PERFORMANCE

TESTING

1.1

Introduction:

This

test

procedure

is

based

on

the

factory

Quality

Assur-

ance

Final

Test

Procedure,

but

it

is

not

identical,

and

need

not

necessarily

be

performed

in

the

exact

order

in

which

the

tests

are

listed.

However,

the

troubleshooting

guide

in

section

2.0

corresponds

sequentially

to

the

performance

tests

as

far

as

the

type

of

trouble

symptoms

which

may

be

encountered.

Sample

traces

of

tests

which

include

a

writer

print-out

are

provided

in

section

10.0

as

an

aid

for

diagnosis

of

prob-

lems.

Some

of

these

traces

were

derived

using

the

10-Lead

Bio-Tek

Model

ECG-1

Simulator.

If

a

different

simulator

is

used

for

performance

testing

the

operator

must

be

familiar

with

the

correct

waveform

output

of

the

type

used.

If

it

is

necessary

to

perform

the

transmit/receive

tests,

then

another

ELI-200

which

is

fully

functional

is

required.

For

the

direct

transmit/receive

tests,

this

unit

must

be

available

at

the

servicing

site,

along

with

the

proper

interconnect

cable.

For

the

modem

transmit/receive

tests,

however,

the

unit

used

for

test

may

be

located

at

a

remote

installation.

any

time

the

the

board

assembly,

the

AC

or

the

are

removed

and
