Trend Chart Display
The below chart displays the past readings for any of the three parameters
(CO2/RH /TEMP). There are 4 modes that can be toggled by using key: CO2, TEMP,
RH, and Cycle(automatically cycles through CO2/TEMP/RH).
Press will toggle the available Zoom Levels for each parameters.(Minute/Hour/
Day/Week)
Below is a table that shows the available Zoom Levels for all parameters CO2/RH/ TEMP,as well as the duration of each division for corresponding Zoom Levels:
| Zoom Level (Time Span) | Time per Division |
|---|---|
| 1M(minute) | 5sec /div |
| 1H(hour) | 5m/div |
| 1D(day) | 2h/div |
| 1W(week) | 0.5d/div |
Max/Min
At the top right corner of the display, there are two numerical indicators: MAX and MIN.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, RH and TEMP).
Main Menu Functions
The Main Menu functions can be actived by pressing . Pressing / once will
bring up the main menu, with an underlining flashing bar indicating the
current choice.
To select the function, press when it is underlined by the flashing bar. Note that after 30 seconds if nothing is pressed, the Main Menu will disappear and the device will revert to the normal state.
| Function | Description |
|---|---|
| ALARM | 
When ALARM display , an audible alarm will sound if the CO2 level exceeds
preset CO2 alarm value; means MUTE.
PLANT| 
Select number 0 to enter human mode. 0 is defaulted as human mode,
unchangeable. The preset Low and high alarm are 800 and 1200ppm. Enter “ADV”
to adjust them if necessary. In plant mode, it allows user to select between
types of plants for optimal setting by using / cycles through 1~9. See number
references with corresponding alarm settings in High and low alarms in Page
14.
LOG| 
This function allows the user to see historical data records.
CALI| 
Before calibration, run this device for at least 20 minutes with windows open
or in outdoor environment with portable battery source to reach an atmosphere
with 400ppm CO2. Wait till the CO2 reading is stable, follow above steps for
calibration. After calibration leave it 10 minutes before normal use.
ºC / ºF| 
Use this function to toggle between Celsius ( C ) and Fahrenheit ( F ) for the
temperature display.
ADV| 
Use this function to set high and low alarm values of human mode (0) as well
as the first option of plant mode (1). High and low alarms for options 2-9
under plant mode are not adjustable. See details in Page 14. (Appendix)
