CARBON DIOXIDE
MONITOR
PTH-5 USER MANUAL

Please read this manual carefully before using the product and keep it properly.
Thank you for purchasing the carbon dioxide monitor PTH-5! This product uses a carbon dioxide sensor based on the principle of non-dispersive infrared absorption, which can accurately measure the concentration of carbon dioxide in the air with a concentration range of 0 ppm to 5000 ppm.
Long-term inhalation of high concentration of carbon dioxide by the human body can easily induce hypoxic suffocation . This product can keep you away from these troubles. It is suitable for cars, baby rooms, homes, Offices and other densely staffed occasions.

4. Button
   Button| Operation| PTH-5
   ---|---|---
   A| press and hold for 3 seconds| Power on / off
   Press| Switching temperature units between C & T
   B| press and hold for 3 seconds| Set screen state: screen backlight off after 10 minutes / stay on
   Press| Backlight on/off
   A+B| Press at the same time| Place it in a ventilated place, press the A and B buttons together for manual calibration. The process is completed after 200 seconds countdown.

Description:

1. Power-saving function: In the screen backlight off state, the indicator status is the breathing light effect, and the user can wake up the backlight by short pressing any button. After the backlight is awakened each time, if there is no button operation continuously, the product will automatically turn off the screen backlight after 10 minutes , But the indicator light still detect the current air quality.
2. First time, press and hold the B button for 3 seconds, the screen enter into backlight-off state after 10 minutes. Second time, press and hold the B button for 3 seconds, the screen enter into backlight stay on state. It cycle afterwards.

Alert

Whether the Carbon dioxide value exceeds the standard is indicated by the expression icon and indicator light, as shown in the following table:

When the measured value is between 0-700ppm, the Carbon dioxide value belongs to the safe range;
When the measured value is between 700-1500 ppm, the Carbon dioxide value belongs to the warning range and needs close observation;
When the measured value exceeds 1500ppm, the Carbon dioxide value exceeds the standard and must be open the window for ventilation.
You can also directly judge whether the formaldehyde value exceeds the standard through the indicator light. The following is the comparison table of indicator light color and its meaning:
