OPERATION WITH FIBRE-OPTIC SOURCE TYPE 4915

4.1. PRELIMINARY

4.1.1. Environment and Handling

Like

the

Stroboscope

Type

4913,

the

Fibre-Optic

Source

Type

4915

is

designed

to

be

operated

in

environments

with

ambient

temperature

from

-10

to

+55°C

(+14

to

131

°F)

and

humidities

up

to

90%

RH

(non-condensing).

Provided

that

the

metal

cabinet

of

the

4915

is

kept

perfectly

dry,

its

Fibre-Optic

Cable

AE

6000

may

be

used

in

wet

environ-

ments

and

liquids

without

impairing

the

operating

safety

of

the

instrument.

On

no

account,

however,

should

it

be

used

in

the

presence

of

volatile

gasses

and

liquids.

4.1.2. Connections and Mounting

22

For

operation

of

the

4915

together

with

the

4913,

disconnect

the

Lamp

Unit

US 0008

from

the

4913 and

connect

its

LAMP

OUTPUT and

SIGNAL

OUTPUT

sockets

with

the

LAMP

INPUT

and

SIGNAL

INPUT

plugs

of

the

4915. The 4915

can

be

used

either

free-standing

on

its

four

plastic

feet

or,

for

better

viewing,

its

front

may

be

raised

by

folding

down

the

metal

stand

attached

to

its

front

feet.
