1. Part Names and Functions
1.1 General Outline
This instrument (Model 3718-A/3719-A ）is a light-scattering laser particle sensor
using a laser diode as the light source. The output of the measurement data is from
4-20mA, based on the current system.
This instrument is connectable to the “Clean Room Monitoring System （CRMS ）”,
allowing it to perform measurements in a clean room environment for a prolonged
time.
The status lamp allows this instrument to display LD errors and flow rate errors.
When a particle concentration higher than the configured one in the alarm setting, is
detected the device will output the alarm signal.

Before starting a measurement, the parameter settings must be configured.
Prior to the parameter settings, please read the software operation manual.
Before setting the parameters, connect the 3718-A/3719-A, a power supply for
3718-A/3719-A, the USB-RS485 Converter (converter, connecting cable) and a PC
（that has the software installed）.
Sampling time settings: The settable range is 1-60 seconds, at a rate of 1.0 second.
All data compiled within the configured sampling time will be
transmitted via the analog output (4-20mA).
This sampling time is shared between 2 channels.
* The factory setting is 1 second.
Output range settings: Configure the range of the particle count and concentration.
The analog output will be 4 to 20mA within the configured
range. The following figure shows this setting range, which is
settable for each channel.
* The factory setting is 01 (0-10CNT).
