PREFACE
The purpose of this manual is to provide complete operational, calibration and
maintenance details for the BGI PQ100 air sampler. This instrument has been
specifically designed to meet or exceed the operational requirements of a
Reference Method sampling device under 40 CFR Part 50, Appendix J
(AReference Method For The Determination of Particulate Matter as PM-10 in the
Atmosphere@) and was designated a Federal Reference Method Sampler Number
RFPS-1298-124 in December 1998.
SAFETY
The PQ100 should only be operated as described and for its intended use.
Because the PQ100 runs primarily from battery power, all of the typical hazards
associated with high voltages and internal A.C. wiring have been reduced or
eliminated. Personal injury, damage to the instrument, or fire can occur if the
following electrical precautions are not observed:
• Caution should always be given when attaching the A.C. mains power
connection. Do not attempt to connect main power if the plug or wire are
cracked or frayed.
• Do not attempt to connect main power if the power cord, leads, or outlet
are wet. Do not immerse power cords in water or other liquids.
• Place power cords away from traffic and do not allow anything to rest on
them during operation.
• Do not overload AC outlets.
• Do not attach improperly wired external batteries, solar panels or power
sources.
• Do not open the control panel or handle any other of the electrical parts
while power is applied to the PQ100. Always disconnect the power supply
first.
In addition, personal injury or damage to the instrument could occur if the following
precautions are not observed:
• Always operate the PQ100 in a normal, upright position. The legs should
be bolted down to prevent tipping in conditions of high winds.
• Do not operate the PQ100 if any of the parts are defective, damaged, or
missing.
