Trend chart display
The trend chart displays the measured values to date for each of the three parameters (CO2/RH/Temp). There are 4 modes that can be selected with the button: CO2, TEMP, RH and “Cycle symbol” (-> alternates automatically between CO2/Temp/RH).
The available zoom levels for all the parameters CO2/RH/Temp and the increments in the different levels can be seen in the table below:
| Zoom level (time interval) | Time per increment |
| 1M (minute) | 5 sec/increment |
| 1H (hour) | 5 m/increment |
| 1D (day) | 2 h/increment |
| 1W (week) | 0.5 d/increment |
Max/MinTwo numerical indicators can be seen in the top right-hand corner of the display: MAX and MIN. When the zoom level is changed, the MAX and MIN values reflect the highest and lowest values in the table for the selected parameter (CO2, RH and Temp).
Functions in the main menu
To select a function, press while it is underlined by the flashing cursor. Note that if no button is pressed within 1 minute, the main menu disappears and the device returns to normal mode.
