Warning

A Warning identifies conditions and actions that pose ha­zards to the user. To avoid electrical shock or personal injury,
follow these guidelines:

• Do not point laser directly at eye or indirectly off
reflective surfaces.

• Before using the thermometer inspect the case. Do not
use the thermometer if it appears damaged. Look
for cracks or missing plastic.

• Replace the batteries as soon as the battery indicator
two or less segments.

• Do not use the thermometer if it operates abnormally.
Protection may be impaired. When in doubt, have the
thermometer serviced.

• Do not operate the thermometer around explosive gas,
vapor, or dust.

• Do not connect the optional external probe to live
electrical circuits.

• To avoid a burn hazard, remember that highly reflective
objects will result in lower than actual temperature
measurements.

• Do not use in a manner not specified by this manual or the
protection supplied by the equipment may be impaired.

Caution

To avoid damaging the thermometer or the equipment under
test protect them from the following:

• EMF (electro-magnetic fields) from arc welders,
induction heaters, etc.

• Static electricity

• Thermal shock (caused by large or abrupt
ambient temperature changes- allow 30 minutes
for thermometer to stabilize before use).

• Do not leave the thermometer on or near
objects of high temperature.

The Fluke Model 574 Infrared Thermometer (the
thermometer) is for non-contact temperature
measurement. This thermometer determines
an object‘s surface temperature by measuring
the amount of infrared energy radiated by the
object‘s surface.

Concerning Factory Mutual Approved

Nonincendive Devices:

Operation in Environments that Require

Nonincendive Devices

WARNING

IN HAZARDOUS LOCATIONS DO NOT use serial port con­nections, change batteries or open serial port cover. To re­duce risk of explosion in hazardous locations, use only Fluke
temp probe part 2432508 and do not use other accessories,
such as power supply and cables.

A nonincendive rating (NI) indicates that this infrared thermo­meter has been tested to standards for preventing explosi­ons in hazardous areas by limiting the ability of equipment
to ignite a specifi ed fl ammable gas or vapor-in-air mixture.
Nonincendive equipment is incapable of releasing suffi cient
electrical or thermal energy to ignite fl ammable gases or
vapors under NORMAL operation and environmental condi­tions.

This noncontact thermometer has a Factory Mutual Nonin­cendive rating. The rating from this USA organization reads:
“Nonincendive, Class I, Division 2, Groups A, B, C, D; Class
I, Zone 2 IIC; T4 Ta = 50ºC when used with 1.5V alkaline
batteries.“

A Class I, Division 2 location is a location:

• where volatile fl ammable liquids or fl ammable gases
or vapors exist, but are normally confi ned within
closed containers;

• where ignitable concentrations of gases, vapors or liquids
are normally prevented by positive mechanical
ventilation; or

• adjacent to a Class I, Division 1 location, where ignitable
concentrations might be occasionally communicated

• groups A, B, C, D refers to: Acetylene, Hydrogen,
Ethylene, and Propane.
