To set up the Sample Rack(s), select any of the supplied racks other than the color-coded
racks. Insert the desired User Number Card as a Command Card onto the rack as described
above. Continue to make other Sample Racks by placing a User Number Card in the slot.
Place a Rack Number Card on the racks with User Number Cards and any other racks you
will use for counting samples. Refer to Section 3.2 for more information on using the Sample
Racks.
Installing the Racks
For counting, the racks are placed in the sample changer (the bed of the instrument which
transports the samples). The racks are moved in a counter-clockwise motion. The vials are
counted when the rack has reached the right rear position where the elevator that moves the
vial into the counting chamber is located.
To install a rack, hold it so that the molded position numbers are toward you, and the cards
(if any) face away from you. Place the rack on the right side of the sample changer, inserting
it at an angle so that the lip on the left end slides under the groove along the middle of the
sample changer. See Figure 2.6. After installing the rack, push it away from you, toward the
back of the sample changer where the elevator is located.
Since the racks are moved in a counter-clockwise direction, the second and successive racks
are installed progressively toward the front of the instrument. When the right-hand side of
the sample changer is filled, load additional racks on the left-hand side, front to rear. The
racks on the left side are also loaded with the molded numbers toward you, cards (If any)
away from you. Slide the lip on the left end of the rack under the groove along the left side of
the sample changer.
2.5 Preparing the Printer
The printer is set up at the time of installation by your Beckman Service Representative.
Details of the printer operation are provided in the printer manual that was delivered with
your instrument.
