ZG106 CO2and Temperature Monitor Operating Instructions
ZG106 is a portable, accurate handheld CO2monitor. In addition to measuring the CO2concentration, this device can also measure the
ambient temperature. It uses Dual Beam NDIR technology to improve the long term stability.
Features:
□
VThe built-in Data logger can store 48 sets of CO2and temperature in the past 24 hours; one log per 30 minutes.
□
VMax/Min mode can record the maximum and minimum concentration of CO2since the device has been last turned on.
□
VThe Alarm mode will sound at 1000 PPM, the ASHRAE limit. The Alarm Level can be modified, and the Alarm sound can be turned off.
□
VThe RCFS Mode can recover the original factory settings after the CO2device has been recalibrated, altered, or damaged.
MODE FUNCTIONS
There are several Modes which we can adjust the setting parameters. These modes are Alti Mode, Alarm Mode, Outside Mode, Ucal Mode,
Datalogger Mode, MaxMin Mode and rcFS Mode in sequence.
ALTI Compensate the pressure changes with appropriate altitude of location when measure.
ALARM Alarm while CO2concentration exceed one threshold, which can be modified.
The Alarm sound can be turn on/off while the “speaker Icon” flashes.
OUTSIDE Modify the outside CO2concentration, for defining the ventilation rate.
CALI Calibrate the sensor while the reading deviates from the actual CO2concentration.
DATALOGGER Show the past CO2and Temperature records in the past 24 hours.
MaxMin Show the Max and Min CO2reading before being cleared or powered off after PowerOn.
rcFS Recover the factory setting, if the device cannot show accurate reading.
OPERATION INSTRUCTIONS
■PowerOn
Press Power button (○
1) to turn on the device after placing 4 AA batteries into the battery holder or AC adapter plug into the DC socket.
Once power on, CO2reading will show after 15 seconds of warm up.
■WarmUp
It lasts approximately 1min before WARMUP disappears; all the functions will not response during warm up.
■UserMode
After warm up, the device will stabilize and display the normal CO2Reading (Upper Display) - remain visible at all times.

■Temp and Ventilation Rates (Lower Display)
The Up/Down button (○
4/○ 3) allows you to scroll through the Temperature and Ventilation Modes. When pressing the Up button, the
lower display will go through the following sequence: Temp°C -> Temp°F -> Vent Rate lps -> Vent Rate cfm/p
*Note: lps refers to Liter Per Second Per Person; cfm/p refers to Cubic Feet Per Minute Per Person

2.1.Adjust the alarm level
2.1.1. Press the Mode button (○
5), until ALARM flashes
2.1.2. Press Enter Button (○
2), “CO2” icon flashes
2.1.3. Press Up/Down(○
4/○ 3) to adjust the alarm level (≧1,000 ppm, interval is ±100ppm;＜1,000ppm,interval is ±50 ppm)
2.1.4. Press the Enter (○

3. OUTSIDE Mode
** Note: Ventilation Rate
Ventilate rate represents how much air is introduced into the indoor space from the outside. Low values indicate low ventilation rates and
potentially poor air quality. High levels indicate excessive ventilation and potential excessive energy usage. To obtain an accurate
measurement, reading should be taken 2~3 hours after occupancy has stabilized in a space or at a peak in daily CO2
concentrations. In indoor air quality control, CO2value is an indicator of ventilation rate. 400ppm (Parts Per Million) is the default CO2
concentration outside (according to ASHRAE: American Society of Heating, Refrigeration and Air conditioning Engineers)
3.1. Press the Mode button (○
5), until OUTSIDE flashes
3.2. Press Enter (○
2), show OUTSIDE, CO2and PPM flash
Press Up/Down (○
