Power

 

The

 

meter

 

is

 

powered

 

by

 

one

 

9V

 

battery

 

located

 

in

 

the

 

meter

 

handle.

 

Refer

 

to

 

the

 

Maintenance

 

section

 

for

 

replacement

 

instructions.

 

The

IR

 

Surface

 

Temperature

 

Measurements

 

The

 

IR267

 

thermometer

 

remotely

 

measures

 

the

 

surface

 

temperature

 

of

 

an

 

object.

 

The

 

emissivity

 

must

 

be

 

properly

 

set

 

to

 

obtain

 

optimum

 

accuracy

 

(see

 

the

 

Emissivity

 

section

 

for

 

details).

 

1.

 

Hold

 

the

 

meter

 

by

 

the

 

handle

 

grip

 

and

 

pull

 

(and

 

hold)

 

the

 

trigger

 

to

 

power

 

the

 

meter.

 

Use

 

the

 

arrow

 

button

 

to

 

select

 

the

 

O

 

(object/surface)

 

mode

 

if

 

necessary.

 

Scan

 

the

 

surfaces

 

under

 

test;

 

the

 

symbol

 

S

 

(scan)

 

blinks

 

while

 

scanning.

 

Refer

 

to

 

the

 

Field

 

of

 

View

 

section

 

for

 

distance

target

 

(spot)

 

ratio

 

considerations.

 

2.

 

Aim

 

the

 

laser

 

pointer

 

approximately

 

a

 

half

 

inch

 

below

 

a

 

specific

 

point

 

of

 

interest.

 

3.

 

Release

 

the

 

Trigger;

 

the

 

symbol

 

H

 

will

 

appear

 

and

 

the

 

reading

 

(larger

 

digits

 

at

 

center

 

of

 

display)

 

will

 

hold

 

for

 

10

 

seconds,

 

after

 

which

 

the

 

meter

 

will

 

automatically

 

shut

 

off.

 

4.

 

Note

 

that

 

the

 

smaller

 

digits,

 

lower

 

right,

 

reflect

 

the

 

MIN

MAX

AVG

 

or

 

DIF

 

reading

 

as

 

selected

 

in

 

the

 

Settings

 

mode.

 

5.

 

The

 

meter

 

defaults

 

to

 

the

 

settings

 

in

 

use

 

when

 

the

 

meter

 

was

 

last

 

switched

 

OFF.

   

Ambient

 

(Air)

 

Temperature

 

Measurements

 

The

 

IR267

 

can

 

measure

 

the

 

temperature

 

of

 

ambient

 

air

 

using

 

the

 

recessed

 

temperature

 

sensor

 

located

 

on

 

the

 

front

 

of

 

the

 

meter

 

next

 

to

 

the

 

laser

 

pointer

 

lens.

 

1.

 

Pull

 

and

 

hold

 

the

 

Trigger

 

to

 

keep

 

the

 

meter

 

powered.

 

2.

 

Use

 

the

 

UP

 

or

 

DOWN

 

button

 

to

 

select

 

the

 

A

 

(ambient)

 

mode.

 

3.

 

Hold

 

the

 

meter

 

by

 

its

 

handle

 

grip

 

in

 

the

 

ambient

 

air.

 

4.

 

When

 

finished,

 

release

 

the

 

Trigger;

 

the

 

symbol

 

H

 

will

 

appear

 

and

 

the

 

ambient

reading

 

will

 

hold

 

for

 

10

 

seconds.
