The battery can be recharged while the instrument is
turned OFF or ON. The bar indicator shown on the right
displays the charging status while the battery is being
charged.
When the battery is fully charged as shown on the right,
unplug the adapter, and charging is complete.
Caution:
1) The input of the AC/DC adapter is AC 100-240v and the output is DC 12.5v. Do not use an
adapter other than the one supplied with the instrument. Use of unspecified adapters may
cause charging failure or damage to the instrument.
2) The estimated continuous operating time using the rechargeable Ni-MH battery is approx. 4.5
hours. Charging time is approx. 5-8 hours.
3) If the instrument is not to be used for an extended period, the battery should be charged once a
month in order to extend the service life of the battery.
4) Before starting a measurement, if the adapter plug is inserted into the socket while the

4.3 Confirming the Sensor Condition
When the instrument is powered on, the screen below will display with a flashing “WAIT”
message in the operating status field. After approx. 10 seconds the sensor will stabilize and the
“WAIT” message will stop flashing.
The measurable range of the sensor can be confirmed by the bar indicator and the frequency
displayed on the screen.
1) Confirming the Measurable Range using the Bar Indicator:
The bar indicator will be at full length immediately after cleaning. The bar will move to the
right, decreasing in length as dust accumulates on the sensor. When the remaining length of
the bar indicator is short, or when “CLEANING” is flashing, the sensor should be cleaned
immediately. (Refer to section 4.4 and 4.5 for cleaning.)
2) Confirming the Measurable Range using the Frequency display:
The frequency can be displayed by pressing the key, and hidden by pressing the
key again.
The frequency will increase as dust accumulates on the sensor. When the frequency exceeds
the Fundamental Frequency + 2000Hz, “CLEANING” will flash. Cleaning should be done
immediately.
* The frequency increases as the length of the measurable range bar indicator decreases.

Caution:
Confirm that the bar indicator has sufficient length before starting a measurement. Never leave
dust accumulated on the sensor as it may prevent the bar indicator from recovering even after
providing cleaning. It can also affect the frequency display, which will affect the measurement
accuracy.

4.4 Cleaning the Sponge
Preparation Before Cleaning
1) The sponge on the cleaning device must be moistened
before use. If the sponge is unclean or stained, put the
cleaning device into a vessel filled with clean water with a
few drops of neutral detergent, and leave it for a few
minutes (this is not necessary for a new product).
2) When the stain is removed, wash the sponge with running
water and completely remove all detergent.
3) Use a folded tissue or paper towel on the cleaning device to
remove all excess water from the sponge. This process
should be repeated several times to ensure removal of all
moisture.
4) Put 1-2 drops of detergent (blue) on the SMALLER sponge.
5) Put 2-3 drops of purified water on the LARGER sponge.
Caution:
1) Note that the two sponges differ in size. The proper amount
of detergent must be dropped on the smaller sponge.
2) If the sponge is dirty or stained with oil that cannot be
removed by washing in clean water, put the cleaning device
into a vessel filled with clean water with 3-4 drops of
neutral detergent. After the stain is removed, wash the
sponge with clean water.
3) If the stain cannot be removed from the sponge or if the
sponge is damaged, the sponge must be discarded. Please
contact your local distributor or our service center to
purchase a new sponge.
4) Any water remaining on the cleaning device other than the
sponge itself must be removed completely using a folded
tissue or paper towel. If the cleaning device is inserted in
the instrument with water drops, they may attach to the
sensor or needle, causing recovery failure of the measurable
range or failure when applying high voltage.
5) Use of a sponge with excessive moisture may require a very
long time to dry. In addition, the instrument reading may
become unstable, and the “WAIT” message may not
display.
6) Do not use a detergent other than the one specified. Use of
other detergents may result in an oily film to remain or
accumulation of sediment, which will affect the
measurement.
8

4.5 Cleaning the Sensor
First, confirm that the high voltage is turned OFF. Then align the front end of the cleaning device
with the cleaning port, and slowly insert the cleaning device with the sponge side facing down.
The cleaning device must be inserted up to the scale line indicated on the back side of the cleaning
device. When the scale line reaches the port, stop inserting and wait for approx. 20 seconds. Then,
insert the cleaning device further, and pull it out from the other side. The sensor will then be dried,
and a flashing “WAIT” message will be displayed on the screen. Approximately 3 minutes is
required for drying. When the sensor is dried, the “WAIT” message will stop flashing. The bar
indicator of the measurable range must return to the initial position. If the indicator is not returned
to its initial position, the above cleaning process must be repeated again as there may be dust
remaining on the senor.
Scale line Cleaning device
Caution:
1) Ensure that the high voltage is turned OFF before cleaning the sensor.
Residual high voltage is not fully discharged right after power off. Before starting cleaning,
confirm that the pointer of the high voltage indicator is returned to the left end.
2) While the sensor is cleaned, the flashing “WAIT” message will be displayed. During this
period, high voltage cannot be supplied even if the [MEAS] key is pressed. This is not a
malfunction. When the sensor is dried, the “WAIT” message will stop flashing. Excess
moisture on the cleaning device could lead to a prolonged drying time. If that is the case, the
moisture on the sponge should be absorbed using a folded tissue or paper towel and cleaning
must be performed again.
3) Do not force the cleaning device in if the sponge is torn or protruding from the cleaning
device. Forcing in the cleaning device could apply excessive pressure to the sensor causing
damage.
4) Use of an unclean sponge could prevent the measurable range indicator from returning to its
initial position. Ensure that the sponge is completely cleaned before performing a sensor
cleaning.
5) Do not perform a sensor cleaning if the ambient temperature is below freezing.

4.6 Adjusting the Impactor Position
Impactor may be set in three positions. A stopper is provided for fixing the impactor in three
angles: 0°, 45°and 90°. Fix the impactor at the desired angle.
Rotation angle: 45° Rotation angle: 90°
4.7 Sampling Time
For how to set the sampling time, see Section 6. Setting the Menu”.
The initial setting of the sampling mode is 120s.
Change the setting according to the dust concentration of the environment to be measured.
When performing measurements in a high concentration environment, such as a work
environment, select 24s. For indoor measurement in a low concentration environment, select 120s.
For measurements in a high concentration environment, the cleaning frequency can be reduced by
setting a short sampling time. For measurements in a low concentration environment, the
measurement accuracy can be increased by extending the sampling time.

5. Measurement Method
5.1 High Voltage Supply
On turning on the instrument, the flashing “WAIT” message will be displayed. After a brief delay,
the “WAIT” message will stop flashing, and high voltage can be supplied. Press the [MEAS/CLN]
key to supply high voltage. The pointer at the left end of the high-voltage indicator frame will
move toward the right. The pointer will stop at the center of the frame under the black block.
When the sensor becomes stable, the operating status will change from “WAIT” to “READY” and
the instrument will be ready for measurement.

Caution:
1) When [START] key is pressed during a measurement, the measurement will stop and the
concentration reading will change to “- -.- -”.
2) When [MEAS/CLN] key is pressed during a measurement, the measurement will stop. The
high voltage supply will stop and the concentration reading will change to “- -.- -”. This
procedure allows emergency stop during a measurement or canceling a measurement.
3) If the dust sampled during a measurement exceeds the measurable range, the measurable
range indicator will change to a flashing “CLEANING” message. If a sampling time of 24s or
120s was selected, the measurement will continue. After the measurement is complete,
high-voltage supply will stop automatically to prevent further measurement. Perform a sensor
cleaning to restore the instrument to a measurable condition. When an arbitrary sampling time
was set using TSET, the measurement will stop immediately if the measurable range is
exceeded. The data sampled up to that point will not be saved in this case.
4) After the completion of each measurement, “STORE” will flash. This is asking whether you
want to save the data or not. You can ignore this message if you do not want to save the data.
5) The reading of 0.00mg/m³ will be flashing for 5 seconds after starting a measurement. This is
because the reading is updated every 5 seconds.
12

5.3 Measurement End
When the measurement is complete, the concentration reading will stop flashing. The displayed
value is the measurement result for the specified sampling time. The operating status display will
change from the elapsed time indicator to the “READY” message, and the number of data records
will change to a flashing “STORE” message. If you want to save the measurement result, press the
[MEMORY] key. Ignore the message if you do not want to save the result.
To start another measurement, press the [START] key.
To end the measurement, press the [MEAS/CLN] key to stop the high voltage supply. Then, turn
off the power.
“STORE” blinks
