WELCOME
Thank you for purchasing the FALCON-II indoor air quality monitor. The FALCON-II
is an easy to use, portable, monitoring device for monitoring trends that pertain to
indoor air quality.
The FALCON-II is equipped with integral CO2 and temperature sensors to aid in
verifying readings providing an indication of air quality. Information readings are
temporarily written to built-in memory. The instrument may be hand-held or will
easily stand on a flat surface.
The FALCON-II instruments are manufactured to provide good value to the end
user. Calibration and repair is available at our manufacturing facility and through
some of our authorized and trained distributors.
If after reading through the manual, you have any questions, please do not hesitate
to contact our service department for technical support.

5.0 OPERATION
The Falcon-II is a rugged, hand-held, battery powered instrument for measuring and
displaying Carbon Dioxide (CO2) and Temperature. It operates from internal alkaline
batteries or it’s own (supplied) wall adapter.
5.1 OPERATING MODES
MODE DESCRIPTION LCD DISPLAY
ALTI Compensate for the effect
of pressure changes by
inputting the appropriate
altitude of the location
where the instrument is
being used.
ALARM Alarm when CO2 concen-
tration exceeds one
threshold alarm. Alarm
level can be changed
through the keypad /
menu. The audible alarm
can be switched on/off
through the keypad / menu
when the speaker icon
flashes
OUTSIDE Modify the concentration of
outside CO2 for defining
the ventilation rate
CALI Calibrate the sensor when
the reading deviates from
the actual CO2
concentration
DATA LOGGER Show CO2 and
temperature records in the
past 24-hours
MAX-MIN Show the Max and Min
readings before being
cleared off or before
switching off

5.2 DETAILED OPERATING INSTRUCTIONS
PowerOn
Press the 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 instrument has
been powered up, the CO2 reading will show after 15 seconds of warm up.
WarmUp
It takes approximately 1-minute before “WARM-UP” disappears from the LCD. All
the functions will not respond during the warm up period.
UserMode
After warm up, the device will stabilize and display the normal CO2 reading in the
upper part of the LCD) and remain visible at all times. Temperature and Ventilation
Rates will be shown in the lower portion of the LCD. 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: “TempºC ->
TempºF -> 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

5.22 OPERATION - MODE ADJUSTMENT, CONT’D…..
3.0 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, readings should be taken 2~3 hours after
occupancy has stabilized in a space or at a peak in daily CO2 concentrations.
With indoor air quality control, CO2 value is an indicator of ventilation rate. 400 ppm
(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), to show OUTSIDE CO2 and PPM flashes. Press Up/Down ( ④/
③) to adjust the reading.
3.3. Press the Enter ( ②), save the setting and return to the User Mode. After
modification, the VENT Rate will change.
4.0 CALI Mode
The CO2 monitor has been calibrated at the factory and should be recalibrated
every 12-months with a specified concentration of CO2. Sensor drift usually occurs
in linearity. To perform calibration, follow the steps below.
4.1. If battery icon shows low power, replace batteries before attempting to
calibrate or use AC adapter.
4.2. Press the Mode button ( ⑤), until CALI flashes.
4.3. Press Enter ( ②), “CALI” is shown on the display
4.4. Adjust the lower display to ambient CO2 value by pressing the Up/Down ( ④/
③) Button.
4.5. Press Mode button ( ⑤) for more than 10 seconds. “CALIBRATING” flashes.
Calibration will be finished after 5-minutes and the LCD will indicate
“PASS”. If LCD indicates “FAIL”, repeat the calibration.
