As show below:
Trend Chart Zoom
Below is a table that show the available Zoom Levels for all parameters, as well as the duration of each division for corresponding Zoom Levels:
Zoom Level (Time Span) (11) | Time Per Division |
1MIN (minute) | 5sec /div |
1HR (hour) | 5m/div |
1Day (day) | 2h/div |
1WEEK(week) | 0.5d/div |
Using UP will toggle the available Zoom Levels for each parameters. Note that in addition to the Zoom Levels for each paramete.
Max/Min
At the top right corner of the display, there are two numerical indicators: Max (2)and Min (3). As the Zoom Level is changed, the Max and Min values will reflect the maximum and minimum values on the chart of the selected CO2 parameter. At startup, the unit will automatically display values for CO2.
Real Time
The real-time(6) display at the top right corner of LCD, user can adjust date and time by enter TIME mode.
SD Card For Logger
The device will record data logger by SD card while it existed. It’s can record Date, Time, CO2, Tempereture, RH, user can check and download logger by SD card reader.
