1. Safety instructions
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.
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 parame-
ters.
When the tube is in operation, the terminals of
the tube may be at high voltages with which it is
dangerous to come into contact.
• Only use safety experiment leads for con-
necting circuits.
• Only change circuits with power supply
switched off.
• Set up or dismantle the tubes only when the
power supply unit is switched off.
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 compliance with the EC directive on electro-
magnetic compatibility is only guaranteed when
using the recommended power supplies.
