NOZZLE MAINTENANCE AND PERFORMANCE
6.4 Performing the Volume Test
The Volume Test requires the Nozzle Maintenance Kit.
NOTE:
The Volume Test must be performed weekly.
1 From the Maintenance menu, select
Volume Test
.
2 Hold a Volume Test tube (small tube) to cover the selected nozzle.
3 Press the corresponding reagent prime button to collect the reagent.
NOTE:
With QC/Maintenance tracking enabled, enter the measured volume on
the keypad and press ENTER. With QC/Maintenance Tracking disabled, the
menu returns to the Maintenance menu.
4 Remove and cap the tube.
5 Record the nozzle position on the tube and place the tube in the
appropriate position in the tube stand.
6 Repeat Steps 2 through 5 for each nozzle.
7 Compare collected nozzle volumes with the following table.
Table 12: Volume Test Tolerances
Nozzle/Reagent Line
Minimum
Maximum
A, B, C
9.0 mL
11.0 mL
D
8.5 mL
10.5 mL
NOTE:
The stainer normally functions correctly if nozzle volumes are slightly
higher or lower than the specified range. It is important that the B and C nozzle
volumes are similar, (typically within 1 mL). Spray volumes < 7.5 mL or > 13.0
mL indicate serious problems with the nozzles or reagent delivery lines.
•
If the volume is within the tolerance range, go to Step 9.
•
If the volume is outside the tolerance range:
a. Clear the nozzle orifice with the nozzle brush found in the
maintenance kit.
b. If necessary, remove the nozzle and perform the Nozzle
Cleaning procedure (Section 6.1).
c. If the problem persists, replace the nozzle.
NOTE:
If the problem persists after you have replaced the nozzle, contact
ELITechGroup.
