point, all the symbols are displayed on the screen. You hear a beep and the
device goes into normal operating mode. A 60-second countdown appears on
the screen indicating that the CO₂ sensor is being initialised. The CO₂ values are
then shown in the display.
When using the charging cable, the battery inside the device is charged. If the
power supply is interrupted, the device switches to battery mode or it can be
operated directly with the built-in battery. A fully charged battery lasts about five
hours of continuous operation with the backlight on and at maximum level.
5.1 Battery
You can check the battery level in the display at any time by looking at the
battery level symbol.
When the voltage of the built-in battery is low, the battery symbol flashes on the
screen. The product turns off the backlight, carbon dioxide detection function,
etc. to ensure that the time function works continuously.
While the battery is charging, the battery symbol is displayed continuously. Once
the battery is fully charged, the symbol disappears.
