SAFETY

Before

connecting

the

instrument

to

a

power

source, care-

fully

read

the

following

information,

then

verify

that

the

proper

power

cord

is

used and the proper line fuse

is

installed

for

power

source. The specified voltage is

shown

near

of

the

AC inlet.

If

the

power

cord is

not

applied

for

specified

voltage, there is

always

a certain

amount

of

danger

from

electric shock.

Line

This instrument operates using ac-power inputvoltages

that

frequencies

from

50

Hz

to

Power

cord

The ground

wire

of

the

3-wire

ac

power

plug places

the

chassis and housing

of

the

instrument

at earth ground. Do

not

attempt

to

defeat

the

ground

wire

connection or

float

the

instrument;

to

do

so

may

pose a great

safety

hazard.

The appropriate

power

cord is supplied

by

an

option

that

is specified

when

the

instrument

is ordered.

The optional

power

cords are

shown

as

follows

in Fig. 1.

ADJUSTMENT

CASE DISASSEMBLY

AND

ASSEMBLY

1. To open

the

case,

turn

the

unit

upside

down

with

the

rubber

feet

facing

up. (See Fig. 2)

2. Remove

the

four

screws

from

the

bottom

case.

3. Carefully separate

the

two

halves

of

the case and

recalibrate

the

unit

following

the

prescribed procedure.

SCREWS

4. To close

the

case,

lower

the

bottom

case and guide

the

front

and rear panels

into

thier

slots. Position

the

rub-

ber

feet

as

illustrated

and

screw

the
