2.1 Installing Batteries
4. Insert batteries ensuring the battery polarity is correct. This instrument
requires six (6) AA size batteries. Types of batteries that can be used
are: Manganese (R6), Alkaline (LR6) or Ni-Cd batteries.
The six (6) batteries must be of the same type. Do NOT mix different
types of batteries. Mixing different types of batteries or incorrect
battery polarity may cause battery leakage or damage to the instrument.
* Batteries CANNOT be recharged by the (optional) AC adapter.
3. Lift the cover away from the instrument.
1. Press down the battery cover with your
finger as shown left.
2. Slide the cover toward the bottom of the instrument.
5. Put the cover back on by reversing the above procedure.
Types of batteries that can be used
-Manganese (R6), AA batteries
-Alkaline (LR6), AA batteries
-Ni-Cd, AA batteries

2.2 Connecting Probe
CAUTION
* Make sure that the power is OFF when connecting
or disconnecting the probe.
1. Put the probe’s connector on the main body’s probe socket.
2. Push the connector in until you hear a click.
CAUTION
* DO NOT squeeze the probe into the main body or twist the
probe when it is attached, as it may cause a serious damage
to the instrument.
2.3 Disconnecting Probe
CAUTION
* Make sure that the power is OFF when connecting or
disconnecting the probe.
1. Pull up the probe’s connector (See chart 1-A).
2. Pull out the connector from the main body with the connector up
(See below chart 2).
CAUTION
* DO NOT twist the probe when it is connected,
as it may cause a serious damage to the
instrument.

2.4 Turning ON/OFF the Power
The power switch for turning ON/OFF the instrument is located at the side of the instrument. When powered up after
a probe is connected, the KANOMAX logo, its model name and software version will be displayed for a few seconds
before the measurement mode screen shows up.
Battery Level Indicator
The below shows how the indicator changes as the batteries are running low:
The above warning will be displayed when a probe is not
properly connected or not connected at all. If this warning
shows up, turn off the instrument and check if a probe is
connected properly.
Power Switch
I: Power ON
Ｏ: Power OFF
Check the “Battery Level Indicator” in the upper right corner to
confirm the remaining battery level. When the battery level drops
to a level requiring replacement, the indicator starts blinking.
Since each battery has different battery life, it is recommended to
replace them ahead.

2.5 Precautions for Measurement
2.5.1 CO and CO2Measurement Precautions
Air diffusion condition (flow condition) affects the response time of CO and CO2sensor. In order to obtain an
accurate measurement result, perform a measurement in the place which has the flow of air as much as possible.
Mechanism of CO and CO2sensor has a limitation in accuracy when a measurement takes place under drastic
thermal change. When the sensor and the measuring object have apparent thermal discrepancy, leave the probe
in open air for at least 20 minutes before starting a measurement.
After turning the power ON, sensor circuit requires some time to stabilize a detecting circuit. For an accurate
measurement result, leave the instrument for about 5 minutes after turning the power ON.
Keep this sensor away from expiratory air; exhaled air contains more than 10,000ppm of CO2and exhaled air of
smokers contains several ppm of CO. In order to perform an accurate measurement it is recommended to use
the provided prove stand and to place the probe away from you while measuring.
<How to use the Probe Stand>
Lightly push the grip part of the probe into the probe stand’s holder as shown in the below figure 1.
* Make sure to place the probe stand on a stable flat surface. Placing the probe on an unstable surface may cause the
probe stand to fall and damage the probe.
<Precaution for Storing the Main Unit and Probe>
* Our CO detection sensor inside the probe uses an electrochemical sensor. As this sensor uses electrochemical
reaction, it reacts to not only CO but also the similar types of gas. If the sensor is used or stored in an environment
containing organic solvents, paint, medical agents, oil or corrosive gas, the CO sensor will show an abnormal
reaction causing zero-point drift, sensitivity variations or damage to the sensor.
◆Typical Reactive Gas
Hydrogen Sulfide, Sulphur Dioxide, Nitric Oxide, Nitrogen Dioxide, Chlorine, Hydrogen and Ethanol
CAUTION
* DO NOT use or store the instrument in the environment containing organic solvents, paint, medical
agents, oil or corrosive gas.

<Atmospheric Pressure Correction>
When atmospheric pressure at a measuring site is abnormal (such as at high altitude), follow steps below to set
atmospheric pressure (default setting: 1013hPa).
Since the change of weather does not significantly affect the atmospheric pressure as long as the measuring site
is same (excluding the case of typhoon), once you set atmospheric pressure, you do not need to set it every time.
Display
Procedure
Press key to bring up the MENU screen.
Use key to select “7.CALIBRATION”, and press key.
Use key to select “4. ATMOS. PRESS SET”, and press key.
Use key to set atmospheric pressure value, and press key.
Use key to select “5. SAVE INFO”, and press key to go
back to the MENU screen and the setting is completed.
2.5.2 Temperature Measurement Precautions
The response time for temperature measurement improves as the air flow increases. Wait for the reading to
become stable before taking the data.
When a measurement is performed in a no-airflow condition, the air temperature reading may become higher
than the actual due to the heat generated by the lamp. It is recommended that the measurement is performed in
an environment with at least 0.1m/s airflow to obtain accurate readings.
2.5.3 Humidity Measurement Precautions
If a measurement is performed in the place where the humidity is high for a long period of time or temperature
changes rapidly, humidity reading may become exceedingly high due to dew condensation. When dew
condensation is built up, leave the probe in the atmosphere of less than 40%RH for 24 hours to dry it out.
-- Comparison with Assman Aspiration Psychrometer --
The quality and accuracy of IAQ Monitor’s humidity measurement function is ensured by strict calibration with
traceability in Japanese National Standards of JEMIC (Japan Electric Meters Inspection Corporation). This
instrument provides stable measurement as an electronic hygrometer, so it can be used as Assman Aspiration
Psychrometer. Assman Psychrometer sometimes reads higher humidity comparing to the IAQ Monitor since
handling methods such as how to wrap the wet bulb by gauze or how to handle the dirt affect Assman
Psychrometer. Assman Psychrometer shall be handled with care. For more details on handling Assman
Psychrometer, refer to the Japanese Industrial Standard (JIS) Z 8806 Humidity - Measurement Method.

5. Measuring Percent Outdoor Air (%OA MODE)
%OA MODE is a measurement mode to calculate Percent Outdoor Air either with temperature or CO2.
The calculation is based on below formula:
%OA＝(R_A –S_A) / (R_A –O_A) × 100
* %OA：Percent Outdoor Air
R_A：Temperature or CO2concentration of Return Air
S_A：Temperature or CO2concentration of Supply Air
O_A：Temperature or CO2concentration of Outdoor Air
A measurement takes place in the following sequence;
Return Air -> Supply Air -> Outdoor Air
Average value in each point is used to calculate percent outdoor air.
Temperature or CO2concentration data at each point (TRIAL(1) ~ TRIAL(N)) will be also stored in the memory.
TRIAL (1) (2) (3)……(N) TRIAL (1) (2) (3) ……(N) TRIAL (1) (2) (3) …… (N)
