Dangers, warnings, & cautions
Danger!
Failure to observe the following procedures may result in serious personal injury:

Not for use in Explosive or Hazardous locations. This product is NOT Intrinsically Safe.

Contains built-in lithium ion battery pack. Do not incinerate or dispose of in fire.

Do not disassemble, alter, or re-construct the li-ion battery.

Contains Class 3b visible laser radiation source (658 nm, nominal 5 mW). Do not look directly into

beam or view with telescopic devices.
This instrument will NOT detect natural gas.
Warning!
 Read the manual before operation.
 Do not store in temperatures exceeding 60°C (140°F) and in direct sunlight.
 Do not immerse in liquids.
 The Sensors and batteries in this instrument have limited shelf-life, even if never used.
 Do not disassemble, service, or clean the optical engine internal components while power is applied.
The laser source can hurt you.
Caution!
General
 Condensation may damage your instrument and its sensors.
 A non-condensing environment is required for proper measurements.
 Do not charge batteries outside the range of 0°C to 40°C (32°F to 104°F).
 Battery run-time may be somewhat reduced at lower than 20°C (68°F) temperatures.
Temp/RH/Dew Point
 The internal Temp/RH sensor in this instrument is not designed for use in bright sunlight or in the
presence of a strong radiant heat sources. It is intended primarily for indoor use. It is not equivalent to
a protected dry-bulb thermometer.
PM/dust
 Clean the optical engine mirror with a soft cloth, if it is dirty. Scratches will affect performance.
 Avoid measuring wet particles, fogs, and liquid mists that will tend to cling to the impactor, optical engine,
tubing, and pump surfaces.
 Avoid oily mists as found near some machining operations.
 This monitor is designed to measure dry particulates, not filaments.
 Do not attempt to measure Asbestos with this instrument.
 Keep a "Pump Protection Filter" or other gravimetric filter in place to help prolong the life of the pump.
 You must check & calibrate the flow rate, when using this device as a (gravimetric) sampling pump.
