Startup
Clean the exterior surfaces
N O T I C E
Never spray the instrument directly with liquid or a vaporous hydrogen peroxide
(VHP) stream. When liquid solutions get into the counter flow path or electronics,
sensor damage occurs.
N O T I C E
Do not allow disinfecting chemical vapor to get into the instrument enclosure and
come in contact with the instrument electronics.
Wipe the exterior surfaces with a lint-free tissue made moist with
isopropyl alcohol (IPA). The sample (isokinetic) probe can be autoclaved
for cleaning.
Clean the interior surfaces
Use the supplied 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
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
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
instrument on page 13.

Purge the
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 the supplied 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.
