Detector

 

WARNING

:

 

It

 

is

 

possible

 

for

 

voltage

 

to

 

be

 

present

 

in

 

a

 

circuit

 

even

 

if

 

the

 

meter

 

does

 

not

 

beep

 

or

 

flash

 

the

 

NCV

 

LED

 

lamp.

 

Always

 

verify

 

meter

 

operation

 

on

 

a

 

known

 

live

 

AC

 

current

 

circuit

 

and

 

verify

 

that

 

the

 

batteries

 

are

 

fresh

 

before

 

use.

 

 

When

 

the

 

meter

 

senses

 

an

 

AC

 

Voltage

 

or

 

electromagnetic

 

field

 

>

 

100VAC,

 

the

 

following

 

occurs:

 

 

The

 

audible

 

beeper

 

sounds

 

ON

 

and

 

OFF

 

 

The

 

LED

 

lamp

 

flashes

 

ON

 

and

 

OFF

 

 

The

 

display

 

shows

 

1,

 

2,

 

3,

 

or

 

4

 

dashes

 

The

 

greater

 

the

 

electrical

 

field

 

strength,

 

the

 

faster

 

the

 

rate

 

of

 

the

 

audible

 

beeper,

 

the

 

flashing

 

of

 

the

 

LED

 

lamp,

 

and

 

the

 

number

 

of

 

dashes

 

displayed.

 

If

 

the

 

meter

 

does

 

not

 

emit

 

a

 

tone

 

or

 

flash

 

the

 

LED

 

in

 

this

 

mode,

 

there

 

is

 

still

 

the

 

possibility

 

that

 

voltage

 

is

 

present;

 

please

 

use

 

caution

.

 

1.

 

Turn

 

the

 

function

 

switch

 

to

 

the

 

NCV

 

position

 

to

 

select

 

Non

mode.

 

2.

 

Note

 

that

 

EF

 

is

 

displayed

 

when

 

in

 

this

 

mode.

 

If

 

the

 

EF

 

does

 

not

 

display

 

when

 

the

 

function

 

switch

 

is

 

turned

 

to

 

the

 

NCV

 

position,

 

check

 

the

 

batteries

 

and

 

do

 

not

 

use

 

the

 

meter

 

until

 

EF

 

is

 

displayed.

 

3.

 

To

 

test,

 

place

 

the

 

meter

 

near

 

a

 

source

 

of

 

electrical

 

energy.

 

Note

 

that

 

the

 

tip

 

of

 

the

 

meter

 

offers

 

the

 

highest

 

sensitivity.

 

4.

 

Note

 

the

 

audible

 

beeping,

 

the

 

flashing

 

LED,

 

and

 

the

 

displayed

 

dashes

 

when

 

a

 

source

 

of

 

electrical

 

energy

 

is

 

detected.
