cord or plug adapter. Doing so could result in a fire or electric shock.
•Do not touch the power cord or outlet with wet hands. Doing so could result in an electric shock.
•If using an extension cord to use the product outdoors, make sure it is a waterproof model.
Sibata is not responsible for any accidents involving an extension cord.
•Always ground the unit. During the grounding process, disconnect the power cord from the
outlet. Not doing so could result in a fire or electric shock. Never ground it to a gas pipe. Doing
so could result in an explosion or fire.
•Never attempt to disassemble or modify the product. Doing so could result in an accident or
malfunction.
•Do not permit water, other liquids, or gases other than atmospheric air 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 identify and
eliminate the cause. If it is determined that the product caused the problem, switch OFF the
power switch, disconnect the power cord from the power outlet, and then contact your Sibata
representative. Never operate the product if it is not functioning normally or have it repaired by
anyone other than an authorized service engineer. Doing so could result in an accident or
malfunction.
•Always grip the plug to unplug the power cord. Pulling on the cord could damage the cord and
result in an electric shock or fire.
•Always disconnect the power cord from the outlet before cleaning or inspecting the product. Not
doing so could result in an electric shock or short circuit.
•Unplug the power cord from the outlet when the product is not in use. Not doing so could result
in a fire or malfunction.

CAUTION
•This product is intended for measuring dust levels. Do not use it for any purposes other than
indicated in this manual. Doing so could result in malfunction.
•The product is designed for use with a 100 V AC power supply. Do not use it with power supply
voltages other than those specified. Doing so could result in malfunction.
•The normal operating temperature range of this product is 0 to 40 °C, with humidity between 10
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 drop or otherwise subject the product to large impacts. Doing so could result in an
accident or malfunction.
•Do not lift or carry the product by holding the air sampling tube. 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. Doing so could result in malfunction.
•Exposing the product to strong sunlight could cause the main unit to become very hot. Be
careful to avoid burn injuries from touching such hot surfaces.
•Do not expose the product directly to water, such as by spraying it with a hose. Doing so could
result in malfunction.
•Be sure to operate the pump with a protective filter installed. Sampling air for long periods
without a filter installed could result in malfunction.
•Do not insert screws or other foreign objects into the air sampling port. Doing so could result in
malfunction. If any foreign object gets inside the air sampling port, switch 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

3 About This Product
3-1 Overview
This dust monitor consists of a cabinet containing a light-scattering type dust indicator that is able
to continuously measure dust levels in outdoor environments. Using the product makes it possible
to conveniently measure the outdoor dust concentrations.Also, thanks to an extensive selection of
output functions, multiple units can be used to monitor dust concentrations at construction sites or
along the boundaries of undeveloped building sites.
Main Features
•Installing a filter allows a single FLD-1 dust monitor to be used for concurrent measurements
to determine the mass concentration conversion factor.
•The compact design allows easy portability and placement.
•Extensive output functions allow various system configurations.
•A logging function allows uploading measurement results to a computer.
•Maintenance simply involves replacing the filter cartridges and the filters.
•The internal heater minimizes any increase in measurement values due to condensation or
other factors.
•PM2.5 particles can be measured by installing an optional PM2.5 cyclone particle size
selector.
•Connecting an optional weather sensor makes it possible to simultaneously measure the
external air temperature, relative humidity, wind direction, and wind speed as well as dust.

4 Preparation
4-1 Installation
WARNING
When installing the instrument, be sure to secure it to
a sturdy building or structural member.
If used unsecured, strong winds or shaking from an earthquake
or construction could cause the instrument to tip over or fall,
resulting in accident, injury, damage, or malfunction.
WARNING
Be sure to confirm the load-bearing capacity of the
location where the instrument is to be placed.
The instrument weighs about 14 kg (15 kg including optional
parts).
Be sure to confirm that the site is strong enough to bear the weight
of the instrument before installation.
Installing the instrument without confirming the load-bearing
capacity could result in accident, injury, damage, or malfunction.
CAUTION
When transporting the instrument, be sure to lift on the
main FLD-1 unit.
Lifting it by holding the air sampling tube or optional weather
sensor could result in damage or malfunction.
The instrument can be mounted by fastening it to a single pipe or fastening it to a stand or table
that is anchored to the ground with anchor bolts, for example. Secure the instrument using the
means appropriate for the circumstances at the given installation site.
4-1-1 Fastening the Instrument to a Single Pipe (Optional)
The instrument can be mounted to a single pipe
(with a 48.6 mm outer diameter) by using the
optional support column mounting brackets.

Set of 2 (080040-633)

20
Attaching the Support Column Mounting Brackets
(1) Remove the four bolts from the back of the
instrument.
Note:Bolt head size is 12 mm (width across
flats).
(2) Align the bolt holes on the instrument with
holes in the support column mounting
brackets and then fasten the instrument
using the bolts removed from the
instrument.
Note:Orient the support column mounting
brackets in a direction that makes it
easier to mount the instrument.
(3) With the clamp on the support column
mounting brackets open, place the bracket
against the pipe, close the clamp, and
fasten the nut.
Note:Nut size is 17 mm (width across flats).
(4) Lastly, confirm that the instrument is fastened securely.
WARNING Always attach two support column mounting brackets.
Installing only one bracket could cause the instrument to fall and
result in accident, injury, damage, or malfunction.
