General Introduction
 
 
Indoor Air Quality (IAQ) is measure for the quality of air in interiors, the comfortable indoor environmental quality can make people feel fresh, work efficiency and good for the health. The CO2 concentration is the important factor of good indoor air quality. People breath in oxygen and breath out CO2, nowadays people often close the windows to avoid noise and enjoy the comfort living and working environment provided by air-conditioning systems, which results in the fact that the indoor concentration of CO2 is far higher than outdoor average. With the high CO2 concentration and non- proper ventilation, people will feel headaches, dull, drowsiness, lose of concentration and correspond to the high levels of dust, chemicals and bacteria in the air.

Customizing Settings
 
 
   When the power has been connected, The ZGw063RY CO2 monitor will begin to work. In order to meet your
   personal requirements, it is advisable to set up the customizing parameters.
   WarmUp:
   It lasts approximately 1min before WARM UP disappears; all MODE functions will not response during warm up.
Temperature (ºC/ºF) and Ventilation Rate:
  1. Press Up/Down to choose Temp or Vent Rate.
  2. Press Up, then orderly display Temp (ºC) → Temp(ºF) → Vent Rate l/p/s → Vent Rate cfm/p; Press Down, the display order is opposite.

Note: Temp ºC refers to Temperature in Celsius;
Vent Rate l/p/s is Liter/Person/Second, Vent Rate cfm/p is Cubic Feet Minute/Person.

Using the MUTE function:

  1. Press MODE, the MUTE icon flashes simultaneously.

Calibration & Warranty

Notice:

Before calibrating, you need to obtain standard gas or semi-standard gas, there
  are 3 ways to get standard gas.
  Method A: use CO2 in office/building
  - Use two meters (One is the device for calibration. The other one is a calibrated
  (new) one.
  - Use ambient room gas for calibration in office, waiting at least 10min, until the CO2 reading doesn’t change
 
 

 (Notice: user must not breathe toward the ZGw063RY, CO2 from the user will affect   the reading of ZGw063RY)

 
- Use the reading of the new device as the standard reading.
- Calibrate device by the Cali Mode instruction.
  Method B: use CO2 outsides
  - Use ambient room gas for calibration outside. Wait at least 10min, until the CO2
 

reading stabilizes.

   (Notice: user must not breathe toward the ZGw063RY, CO2 from the user will
    affect the reading of ZGw063RY)
-

Use 380~420ppm as the standard reading.

- Calibrate the device by the Cali Mode instruction.
  Method C: use standard CO2 in the bottle
  - Pump the standard CO2 gas(0~1000ppm, flux = 0.1~0.2 liter/min) into the
  ZGw063RY from the Gas Entry Hole, waiting about 2~3min.
  - Calibrate the device by the Cali Mode instruction.
