The

Stroboscope

Type

4913 plus

its

associated

Lamp

Unit

US 0008

are

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).

For

safe

operation

avoid

use in

environ-

ments

containing

volatile

gasses

and

liquids.

Also

verify

that

the 4913 is

set

to

match

the

available

supply

voltage

and

that

the

correct

fuse is

installed

before

each use

of

the

instrument.

To

facilitate

easy

adjustment

of

its

controls,

the

4913 is

generally

best

employed

close

to

the

subject

to

be

investigated.

For

this

purpose

a flat,

vibration

free

surface

should be

chosen

where

it

may

be

used

free-standing

without

risk

of

it

falling

into

operating

machinery

or

of

its

lamp

cable

becoming

entangled

with

machine

parts.

To aid

viewing

of

the

instrument

,

its

front

may

be

raised

by

folding

down

the

metal

stand

attached

to

its

front

feet.
