operating the instrument. Do not step on or place heavy objects on the cord.
Using a damaged power cord could result in a fire or electric shock.
This product is not explosion proof, so do not use it near combustible or
flammable materials.
Do not use a damaged AC adapter cord or loose power outlet. Doing so could
result in a fire, electric shock, or other hazards.
Do not connect the AC adapter into an outlet with multiple items sharing the same
extension cord or plug adapter. Doing so could result in a fire or electric shock.
Do not touch the AC adapter cord or outlet with wet hands. Doing so could result
in an electric shock.
Do not attempt to disassemble or modify the product. Doing so could result in an
accident or fire.
Do not permit water, other liquids, or gases to enter the product. Doing so could
result in a fire or malfunction.
If a problem occurs during operation, immediately stop operating the product, and
remove the cause.
If it is determined that the product caused the problem, turn OFF the power
switch, disconnect the AC adapter from the power outlet, and then contact your
Sibata representative. Never operate the product if it is not functioning normally.
Also, never allow anyone other than a qualified service engineer to disassemble
or modify the product. Doing so could result in an accident or malfunction.
Unplug the AC adapter from the power outlet and remove the battery from the
battery case before cleaning or inspecting the product.
When not in use, unplug the AC adapter from the power outlet and remove the
battery from the battery case before storing the product.
It is dangerous to look directly at the beam of the laser in the laser diode used in
this product. Accordingly, never disassemble or modify the interior of the
detector. Also, never check the laser light inside the detector with the air
sampling port removed and the power switch turned ON.
Never block the exhaust port.

This product is intended for measuring dust levels. Do not use it for any other
purpose not indicated in this manual. Doing so could result in malfunction.
The normal operating temperature range of this product is 0 to 40 °C, with
humidity between 5 and 90 % RH (and no condensation). Operating the product
outside these temperature and humidity ranges could reduce performance,
shorten the service life, or cause malfunction.
Never attempt to connect to the connector using wire or other metal objects, or
any other method not specified in this manual. Doing so could result in
malfunction.
Do not subject the product to strong impacts or drops. Doing so could result in an
accident or malfunction.
Do not lift or carry the product by holding the air sampling port. Doing so could
damage the product.
Level the product and secure it to prevent tipping over. Not doing so could result
in an accident or malfunction.
Do not operate or store the product near a fire. Doing so could result in an
accident or malfunction.
Keep the product away from sources of noise. Do not operate the product in
locations with a strong magnetic field.
Do not apply water directly to this product. Doing so could result in malfunction.
Do not insert screws or other foreign objects into the air sampling port. Doing so
could cause a malfunction. If any foreign object gets inside the air sampling port,
turn OFF the power switch, disconnect the power cord from the power outlet, and
then contact your Sibata representative.
Please be aware that in the unlikely event of a product failure, Sibata bears no
responsibility to compensate for data not acquired or recorded, and is not
responsible for loss of data or for other direct or indirect damages incurred from
such loss. Be sure to back up data on a regular basis in case of an accident or
failure.

It is small and lightweight, which simplifies transport and measurement
layout procedures.
Since a color graphics LCD has been adopted for the display, visibility is
excellent.
When the LCD screen is OFF, the operational status can be checked from
a distance via the LED indicator.
The trend graph display is convenient for visualizing temporal fluctuations
in dust concentration.
It is not necessary to move to a different screen to record the measurement
data.
Filter replacement is easy and maintenance is simple.
If you pre-configure the units as mg/m3or μg/m3, values converted to mass
concentration can be displayed. (You must calculate the K factor and then
set it in this product.)
The mass concentration conversion will be reflected only in the measured
values in the LCD screen. It will not be reflected in the output or log data.
1 About This Product
1-1 Overview
This product is a dust indicator that makes use of scattered laser light.
When airborne dust in a darkened room is irradiated with light, if the physical
properties of the dust are kept under the same conditions, the amount of light
scattered by the dust is proportional to the mass concentration. Using this
principle, the concentration of airborne dust can be measured as a relative
concentration.
The relative concentration obtained with the dust indicator must be converted to
the mass concentration.
Accordingly, a mass concentration conversion factor is determined based on
consideration of various factors including the particle size, distribution, specific
gravity, form, and optical properties.
In comparison to the filtration collection method, a relative concentration indicator
has the advantage of obtaining a large amount of data in a short time. If the
temporal and spatial fluctuations of airborne dust are being tracked, they can be
evaluated just from the relative concentration, so the relative concentration
indicator can be used to simplify the measurement process in this case.

indicator.
At this point, the battery level indicator changes to the full icon (green) on the
left side of the figure above.
4 Power Supplies
The instrument can be used with batteries (rechargeable batteries of the same type
are also acceptable), or an AC adapter.
4-1 Batteries
(1) Remove the battery case cover.
Turn the battery case cover in the
direction of the arrow in the figure
and then pull it forward.

19
(2) Insert six AA batteries into the
battery case. (Alkaline batteries are
recommended.)
With alkaline batteries, the instrument
can be used continuously for
approximately 10 hours*.
* When the LCD is turned OFF by the
sleep function.
The factory default turns OFF the
LCD 90 seconds after the last switch
operation.
→See 8-5-1 LCD Screen Sleep Function.
(3) Reverse the procedures to reattach
the battery case cover.
To complete the attachment, as
shown in the figure, align the
mark on the cover with the mark
on the main unit and turn the cover
clockwise until the mark aligns
with the mark on the main unit.
4-2 Backup Battery
There is a backup battery case above the
main battery case.
