Detector

 

 

CAUTION:

 

Remove

 

test

 

leads

 

from

 

meter

 

before

 

attempting

 

NCV

 

tests.

 

Always

 

verify

 

the

 

NCV

 

function

 

on

 

a

 

known

 

live

 

circuit

 

before

 

performing

 

tests.

 

Do

 

not

 

use

 

the

 

NCV

 

function

 

if

 

the

 

display

 

does

 

not

 

show

 

EF

 

when

 

the

 

function

 

switch

 

is

 

turned

 

to

 

the

 

NCV

 

position.

 

If

 

the

 

meter

 

does

 

not

 

switch

 

on

 

when

 

the

 

NCV

 

mode

 

is

 

initiated,

 

please

 

check

 

the

 

batteries.

 

With

 

the

 

meter

 

on

 

and

 

switched

 

to

 

the

 

NCV

 

mode,

 

holding

 

the

 

front

 

tip

 

of

 

the

 

clamp

 

jaw

 

near

 

a

 

live

 

electrical,

 

electromagnetic,

 

or

 

electrostatic

 

field

 

causes

 

the

 

beeper

 

to

 

sound,

 

the

 

display

 

to

 

shows

 

dashes,

 

and

 

the

 

red

 

LED

 

lamp

 

to

 

flash.

 

The

 

threshold

 

is

 

100V.

 

The

 

greater

 

the

 

field

 

strength

 

the

 

greater

 

the

 

number

 

of

 

dashes

 

and

 

the

 

faster

 

the

 

rate

 

of

 

the

 

audible

 

beeps

 

and

 

the

 

flashing

 

LED

 

lamp.

 

If

 

the

 

meter

 

does

 

not

 

emit

 

a

 

tone

 

or

 

display

 

dashes

 

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

 

access

 

the

 

Non

Contact

 

Voltage

 

Detect

 

mode.

 

2.

 

Note

 

the

 

voltage

 

detection

 

display

 

icon

 

NCV

 

and

 

the

 

larger

 

EF

 

display.

 

If

 

these

 

displays

 

are

 

not

 

seen

 

when

 

the

 

NCV

 

mode

 

is

 

accessed

 

do

 

NOT

 

attempt

 

to

 

use

 

the

 

meter.

 

Check

 

the

 

batteries

 

and

 

try

 

again.

 

If

 

the

 

meter

 

still

 

does

 

not

 

switch

 

on

 

when

 

the

 

NCV

 

mode

 

is

 

accessed

 

please

 

have

 

the

 

meter

 

serviced

 

or

 

replaced.

 

3.

 

Place

 

the

 

meter

 

near

 

a

 

source

 

of

 

electrical

 

energy.

 

The

 

front

 

tip

 

of

 

the

 

clamp

 

offers

 

the

 

highest

 

sensitivity.

 

4.

 

Note

 

the

 

audible

 

beeping,

 

the

 

dash

 

displays,

 

and

 

the

 

flashing

 

LED

 

lamp

 

when

 

an

 

electrical

 

or

 

electromagnetic

 

field

 

of

 

at

 

least

 

100V

 

is

 

sensed.

 

Note

 

that

 

electrostatic

 

energy

 

will

 

trigger

 

the

 

NCV

 

detector,

 

this

 

is

 

normal.
