both in front of and behind the instrument.
Plug the instrument into an outlet of the appropriate
voltage (100 to 240V). Press and hold the power
button for 3 seconds, the instrument powers on.
III. Tube Holder Installation / Exchange:
The instrument includes an assortment of tube
holders. To exchange the tube holders, remove the
rotational bar from the instrument by unscrewing
the thumb screw on the left side. Once fully
loosened the bar can now be removed by pressing it
fully to the right and then lifting the left side
upward. Tube holders can be installed or removed
from the rotational bar by sliding them in either the
left or right direction.
To load test-tubes, press them firmly into the
appropriate holder. ALWAYS ensure a balanced load
across both sides of the rotational axis. (When
mixing 15 and 50ml tubes, always load a similar
quantity of tubes on each side of the rotational axis.)
