Safety

 

Information

 

To

 

ensure

 

the

 

safe

 

operation

 

and

 

service

 

of

 

the

 

meter,

 

follow

 

these

 

instructions

 

closely.

 

Failure

 

to

 

observe

 

warnings

 

can

 

result

 

in

 

severe

 

injury.

 

 

WARNINGS

 

WARNINGS

 

identify

 

hazardous

 

conditions

 

and

 

actions

 

that

 

could

 

cause

 

BODILY

 

HARM

 

or

 

DEATH.

 

 

When

 

handling

 

test

 

leads

 

or

 

probes,

 

keep

 

hands

 

and

 

fingers

 

behind

 

the

 

finger

 

guards

 

at

 

all

 

times.

 

To

 

avoid

 

electrical

 

shock

 

do

 

not

 

touch

 

exposed

 

electrical

 

wire,

 

connectors,

 

unused

 

input

 

terminals,

 

or

 

circuits

 

under

 

test.

 

 

Remove

 

test

 

leads

 

from

 

the

 

meter

 

before

 

opening

 

the

 

battery

 

compartment

 

or

 

meter

 

housing.

 

 

Use

 

the

 

meter

 

only

 

as

 

specified

 

in

 

this

 

User

 

Guide

 

or

 

accompanying

 

Quick

 

Start

 

to

 

avoid

 

compromising

 

the

 

protections

 

provided

 

by

 

the

 

meter.

 

 

Be

 

sure

 

to

 

use

 

the

 

proper

 

terminals,

 

switch

 

positions,

 

and

 

ranges

 

when

 

taking

 

measurements.

 

 

Verify

 

the

 

meter’s

 

operation

 

by

 

measuring

 

a

 

known

 

voltage.

 

Have

 

the

 

meter

 

serviced

 

if

 

the

 

meter

 

responds

 

unusually

 

or

 

if

 

there

 

are

 

questions

 

regarding

 

the

 

meter’s

 

functional

 

integrity.

 

 

Do

 

not

 

apply

 

more

 

than

 

the

 

rated

 

voltage,

 

as

 

marked

 

on

 

the

 

meter,

 

between

 

terminals

 

or

 

between

 

any

 

terminal

 

and

 

earth

 

ground.

 

 

Do

 

not

 

measure

 

voltages

 

above

 

1000VDC

 

or

 

600V

 

AC

 

between

 

terminal

 

and

 

ground

 

to

 

prevent

 

electrical

 

shock

 

and

 

damage

 

to

 

the

 

Clamp

 

meter.

 

 

Use

 

caution

 

working

 

with

 

voltages

 

above

 

30

 

VAC

 

RMS,

 

42

 

VAC

 

peak,

 

or

 

60

 

VDC.

 

These

 

voltages

 

pose

 

a

 

shock

 

hazard.

 

 

To

 

avoid

 

misleading

 

readings

 

that

 

could

 

lead

 

to

 

electric

 

shock

 

and

 

injury,

 

replace

 

the

 

batteries

 

as

 

soon

 

as

 

the

 

low

 

battery

 

indicator

 

is

 

displayed.

 

 

Disconnect

 

power

 

to

 

the

 

circuit

 

under

 

test

 

and

 

discharge

 

all

 

high

voltage

 

capacitors

 

before

 

testing

 

resistance,

 

continuity,

 

diodes,

 

or

 

capacitance.

 

 

Do

 

not

 

use

 

the

 

meter

 

in

 

the

 

presence

 

of

 

explosive

 

gas

 

or

 

vapor.

 

 

To

 

reduce

 

risk

 

of

 

fire

 

or

 

electric

 

shock,

 

do

 

not

 

use

 

the

 

meter

 

if

 

it

 

is

 

wet

 

and

 

do

 

not

 

expose

 

the

 

meter

 

to

 

moisture.

 

 

Individual
