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 CO2/Temp/RH, as well as the duration of each division for corresponding Zoom Levels:

SD Card For Logger:
The device will record data logger by SD card while it existed. Its can record Date, Time, CO2, Tempereture, RH, user can check and download logger by SD card reader. User can setting logger interval time by enter 'ADV' mode. The interval time can be set as 5/30/60/300/600 second.

CRR Function:
Predicts the remaining CO2 supply and reminds the user to add or replace the CO2 generator. For example, hydrocarbon fuel, fermentation (sugar + yeast), etc.

Typical test conditions, unless otherwise specified: Ambient Temp =23+/-3°C, RH=50%-70%, Altitude=0~100 meter
