Warning
（Forbidden）Do not use the AC adapter other than the provided one with the
instrument.
Using an inappropriate adapter may damage the instrument.
It may generate heat and cause fire.
（Do not remodel/disassemble）Never disassemble, modify, or repair.
This instrument uses a Class 4 laser diode as the light source.
Exposure to the laser may cause loss of eyesight and other injury.
Never open the instrument other than the battery compartment.
（Handle properly）Handle the instrument properly in accordance with the

iii
instructions provided in this manual.
Failure to do so may cause electric shock, fire, or sensor damage.
（Caution）If abnormal noise, smell, or smoke is observed, or if liquid has
entered the instrument, turn off the power immediately, remove the batteries
or pull out the plug.
Failure to observe the above may cause electric shock, fire hazard, or
damage.
Please contact your local distributor or Kanomax service center for repair.
Caution
（Handle properly）Pull out the plug when the instrument is not in use.
Failure to do so may cause electric shock, fire hazard, and circuit damage.
Notice
（Forbidden）Do not use or keep the instrument in hot, humid, or dusty
environment. Do not expose the instrument to direct sunlight for a prolonged
period of time.
The instrument may not function properly out of the specified operational
temperature range.
（Forbidden）Do not subject the instrument to strong impact.
Dropping or hitting the instrument may cause damage and malfunction.
（Forbidden）Do not wipe the instrument with volatile solvent.
The body may deform or deteriorate. Use soft dry cloth to remove stains. If
stains persist, soak the cloth in neutral detergent and wipe the instrument
with the cloth.
（Forbidden）Do not touch the LCD screen with a sharp-pointed object or
with excessive pressure.
It may cause distortion of the screen or a malfunction.
A rapid temperature change may cause a malfunction of the screen.
（Handle properly）When storing the instrument, put the instrument in the
carrying bag and keep it in a place with an ambient temperature of -10 to
50℃ and no condensation.
（Forbidden）Do not dispose of the instrument as household waste.
Please note that the disposal of the instrument and batteries should be in line
with your local or national legislations. For details, please consult with your
local distributor.

Preparation Before Measurement
AC adapter
Be sure to use the provided AC adapter when using the Main unit.
Warm-up
If the device is brought in from a different temperature place, prior to a measurement, let
the device allow adapt the current temperature environment. Be sure to warm up the
device at least for 10 minutes before starting a measuring. A sudden temperature change
may cause a measurement error.
Measurement Procedures
Internal Cleaning
Prior to use, purge the device (Interior cleaning) with the Zero Filter.
Remove the Inlet Protective Cap, and attach the Zero Filter to the inlet.
Turn the power on and press the Start button to perform a continuous measurement for
10 to 15 minutes. When the measuring count value is stable and confirm the value is
retained at least for 10 seconds, finish a measurement.
(If the value doesnʼt reach to zero, block the inlet of the Zero Filter for a few seconds to
accelerate the cleaning while measuring.)
Remove the Zero Filter from the inlet.
Measurement
Connect the Tygon Tube to the inlet. (Using the Tube leads to less influence by the
ambient environment.)
Set the required setup on the General setup and Measurement setup sub-menus.
Set the measurement conditions in the Measurement mode, and select the measurement
conditions in the Preset.
Return to the Main screen. Press the Start button to perform a measurement.
The measurement will complete automatically or by pressing the Stop button.
The previous measurement results can be viewed from the History sub-menu.
Do not run the device for eight (8) hours or more per day.
Try to avoid a suction sampling in the general atmosphere. A suction sampling in the
general atmosphere may cause contamination in the optical system, resulting in providing
unstable measurement.

7
Errors
The following errors can occur by the self-diagnostic function. Even if an error occurs, the
measurement and other processes will be continued.
Laser power failure The laser diode may be defective or reached the end of its life.
Flow rate
The pump current is increasing or decreasing. If the inlet
Protective Cap is attached, remove the Cap. If the error
persists, the pump may be defective or reached the end of its
life.
Maximum
measurable
concentration
is exceeded
The concentration exceeds the maximum measurable range.
Perform the measurement at a cleaner location or attach the
Zero Filter to the device to measure.
User Interface
Title Screen
Turn on the power to the device. After four (4) seconds, the Main screen will appear
automatically. Or tap the Title screen to go to the Main screen.
Main Screen
There are three main screens as required. You can go to the sub-menu screens from the
main screens.
