CAUTIONS

 

 

Improper

 

use

 

of

 

this

 

meter

 

can

 

cause

 

damage,

 

shock,

 

injury

 

or

 

death.

 

Read

 

and

 

understand

 

this

 

user

 

manual

 

before

 

operating

 

the

 

meter.

 

 

Always

 

remove

 

the

 

test

 

leads

 

before

 

replacing

 

the

 

battery

 

or

 

fuses.

 

 

Inspect

 

the

 

condition

 

of

 

the

 

test

 

leads

 

and

 

the

 

meter

 

itself

 

for

 

any

 

damage

 

before

 

operating

 

the

 

meter.

  

 

Use

 

great

 

care

 

when

 

making

 

measurements

 

if

 

the

 

voltages

 

are

 

greater

 

than

 

30VAC

 

rms

 

or

 

60VDC.

 

These

 

voltages

 

are

 

considered

 

a

 

shock

 

hazard.

 

 

Always

 

discharge

 

capacitors

 

and

 

remove

 

power

 

from

 

the

 

device

 

under

 

test

 

before

 

performing

 

Diode,

 

Resistance

 

or

 

Continuity

 

tests.

 

 

Voltage

 

checks

 

on

 

electrical

 

outlets

 

can

 

be

 

difficult

 

and

 

misleading

 

because

 

of

 

the

 

uncertainty

 

of

 

connection

 

to

 

the

 

recessed

 

electrical

 

contacts.

 

Other

 

means

 

should

 

be

 

used

 

to

 

ensure

 

that

 

the

 

terminals

 

are

 

not

 

"live".

 

 

If

 

the

 

equipment

 

is

 

used

 

in

 

a

 

manner

 

not

 

specified

 

by

 

the

 

manufacturer,

 

the

 

protection

 

provided

 

by

 

the

 

equipment

 

may

 

be

 

impaired.

 

 

This

 

device

 

is

 

not

 

a

 

toy

 

and

 

must

 

not

 

reach

 

children’s

 

hands.

 

It

 

contains

 

hazardous

 

objects

 

as

 

well

 

as

 

small

 

parts

 

that

 

the

 

children

 

could

 

swallow.

 

 

In

 

case

 

the

 

device

 

is

 

going

 

to

 

be

 

unused

 

for

 

an

 

extended

 

period

 

of

 

time,

 

remove

 

the

 

batteries

 

and

 

store

 

them

 

separately.

 

 

Expired

 

or

 

damaged

 

batteries

 

can

 

cause

 

cauterization

 

on

 

contact

 

with

 

the

 

skin.

 

Use

 

protective

 

gloves

 

when

 

handling.

 

 

Do

 

not

 

short

circuit

 

the

 

batteries.

 

Do

 

not

 

throw

 

batteries

 

into

 

a

 

fire.

 

 

This

 

meter

 

has

 

been

 

designed

 

for

 

safe

 

use,

 

but

 

must

 

be

 

operated

 

with

 

caution.

 

The

 

rules

 

listed

 

below

 

must

 

be

 

carefully

 

followed

 

for

 

safe

 

operation.

 

 

1.

 

NEVER

 

apply

 

voltage

 

or

 

current

 

to

 

the

 

meter

 

that

 

exceeds

 

the

 

specified

2.

 

USE

 

EXTREME

 

CAUTION

 

when

 

working

 

with

 

high

 

voltages.

 

3.

 

DO

 

NOT

 

measure

 

voltage

 

if

 

the

 

voltage

 

on

 

the

 

"COM"

 

input

 

jack

 

exceeds

 

600V

 

above

 

earth

 

ground.

 

4.

 

NEVER

 

connect

 

the

 

meter

 

leads

 

across

 

a

 

voltage

 

source

 

while

 

the

 

function

 

switch

 

is

 

in

 

the

 

current,

 

resistance,

 

or

 

diode

 

mode.

 

Doing

 

so

 

can

 

damage

 

the

 

meter.

 

5.

 

ALWAYS

 

discharge

 

filter

 

capacitors

 

in

 

power

 

supplies

 

and

 

disconnect

 

the

 

power

 

when

 

making

 

resistance

 

or

 

diode

 

tests.

 

6.

 

ALWAYS

 

turn

 

off

 

the

 

power

 

and

 

disconnect

 

the

 

test

 

leads

 

before

 

opening

 

the

 

covers

 

to

 

replace

 

the

 

fuse

 

or

 

batteries.

 

7.

 

NEVER

 

operate

 

the

 

meter

 

unless

 

the

 

back

 

cover

 

and

 

the

 

battery

 

and

covers

 

are

 

in

 

place

 

and

 

fastened

 

securely.

 

8.

 

NEVER

 

change

 

the

 

measurement

 

function

 

by

 

turning

 

the

 

function

 

dial

 

while

 

testing.

 

9.

 

If

 

the

 

equipment

 

is

 

used

 

in

 

a

 

manner

 

not

 

specified

 

by

 

the

 

manufacturer,

 

the

 

protection

 

provided

 

by

 

the
