Clean the interior surfaces
Use a
zero count filter to remove contaminants such as particles, lint or
dust from the interior surfaces of the instrument and the air inlet tubing.
When the count goes to zero, the interior surfaces and inlet air tubing
are clean.
Items to collect: zero count filter
1. Attach the zero count filter to the air inlet tube.
The zero count filter prevents any external particles from going in the
instrument.
2. Start sample collection and operate the instrument for at least
30 minutes. Refer to Manual operation on page 22.
3. Monitor the room air in 5-minute intervals and continue until the
particle count is 0–1.
Optional: To record the data, set the Sample Timing: Sample setting
to 5 minutes. Refer to Configure the instrument on page 17.
4. If the particle count does not go to 0–1 after nine or ten 5-minute
sample periods, purge the instrument overnight. Refer to Purge the
instrument on page 16.
Purge the instrument
Do a purge to get a particle count of 0–1. Typically, a purge is done
before a test to make sure that there is a baseline reference for the
instrument.
1. Remove approximately 2.5 cm (1 in.) of tubing from the sample
probe-end of the air inlet tube to remove any stretched or scored
section.
2. Attach a zero count filter to the air inlet tube.
3. Operate the instrument for 24 hours.
4. If a particle count of 0–1 is not shown after 24 hours, identify if the
source of the particles is the air inlet tubing.
a. Install the zero count filter directly on the air inlet fitting.
b. Operate the instrument for another 15 minutes.
c. Monitor the room air for 5 minutes and record the results. Do this
step up to four times until the particle count is 0–1 in a 5-minute
sample.
d. If a particle count of 0–1 is shown, the air inlet tubing is the
source of the particles. Replace the air inlet tubing.
e. If the particle count does not go to 0–1, contact technical support.
Operation
Configuration
For initial configuration, connect the
instrument to a PC.
After initial configuration, change the configuration settings as necessary
by direct connection to a PC or through a ModbusTCP connection. For
configuration through a network, only the LAN settings can be changed.
Refer to Configure the LAN settings through a network on page 19.
Connect to a PC
Items to collect:
• Setup utility CD
• Service port cable
• PC with Windows
®
2000 Professional, Windows XP Professional,
Windows Vista (32-bit), Windows 7 (32-bit or 64-bit in XP emulation
mode)
• USB to RS232 adapter if the PC does not have a RS232 port
1. Make sure that Microsoft .Net Framework is installed on the PC. If
not installed, open the dotnetfx.exe file on the setup utility CD and
install the application.
Note: The user must be logged on to the PC as an Administrator.
2. Copy and paste the SetupUtility.exe file from the setup utility CD to
the PC.
3. Connect the Service port cable to the Service port on the instrument
and a COM port on the PC.
