How
to
Use this Manual
·Where to Start
. . .
If
you have just received a new particle counter, read the following sections
of
this
manual.
If
the particle counter is ·already set
up
andworking; you·can

...
• Unpacking and Initial Inspection
• Initial Power Turn-on
Section
2,

...
• Counting Particles
• Using the Front-Panel
• Setting Programmed Functions
After reading these sections, you can use the rest
of
the manual
as
.a reference. Each
section
of
the manual has an introduction that tells you what you will find in that
section. The manual also has
an
AppendixA that contains supplemental information

if
problems occur with the particle counter. ·
Manual Conventions
This manual shows front-panel nomenclature in capital letters. For example, the
"enter" key will appear
as
ENTER in the manual. Some keys also contain labeled
lights. For example, the COUNT MODE key has two lights labeled "CUM" and
"DIFF". The names of these keys are followed by the names
of
the lights. For
example, COUNT MODE: CUM/DIFF.
Each section
of
this manual has its own series of page numbers that are prefixed with
the section number. For example, Section
1,
Getting Started, is numbered 1-1, 1-2,
1-3, etc. and Section

Electrostatic Discharge
Electrostatic discharge (ESD) can damage or destroy electronic components in those
counters using solid-state laser sensors (see "Specifications"
in
Section 1 for type
of
sensor in your counter). Therefore, all service or maintenance work should be done at
a static-safe work station. A static-safe work:station can
be
'c'reated by doing the
following:
• ;use a grounded conductive table mat and resistor-isolated wrist-strap combination
• 'Earth-ground all test instruments to prevent a buildup
of
static charge
··
WARNING
Using a wrist strap without an isolation resistor will increase the severity
of
an
electrical shock.
CAUTION
The laser driver board, mounted on the laser sensor
of
the particle counter, contains
wire leads from an extremely.static-sensitive laser diode.
Do
not touch the laser driver
board
or
any attached cables unless you are ESD protected.

Getting Started
Introducing the Particle Counter
The particle counter measures airborne particles in six size ranges
at
the same time, and
displays the number
of
particles in each range as a cumulative
or
differential count.
The
counter is a state-of-the-art laser-based microprocessor-controlled instrument.
It
provides adjustable count alarms, automatic calibration verification, and
computer-controlled operation through a serial port.
The counter's laser and optical lenses create a laser beam that is used to detect particles.
The
airborne particles pass through the laser beam, deflecting bursts
of
light onto a
solid-state photo diode that converts the light to
an
electrical pulse. The size
of
the
pulse is proportional to particle size. The microprocessor and its associated circuitry
sorts
and
counts these.pulses.
Accessories
RH/Temp and
Air
Velocity Probes
High
Pressure.
Diffuser
Instrument Cart
Carrying Case
Options
Plug into the counter rear panel. The RH/femp probe monitors
relative humidity.(lO to
90%)
and.temperature.(specify,Q to··.
100°F,
or
-IS· to 38°C): The·
air;
velocity··'probe monitors air ·
velocity·(specify·so to 120 feet/minute,
or410
to 616
mm/second). The particle counter displays the reading
of
either
probe.
Allows the particle counter to measure in pressurized systems
(30-150 psi). Connects in series with particle counter inlet.
Allows easy movement
of
counter between sampleJocations.
Protects the counter during shipment or storage.
The
following option can be installed when you order your counter
or
any time
thereafter
if
you return your counter to the factory.
External Printer

Provides same printouts
as
built-in printer, but at distances
removed from counting area. Replaces built-in printer.
