INTRODUCTION
Thank you for purchasing MIC’s desktop CO2monitor.
It is used to measure CO2concentration,air temperature
and relative humidity with visible and audible alarms. This
CO2monitor is an ideal instrument for indoor air quality
(IAQ) diagnosis and HVAC system performance
verification.
Carbon dioxide (CO2) is a gaseous component of the
earth's atmosphere. The concentration of CO2in natural
ambient air is about 0.04% or 400ppm. With each breath,
human convert oxygen (O2) into carbon dioxide(CO2).
Although carbon dioxide is invisible and odorless, an
increased CO2-content makes is apparent because
human will notice increased fatigue and reduced
concentration.
FEATURES
1). Super large LCD simultaneously display of CO2level,
Temp., Relative humidity, Calendar (Y/M/D) and Time
(clock).
2). Six (6) smiley icons indicate indoor air quality levels
(350/450/700/1000/2500/5000ppm), easy to
understand CO2concentration.
3). Stable NDIR sensor for CO2detection
4). High alarm threshold is selectable.
5). Automatic Baseline Calibration (ABC) function
6). Audible warning for high CO2concentration!!
7). Dew point/ Wet bulb Temperature measurement.
(98138.98139.98538.98539 only)!
8). Heat Index /WBGT Temperature calculation.
(98538.98539 only)
9). Backlight function ( 98137.98139.98537.98539 only)

Plug with adaptor, meter turns on automatically . LCD
shows current CO2, RH & Temperature, Date and Time.
Six(6) smiley icons indicate the indoor air quality level
and appear on the top of first layer display

Note:
(1) Reset time whenever you turn on
the meter.
(2) Please use properly power

(b) TAKING MEASUREMENT
The meter starts the measurements when powered
on and updates reading every 6 sec.
Response time is 10 sec. for CO2, 2 Sec. for RH.
If the operation environment changes (ex. From high to
low temp.), it takes approx. 30 sec. for CO2sensor to
respond and approx. 30 minutes for RH into stable
measurement.
NOTE: Do not hold the meter close to your mouth
or any other source of CO2.
RECORDING MEASUREMENT (Model 9853X series)
While recording, the green LED light is flashing and
“Logging” icon is flashing on LCD,too. If you have set up
Hi, Lo alarm value, the red LED will be flashing while
detecting the value which exceeds the threshold.
( c) CO2 MODE
In the CO2Mode, press MODE button to switch CO2
display. The top layer of display will cycle 3 from CO2,

The unit automatically records maximum reading
and minimum reading after powered on.
b) RESET MAX/MIN:
Press MODE button to get MAX or MIN reading, under
MAX or MIN mode,
If current CO2reading is near MAX
or MIN, you will not be easy to see the difference.
Long press MODE button to reset

Note 2 (98138.98139.98538.98539 only):
a) TWA: ( Time Weighted Average 8 hours)
The meter keeps updating the reading every minute. If
the meter has been powered on for less than 8 hours,
the TWA value will be the weighted average of readings
since powered on.
b) STEL: (Short-Term Exposure Limit in 15 minutes
weighted average)The meter keeps updating readings
every minute. If the meter has been powered on for less
than 15 minutes, the STEL value shows the weighted
average of reading taken since powered on.

c) lps%: Liters Per Second per person.
d) cfm/p: Cubic Feet per Minute per Person
Assuming a conference room with Max. capacity of = 200
persons , If designed ventilation rate= 7 l/s person
The amount of ventilation required= 1,400 l/s (or 5-040!
CMH), if number of person is 70, the amount of ventilation
only need 490 l/s, we don’t need ventilate 1,400 l/s for
saving energy.

CALIBRATION
ABC (Automatic Baseline Calibration)
The monitor is designed with high accuracy NDIR CO2
sensor with ABC (Automatic Baseline Calibration) function
which establishes a baseline calibration to eliminate the
zero drift of the infrared sensor.
The ABC function is always “ON” when the meter is turned
on. ABC is designed to calibrate the meter at the minimum
CO2reading detected during 7.5 days continuous
monitoring (power on).
(e) Temperature unit (°C or °F) selection
Press UNIT button to toggle the temperature unit

MAINTENANCE
Cleaning and storage:
1). The meter should be cleaned with a damp cloth and mild
detergent when necessary.
2). Store the meter in an area with moderate temperature
and humidity.

DISABLE ABC FUNCTION
The meter is default with ABC for automatically
It assumes that the area being tested receives fresh air with
a CO2level of approximately 400ppm at some period of time
during the seven days. It is not suitable to use desktop CO2
in closed areas with consistently high CO2levels 24 hours a
day.
For example, if the monitor is located in 24 hours area, such
as hospital or convenient stores, the ABC function should
be turned off for not being calibrated with high CO2level.
When adaptor plug in, long press POWER button to turn off
the meter. Hold MODE+UNIT and press POWER button.
Display shows “AbcOn”. Press SEL/R to select ABC
function ON or OFF. Press TRH/M to save setting and meter
will restart automatically.
Step2:Hold MODE+UNIT
Step1:Long press POWER turn off meter
Step3:Press POWER to enter ABC function.
