2 INTRODUCTION
2.1 General Description
Thank you for purchasing our YESDUST Particulate Sensor.
TheYESDUST is a general purpose particulate sensor for use with aYES multi-channel monitor
(e.g.YESAIR, YESAIR-D andYES Plus LGA). It operates from an internal rechargeable nickel
hydride battery pack and connects to the auxiliary port of the YES multi-channel monitor with
the supplied interface cable.The measured readings are displayed as another sensor on the LCD
display of theYES multi-channel monitor, and are also data logged to the YES multi-channel
monitor internal ash card, if utilized.
YESDUST counts particulates between 1 and 10 microns in size. It has been designed for use
as a general purpose indication of a particulate problem and should not be considered for
applications requiring high accuracy such as“clean rooms”.
2.2 Key Features
• Low cost
• Light weight
• Quick response
• Long life
• Real time display on aYES multi-channel monitor (e.g.YESAIR & YES Plus LGA)
• Data logs to SD ash card in a YES multi-channel monitor

WARNING: USE RECHARGEABLE NICKEL HYDRIDE BATTERIES ONLY. USING NON-
RECHARGABLE BATTERIES MAY RESULT IN DAMAGE TO THE UNIT.
Step 4:
Replace the front cover and secure it with the screws.
Connecting to a YES Multi-Channel Monitor
NOTE: Ensure that theYES multi-channel monitor is powered o before connecting the
YESDUST.
Step 1:
Connect the included communications cable to the DATA OUT port on the YESDUST
Step 2:
Connect the other end of the cable to the AUX port on the YES multi-channel monitor.
Step 3:
Set the switch on the YESDUST to the ON position. The COMM light will turn on red to indicate
that there is power but the YESDUST has not established communications with theYES multi-
channel monitor.
Step 4:
Power up the YES multi-channel monitor.
Step 5:
Once communications have been established, the COMM light will turn green, and occasionally
ash amber during communication.
Monitoring
Step 1:
Connect the YESDUST to the YES multi-channel monitor.

Step 3:
The CHARGE light will turn amber while the batteries are charging. Once complete, the CHARGE
light will turn green.
Disconnecting
To disconnect theYESDUST from theYES multi-channel Monitor, unplug the communication
cable.TheYES multi-channel monitor will display“Aux port has been removed”and the COMM
light on theYESDUST will turn RED after approximately 45 seconds.

7 MAINTENANCE
TheYESDUST requires virtually no maintenance; however CETCI recommends a service check of
the YESDUST once per year to ensure that the sensor is in proper working order.
8 TROUBLE SHOOTING
YESDUST won’t power up with batteries:
1. Check that the batteries are installed and that the polarities are correct
2. Ensure that the batteries are charged.
3. If the batteries do not hold a charge, replace them with 4 new rechargeable AA nickel metal
hydride batteries.
YESDUST won’t communicate with YES Multi-channel Monitor:
1. Check that the interface cable is undamaged
2. Check that the interface cable is connected to the DATA OUT port on the YESDUST and the
AUX port on the YES Multi-channel Monitor.
3. Turn the YESDUST o, wait 30 seconds, and turn it back on.
4. Turn the YES Multi-channel Monitor o, wait 30 seconds, and turn it back on.
YESDUST won’t power up with wall adapter, or will not go into charge mode:
1. Unplug the wall adapter from the YESDUST and the wall.
2. Check the cord, wall plug, and jack for damage.
3. Reconnect the power jack to the YESDUST and plug in the wall adapter.
If these troubleshooting steps do not resolve the issue, or if an issue not covered above arises,
please contact the CETCI service department, at [email protected] or +1.604.940.8741, for
