2. Description
The spectrum tube power supply unit is intended
for the operation of spectrum tubes U41810 to
U41825. It provides for undisturbed and constant
illumination and increases the lifespan of the tubes
themselves. A clamp with a spring clip ensures that
spectrum tubes can be safely mounted and make
good contact. Full insulation of the clamps and a
protective window ensure safe operation.
The spectrum tube power supply unit with order
number U418001-115 is designed for a mains volt-
age of 115 V (±10%) while the version with order
number U418001-230 is for 230 V (±10%).

supply, snap it into the lower tube clamp with
the spring clip.
• Push the tube gently downwards and fasten it
in place with the upper clamp.
• Close the protective window.
• Turn on the spectrum tube power supply.
• Use a spectroscope/spectrometer to observe
the spectral lines.
• Before removing the spectrum tube, turn off
the tube power supply and allow the tube to
cool.
• Open the protective window.
• Push the tube gently downwards and slip it out
of the upper clamp.
5.2 Changing the fuse
