LED will light when CO2 concentration is between the alarm1 level and the alarm 2 level.
Using the CALI (calibration) Mode:
1. Press MODE, The CALI flashes.
2. Press ENTER, the CALI icon on the display.Adjust the lower display to the ambient CO2 reading by
Up/Down button.
3. Press MODE for more than 10sec, CALIBRATION flashes. Calibration will be done automatically after 3
minute and the LCD will display “Pass” or “Fail.” If it shows “Fail,” please try again.
Setting the Datalogger Mode:
1. Press MODE, DATALOGGER icon flashes.
2. Press ENTER, the reading of CO2, RH and Temperature show on the LCD.
3. Press Up/Down to page up/down the reading. The numbers from 1 to 48 will display with CO2 reading
alternatively. If the LCD display with number “1”, it indicates the first datalogger with CO2,RH and
temperature reading,. The datalogger function can record 48 sets reading.
Remark: With the Built-in Datalogger,ZGw063RY can provide the past CO2,RH and temperature reading within
the past 24 hours. The log interval is 30 minutes per data. ZGw063RY is connected with power and
used for the first time, if the working time is more than 30 minutes, ZGw063RY will have CO2, RH and
temperature reading in datalogger, if the working time is less than 30 minutes, the LCD will display
“NULL” while using the datalogger function.
Using the MAX MIN Mode:
1. Press MODE, the MAX MIN flashes simultaneously.
2. Press ENTER, the reading of CO2, RH and Temperature show
on the LCD alternatively.
3. Press Up/Down and the “CLR” will flash on the LCD. Press Enter
to CLEAR the MAX and MIN record.
Note: With the Built-in MAX MIN mode, ZGw063RY can provide the Maximum and Minimum CO2, RH and
temperature reading record after the device is powered on. If users press up/down to clear the MAX and
MIN CO2 reading record, ZGw063RY will provide the new MAX and MIN CO2, RH and temperature
reading from that time.
Using the “RcFS” Mode:
1. Press MODE, The RcFS flashes simultaneously.
2. Press ENTER, the icon “no” shows on the LCD, Press the Up/Down to select the no/yes.
3.After selecting, press ENTER to save the changes.
Note: If the users set the data or calibrate the sensor wrongly. You can use the RcFS (Recover the factory
Setting) to come back to factory setting data, the datalogger with 48 sets of CO2,RH and temperature will
bewillbecleared.

Calibration
Note: 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: usermust not breathe toward the ZGw063RY, CO2 from the userwill 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: usermust not breathe toward the ZGw063RY, CO2 from the userwill 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.
