(2).Locating

a hot spot:Aim the

thermometer outside the area

of interest.

Scan across the area in an up and

down motion until the

hot

spot

is

located

while

holding the activation

trigger. The thermometer

will

continue to read the surface temperature

while the activation trigger

is

depressed.

Note : Holding

the trigger

should

last

about

1 second at

least.

2. How it works

Any object

radiates infrared energy

if its temperature

is

above

absolute

zero. This energy travels

at the speed of

light in all directions.

An

infrared

temperature lens collects and

focuses the infrared energy

onto

a sensor

produces

a small

voltage output,

proportional

to the target

temperature,

which is

processed

and displayed.

Cautions

The infrared thermometer

should be

protected

from the following:

o

Electro Magnetic Fields(created

by arc welders, induction heaters and

similar

items)

o

Thermal

Shock

(created

by large or abrupt ambient temperature changes.

Allow 30minutes for

unit to stabilize before use.)

o

Do not leave

the unit on or near objects of high temperature.

Field of View

The

farther the thermometer is from the target, the larger the target

area

will

be. This relationship between distance and target size is

normally expressed

as

the distance to

spot, or

D:

S

ratio.

At

a distance of 10 feet, the

"target "spot

would be 1 foot in diameter.

The thermometer will display the average temperature

across the

target area.
