INTRODUCTION.

The Hewlett-Packard

Model

3480A/B Multifunction

Digital Voltmeter may be equipped with Option 005 Data

Storage.

to 50 complete

DVM

readings may be entered

into Data Storage at up to 1000 readings per second. The

output

these stored readings may be governed by an

external device. Data Storage

ideal for use with a digital

recorder where readings may be taken at high speed, stored,

then outputted at 10 to

lines per second.

1-3. Each stored reading includes

all

information generated

by the 3480A/B including input voltage magnitude, range,

function, polarity, and overload. The number

readings

stored

selectable up to 50.

When

stored readings are

outputted, two additional digits are added

identify the

reading number.

All

output lines are isolated from the

3480A/B input terminals.

1-4. Option 005 Data Storage includes Isolated

BCD.

When

Data Storage

disabled, the output

the 3480A/B

becomes identical to that

Isolated

BCD.

1-5. The 3480A/B offers a wide variety

plug-in units

which may be used with Data Storage. These plug-ins

include the 3481 A with a single 10 V

range, the 3482A

with 5

ranges, the 3484A with 5

ranges, 5 true rms

ranges and 6

ranges and the 3485A with up

50 input

channels plus 3

ranges.

1-6.

Any

the above capabilities including Data Storage

may

purchased in a self-contained data logger, the

2070A, which includes the 3480A Multifunction

DVM,

the

5055A Digital Recorder plus any 3480 plug-in. A special

rear panel includes the major Data Storage control lines in

the form

easy

use switches.
