Alarm setting: Can be set within the range of 0-100% of the measurement range in 1% steps.
Alarm settings can be set for each channel.
An alarm is output when the number of particles detected exceeds the
concentration alarm value.
The following is a list of the most important
For details on alarm settings, refer to "2.4 Analog Output Terminal
Connection".
Please do so.
The factory default setting is 100 (each channel).
Address setting: Sets the address of the device. The setting range is 1-247. Used for
identification when multiple units are connected and used.
The following is a brief summary of the results of the study. The factory default
setting is 1.
Sensor communication settings: Configures communication settings for the monitoring
system.
Configure the communication settings between this unit and the
host PC.
Baud rate: select from 9600, 19200, 38400 bps Data
bit: 8 bit
Parity: Select even, odd, or none Stop bit:
Select 1 bit or 2 bits
The factory default settings are 9600 bps, 8 bit, none, and 2 bit.
Error output setting: When flow rate or LD error is detected, current output is
performed or not performed.
ON: The current output is changed according to
the contents of the abnormality. OFF:
Measured value is output even if an
abnormality is detected.
*Please set according to the system to be connected.

Check condition of vacuum source
The status of the vacuum source can be checked by the STATUS lamp on the main unit or
by the output current from analog output pins 9-12. 1-1.8 mA or 3-3.8 mA output
current outside the range of pin 9-12 indicates a normal condition.
However, this output is enabled when the error output setting in
2.2 Parameter Setting is ON.

before insertion.
The analog terminal connector is removable, but should be kept in place as much as
possible to prevent loss.
