1. Safety instructions

The operating unit for fine-beam tube conforms to

the safety requirements for electrical equipment

for measurement, control and laboratory use of

DIN EN 61010 part 1 and is classified as belong-

ing to protection class I. It is in-tended for opera-

tion in dry rooms that are suitable for electrical

equipment or installations.

Safe operation of the apparatus is guaranteed

with correct handling. However, safety is not

guaranteed if the apparatus is handled improp-

erly or carelessly.

If it is to be expected that safe operation is im-

possible (e.g., in case of visible damage), the

apparatus is to be rendered inoperative immedi-

ately and to be safe-guarded from unintentional

use.

In schools and training institutions, operation of

the apparatus is to be responsibly supervised by

trained personnel.

While the equipment is in operation, voltages

may be present at the tube socket which are

unsafe to touch.

• Never operate the device without a tube in-

serted.

• Never remove or insert tubes while the

equipment is turned on.

• The instrument may only be connected to the

mains via a socket that has an earth connec-

tion.

• Replace a faulty fuse only with one matching

the specifications stated at the rear of the

housing.

• Disconnect the equipment from the mains

before replacing a fuse.

• Never short the fuse or the fuse holder.

• Never cover the air vents in the housing. This

is necessary in order to ensure sufficient cir-

cula-tion of air required for cooling the inter-

nal com-ponents of the equipment.

Hot cathode tubes are thin-walled, highly evacu-

ated glass tubes. Treat them carefully as there is

a risk of implosion.

• Do not subject the tube to mechanical

stresses.

• Before switching on the anode voltage wait

about 1 minute for the heater temperature to

stabilise.

When the tube is in operation, the stock of the

tube may get hot.

• Allow the tube to cool before putting away the

apparatus.
