The

parameters

which

require

being

set

for

a

particular

detector

are:

Section

1)

Alarm

Point

ILE.1.

2)

Units

ILE.2.

3)

Calibration

Constant

ILE.3.

4)

Detector

Dead

Time

ILE.4.

5)

High

Voltage

ΠΕ.5.

The

last

four

are

preset

at

the

factory

for

the

detector

which

was

purchased

with

the

ESP-1.

The

alarm

point

is

set

at

a

high

value

at

the

factory

and,

thus,

should

be

reset

to

a

user

determined

value

if

it

is

desired

to

use

this

feature

of

the

instrument.

Section

П.Е.

provides

simple

instructions

on

how

to

reset

(recalibrate)

the

items

when

changing

detectors

or

recalibrating

the

instrument.

`

.

The

high

voltage

should

be

checked

or

readjusted

for

a

new

detector,

PRIOR

to

connecting

the

detector.

Failure

to

do

so

may

result

in

damage

to

the

detector.

Calibrations

Required

by

Regulatory

Agencies

Regulatory

agencies

generally

require

routine

laboratory

calibration

of

radiation

survey

instruments

by

an

approved

facility

at

least

once

per

year.

To

have

your

instrument

recalibrated

retum

the

ESP-1

and

detector

to

the

factory

in

Santa

Fe,

to

the

Eberline

repair

facility

in

Columbia,

South

Carolina,

or

to

another

approved

calibration

facility.

If

your

facility

has

been

approved

for

such

calibrations,

this

may

be

accomplished

by

using

the

procedures

given

in

section

V,

"Calibration."

B.

PRELIMINARY

INSTRUCTIONS

24

Upon

recciving

the

ESP-1

perform

the

following

before

proceeding.

1.

Set

Up

the

ESP-1

and

Detector

The

ESP-1

has

an

MHV

connector

on

its

front

surface

for

connection

to

a

radiation

detector.

This

connector

supplics

high

voltage

to

the

detector

and

also

transmits

the

detector

signal

to

the

ESP-1

for

processing

and

display.

If

the

ESP-1

is

already

connected

to

a

'

detector

then

it

is

reasonable

to

assume

that

the

high

voltage

has

been

previously

set.

If

you

are

not

sure

that

the

high

voltage

has

been

properly

adjusted,

disconnect

the

detector

from

the

instrument

by

rotating

the

cable

connector

counterclockwise.

You

can

proceed

through

these

instructions

without

the

detector

being

connected.
