Warning

A Warning identiﬁes conditions and actions that pose ha-

zards 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.

Introduction

Concerning Factory Mutual Approved

Nonincendive Devices:

Operation in Environments that Require

Nonincendive Devices

WARNING

IN HAZARDOUS LOCATIONS DO NOT use serial port con-

nections, change batteries or open serial port cover. To re-

duce 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 thermo-

meter has been tested to standards for preventing explosi-

ons 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 condi-

tions.

This noncontact thermometer has a Factory Mutual Nonin-

cendive 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.
