ARBOR SCIENTIFIC Spectrum Tube Carousel System User manual

Introduction to the Apparatus
The Next Generation Science Spectrum Tube
System offers a considerable improvement in safety,
convenience, and tube life over conventional systems.
It consists of a power supply & tube storage unit and a
series of spectrum tubes filled with various gases for
spectral inspection and measurement.
The system is available in two versions, differing in the
style of the power supply & storage unit. In the
Single Tube version, the power supply accommodates
one tube and provision is made in the base for storage
of up to six tubes. In the Carousel version, up to eight
tubes are loaded into the power supply’s tube carousel
and the tube to be energized is selected by rotating the
carousel until the required tube reaches the energizing
station.
The spectrum tubes in the Spectrum Tube System
offer extended life by having no internal electrodes and
are protected against accidental breakage by a hard
polymer shell. The Single Tube Power Supply’s electrical
parts are enclosed and a magnetic interlock system
prevents application of the energizing voltage to the
tube contacts unless a tube is correctly inserted. In the
Single Tube version, the height of the tube above the
bench can be adjusted to accommodate the differing
heights of the inlet slits of the various models of
spectrometer in current use.

Operation
CAUTION! THIS UNIT IS SUITABLE FOR OPERATION IN
DRY LOCATIONS ONLY! THE TUBE BECOMES HOT IN
OPERATION! DO NOT TOUCH THE HOT TUBE!
Inserting a tube
Tubes can only be inserted into the carousel at one
location. To ensure correct orientation of the tube in the
tube well, the tube shell has a ridge along the front right
side.
Rotate the carousel unit an empty location aligns with
the tube insertion aperture.
Inserting a tube
Match the ridge on the tube shell to the insertion
aperture on the top of the power supply. The round
magnet cover on the rear of the shell should be facing
down.
End of tube - back view
Insert the lower end of the tube into the insertion
aperture and slide the tube all the way down into the
well so that it seats in the recess at the bottom of the
well.
Load up to eight tubes in this way. The unit may be
operated safely with one or more tube locations empty.
Turning on
The back of the power supply carries the power input
socket, the fuse, and the on/off switch.
Insert the output connector of the wall mount power
supply into the main power supply input socket.
Insert the wall mount power supply into a 110 V AC
electrical outlet.

Rotate the carousel until the desired tube is at the
energizing station located in the front of the unit.
Turn on the power switch. The discharge will now strike
and run.
Changing the selected tube
The selected tube may be changed without turning the
power supply off. Simply rotate the carousel (holding
the partition between stations) until the new selection
is in the energizing station.
DO NOT TOUCH THE HOT TUBE THAT HAS JUST BEEN
RUNNING!
The previously selected tube will be automatically
turned off and the new tube will be energized. The
supply contacts are not energized if an empty location
is at the energizing station.

Removing the tube
To remove a tube, rotate the carousel until the tube to
be removed aligns with the tube insertion aperture. The
tube can then be removed by placing a finger under the
top ledge of the illuminated area and lifting the unit until
its top can be grasped from above and lifted out.
ALWAYS ALLOW A HOT TUBE TO COOL BEFORE
REMOVING IT, BECAUSE OF THE DANGER OF BURNS.
Use with Digital Spectrometers
An accessory for holding the end of a fiber optic digital
spectrometer probe in place in front of the spectrum
tube is available separately. Consult your distributor.
Maintenance
The system needs no special maintenance. It should
be stored in a dry, dust-free environment. For repairs
or replacement parts, contact us. Do not return any
item without prior authorization from us. Replacement
spectrum tubes are available.
