INTRODUCTION

1-2.

The

HP

4440B

Decade

Capacitor

is

a

high-

accuracy

instrument

providing

usable

capacitances

from

40pF

to

1.25F.

150.

25%

accuracy

makes

it

an

ideal

aid

in

circuit

design,

ac

bridge

measurements,

and

any

application

where

accuracy

is

critical,

such

as

a

working

standard.

The

4440B

is

also

ideally

suited

for

production

line

testing.

1-3.

The4440B

offers

simplicity

of

operation

combin-

ing

four

easy-to-read

decade

ranges

in

a

lightweight,

compact

package

designed

for

operator

convenience

and

speed.

The

use

of

silvered-mica

capacitors

in

all

decade

steps

providesfor

high

accuracy,

low

dis-

sipation

factor,

and

good

temperature

coefficient.

An

air

capacitor

vernier

provides

100pF

of

additional

capacitance

with

2pF

resolution

between

the

100pF

steps

of

the

smallest

decade.

The

capacitors

are

housed

in

a

double

shield,

such

that

the

increased

capacitance

from

three-terminal

connection

to

two-

terminal

connection

is

held

to

ipF.

UNPACKING

AND

INSPECTION

2-4,

If

the

shipping

carton

is

damaged,

ask

that

the

carrier's

agent be

present

when

the

instrument

is

un-

packed.

Inspect

the

instrument

for

damage(scratches,

dents,

broken

knobs,

etc.).

If

the

instrument

isdam-

aged

or

fails

to

meet

specifications,

notify

the

carrier

and

the

nearest

Hewlett-Packard

Field

Office

(see

Retain

the
