English Warning

Do not point laser directly at eye or indirectly off

reflective surfaces.

Cautions

Use this unit only as specified in this manual or the

protection provided by the unit may be impaired.

All models should be protected from the following,

▲EMF (electro-magnetic fields) from arc welders,

induction heaters

▲Static electricity

▲Thermal shock (caused by large or abrupt ambi-

ent temperature changes—allow 30 minutes for

unit to stabilize before use)

▲Do not leave the unit on or near objects of high

temperature

Introduction

We are confident you will find many uses for your

handheld noncontact thermometer. Compact, rugged,

and easy to use—just aim, press the trigger, and read

surface temperatures in less than a second. You can

safely measure surface temperatures of hot, hazardous,

or hard-to-reach objects without contact.

How it Works

Infrared thermometers measure the surface tempera-

ture of an object. The unit’s optics sense emitted (E),

reflected (R), and transmitted (T) energy, which is

collected and focused onto a detector. The unit’s

electronics translate the information into a temperature

reading which is displayed on the unit. The laser is

used for aiming purposes only.

English

How to Operate the Unit

°C/°F and Battery

Open the battery compartment to access the C/F

switch or to insert/remove the battery. To switch

between °C and °F, toggle the switch (A). Insert the

9v battery positive side first into the battery

compartment.

Operating the Unit

To measure a temperature, point unit at object and

press the On Button. Be sure to consider distance-

to-spot size ratio and field of view. If the unit is

equipped with a laser, use the laser only for aiming.

See ‘How to Accurately Measure Temperatures’.

Display

The backlit LCD displays the current temperature in

Celsius or Fahrenheit. The unit will hold the reading

for 7 seconds after the On Button is released; the word

HOLD appears. The presence of the battery icon

indicates a low battery (B).

Temperature

Locating a Hot Spot

To find a hot spot aim the thermometer outside the

area of interest, then scan across with an up and

down motion until you locate the hot spot.

Field of View

Make sure that the target is larger than the unit’s spot

size. The smaller the target, the closer you should be

to it. When accuracy is critical, make sure the target

is at least twice as large as the spot size.

Distance & Spot Size

As the distance (D) from the object increases, the

spot size (S) of the area measured by the unit

becomes larger.

Reminders

■Not recommended for use in measuring shiny

or polished metal surfaces (stainless steel,

aluminum, etc.). See Emissivity.

■The unit cannot measure through transparent

surfaces such as glass. It will measure the

surface temperature of the glass instead.

■Steam, dust, smoke, etc., can prevent accurate

measurement by obstructing the unit’s optics.

Emissivity

Most organic materials and painted or oxidized surfaces have an emissivity of

0.95 (pre-set in the unit). Inaccurate readings will result from measuring shiny or

polished metal surfaces. To compensate, cover the surface to be measured with

masking tape or flat black paint. Allow time for the tape to reach the same tempera-

ture as the the material underneath it. Measure the temperature of the tape or paint-

ed surface.

Maintenance

Lens Cleaning: Blow off loose particles using clean compressed air. Gently brush

remaining debris away with a camel's hair brush. Carefully wipe the surface with a

moist cotton swab. The swab may be moistened with water.

NOTE: DO NOT use solvents to clean the plastic lens.

Case Cleaning: Use soap and water on a damp sponge or soft cloth.

NOTE: DO NOT submerge the unit in water.
