Hot cathode tubes are thin-walled, highly evacuated
glass tubes. Treat them carefully as there is a risk of
implosion.
•
Do not subject the tube to mechanical stresses.
If voltage or current is too high or the cathode is at the
wrong temperature, it can lead to the tube becoming
destroyed.
•
Do not exceed the stated operating parameters.
•
Before switching on the anode voltage wait about
1 minute for the heater temperature to stabilise.
When the tube is in operation, the terminals of the
tube may be at high voltages with which it is danger-
ous to come into contact.

1. Safety instructions
•
Only use safety experiment leads for connecting
circuits.
•
Only change circuits with power supply switched off.
•
Do not connect up the terminals on the base until
the tube is fixed into it.
When the tube is in operation, the stock of the tube
may get hot.
•
Allow the tube to cool before putting away the
apparatus.
The tube may only be used with Socket for Fine Beam
Tube TEL U8481435.
The compliance with the EC directive on electromag-
netic compatibility is only guaranteed when using the
recommended power supplies.
