WTC01 Instruction Manual
activities and good ventilation environment. It is not applicable to agricultural greenhouses, farms,
warehouses and other places.
Description:
According to the change of carbon dioxide concentration, if it rises within one hour or more than or
equal to 100 ppm, the arrow points up; if it drops within one hour or more than or equal to 100 ppm, the
arrow points down; if it does not exceed 100 ppm within one hour, the arrow points flat.
According to the current CO2 concentration value, there are four levels of ICONS:
: 400~600 ppm;
: 601 ~ 1000 ppm;
: 1001 ~ 1500 ppm;
: 1501~2000 ppm;
flash: 2001 ppm and
above
when the co2 concentration is greater than 1500PPM, the screen will display
to remind the user
to open the window for ventilation.
when the co2 concentration is greater than 2000PPM, the screen will display
to remind users to
pay attention to safety.
Temperature, humidity, carbon dioxide concentration detection frequency is 5 seconds.
Touch " " to switch backlight level, a total of three levels (high - medium - low - off).
When the built-in lithium battery voltage is low, there will be a low power symbol "
" flashing on the
screen, the product will turn off the backlight function, carbon dioxide detection function, etc. to ensure
the continuous operation of the time function.
In the process of lithium battery charging, the battery symbol "
" is displayed scrolling, and the
battery symbol is hidden after full.
It is recommended to use DC power supply for a long time, and try not to use the built-in lithium battery
to low power.
During carbon dioxide detection, avoid product vibration and direct blowing of the sensor by strong
winds, which may cause deviation of the carbon dioxide detection value.
