Your

John

Fluke

Model

8024B

is

a

pocket-size

digital

multimeter

that

is

ideally

suited

for

application

in

the

field,

laboratory,

shop,

or

home.

Some

of

the

features

of

your

instrument

are:

FUNCTIONS:

All

standard

VOM

measurement

functions

--

ac/dc

voltage,

ac/dc

current,

resistance

--

plus:

Conductance:

A

new

multimeter

function

that

allows

fast,

accurate,

noise-free

resistance

measurements

up

to

10,000

MQ.

Temperature:

Used

with

a

K-type

thermocouple,

this

function

provides

direct

display

in

degrees

Celsius

for

K-type

thermocouples.

Peak-Hold:

Provides

short-term

memory

for

capturing

the

peak

value

of

transient

ac or

dc

signals

such

as

motor

starting

current.

Continuity:

Provides
