Vernier Spectrum Tube Carousel Power Supply - Manual (Page 3)

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 (see picture).
1. Rotate the carousel until an empty location aligns with
the tube insertion aperture.
2. 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.
3. 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 (see picture).
4. Load up to eight tubes in this way. The unit may be
operated safely with one or more tube locations empty.
Apply Power
The back of the power supply carries the power input socket, the fuse, and the on/off switch
(see picture).
1. Insert the output connector of the wall mount power supply into the main power supply
input socket.
2. Insert the wall mount power supply into a 100-240 VAC electrical outlet.
3. Rotate the carousel until the desired tube is at the energizing station located at the front of
the unit (see picture).
4. Turn on the power switch.
The discharge will now strike and run.
Changing the 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. CAUTION: 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 (see picture). CAUTION: Always allow a hot tube to cool before
removing it, because of the danger of burns.
