Section 2 General Information
2.1 Safety information
Read this entire manual before unpacking, setting up or operating this equipment. Pay
attention to all danger and caution statements. Failure to do so could result in serious
injury to the operator or damage to the equipment.
To make sure that the protection provided by this equipment is not impaired, do not use
or install this equipment in any manner other than that specified in this manual.
2.1.1 Use of hazard information
DANGER
Indicates a potentially or imminently hazardous situation which, if not avoided, will
result in death or serious injury.
WARNING
Indicates a potentially or imminently hazardous situation which, if not avoided,
could result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation that can result in minor or
moderate injury.
Important Note: Indicates a situation which, if not avoided, can cause damage to the
instrument. Information that requires special emphasis.
Note: Information that supplements points in the main text.
2.1.2 Precautionary labels
Read all labels and tags attached to the instrument. Personal injury or damage to the
instrument could occur if not observed. A symbol, if noted on the instrument, will be
included with a danger or caution statement in the manual.
This symbol, if noted on the instrument, references the instruction manual for operation and/or safety information.
Electrical equipment marked with this symbol cannot be disposed of in European public disposal systems after
12 August of 2005. In conformity with European local and national regulations (EU Directive 2002/96/EC),
European electrical equipment users must now return old or end-of life equipment to the Producer for disposal at no
charge to the user.
Note: To return for recycling, contact the equipment producer or supplier for instructions on how to return end-of-life
equipment, producer-supplied electrical accessories and all auxiliary items for proper disposal.
This symbol, when noted on a product enclosure or barrier, indicates that a risk of electrical shock and/or
electrocution exists.
This symbol, if noted on the product, indicates the need for protective eye wear.
This symbol, when noted on the product, identifies the location of a fuse or current limiting device.
This symbol indicates a laser device is used in the equipment.
This symbol, when noted on the product, indicated the presence of devices sensitive to Electro-static Discharge
(ESD) and indicated that care must be taken to prevent damage with the equipment.

General Information
2.1.3 Electrostatic Discharge (ESD) considerations
Important Note: To minimize hazards and ESD risks, maintenance procedures not
requiring power to the analyzer should be performed with power removed.
Delicate internal electronic components can be damaged by static electricity, resulting in
degraded instrument performance or eventual failure.
The manufacturer recommends taking the following steps to prevent ESD damage to
the instrument:
•Before touching any instrument electronic components (such as printed circuit cards
and the components on them) discharge static electricity. This can be accomplished
by touching an earth-grounded metal surface such as the chassis of an instrument,
or a metal conduit or pipe.
•To reduce static build-up, avoid excessive movement. Transport static-sensitive
components in anti-static containers or packaging.
•To discharge static electricity from the body and keep it discharged, wear a wrist
strap connected by a wire to earth ground.
Handle all static-sensitive components in a static-safe area. If possible, use anti-static
floor pads and work bench pads.
2.1.4 Battery safety information
WARNING
An explosion can occur if the internal battery is replaced incorrectly.
Figure 1 shows the label that is displayed on the battery for the safety of the user.

General Information
2.2 General product information
The MET ONE Handheld Airborne Particle Counter–2 (HHPC–2) (refer to Figure 2) is a
portable instrument that measures, counts, stores and reports airborne particulates. The
standard MET ONE HHPC–2 holds 100 samples in the memory. The data records
include date, time, counts, sample labels, volume, alarm flags, temperature and relative
humidity. The user can download the data to a personal computer (PC) using the
included interface cable and software. The internal battery powers up the MET ONE
HHPC–2 when mobile or when connected to the AC power adapter.
Note: The AC power adapter provided with the unit is used for extended or stationary sampling.
The MET ONE HHPC–2 is used:
•To monitor the air quality in clean-rooms
•To monitor the air quality in manufacturing processes
•To monitor the air quality in pharmaceutical production
