5) Open the cassette load door, load the test cassette and close the
cassette load door.
6) Allow the cassette to process and return to the cassette load/unload
door. Remove the cassette.
7) Record the weights of the test tubes placed in test tube slots 1, 3, and 5
using Table 8-1.
• Record the weight of the tube in slot 1 in the Pipettor Low Volume
section under Test tube 1 — After test (A).
• Record the weight of the tube in slot 3 in the Pipettor High Volume
section under Test tube 3 — After test (A).
• Record the weight of the tube in slot 5 in the Diluter section under Test
tube 5 — After test (A).
8) Determine if the Dispenser/Pipettor is performing to specification by
performing the following calculations using Table 8-1:
• In the Pipettor Low Volume section, subtract the weight of tube 1(A)
from the weight of 1(B). The value must be 0.095 g and 0.105 g to be
acceptable.
• In the Pipettor High Volume section, subtract the weight of tube 3(A)
from the weight of tube 3(B). The value must be 0.285 g to 0.315 g to
be acceptable.
• In the Diluter section, subtract the weight of tube 5(B) from the weight
of tube 5(A). The value must be 2.33 g to 2.63 g to be acceptable.
Note: If the values recorded in the tables are not within the recommended range,
call bioMérieux for assistance.
Cleaning Optics (Cards Processing)
This procedure allows you to clean and verify the optics while test cards are
still processing. Use the optics cleaning procedure in Chapter 7 if the
instrument is shut down.
Note: All steps in this procedure must be completed.
CAUTION: Do not wear powdered latex gloves while cleaning the
optics. The gloves that contain a powder can interfere with the
optics
