160 ADVIA 2400 Operator’s Guide
5. Verify the liquid is discharged smoothly from the dilution bowl during priming.
6. If the liquid is increasing without being discharged, a leak exists, an electrode is
incorrectly positioned, or a clog is in the drain system. If the liquid increases,
immediately stop the instrument.
IMPORTANT
If clogging occurs, the most probable cause is that the flow path is clogged inside the
electrode. Remove the Na and K electrodes, and check them by transmitted light to
see whether the flow path is clogged or not. You cannot do this for the Cl electrode
because of its construction. When in doubt, even if you cannot find a problem, try
replacing the electrode.
7. Mount the stainless steel cover on the top of the ISE unit by sliding it inside and
fasten the screw retaining the cover.
NOTE:
When sliding it, be careful not to scratch the tubes or dilution bowl. When
fastening the screw, verify that the cover is not caught in the groove and is not loose.
8. Reinstall the cover and tighten the screws.
9. Replace the DPP shield and secure it in place with the Phillips screw.
10. At the ISE Operation window, in the Initialize area, select
Execute
, then select
Yes

Calibrating the ISEs
1. At the Operation Panel, select
Initialize
.
2. At the Menu Panel, select
Maint
. , then select
ISE Operation
.
3. At the ISE Operation window, in the Calibration area, select
Execute
.
4. When prompted, select
Yes
to execute calibration.
5. If the calibration fails, repeat calibration again and if data continues to be unstable,
perform an electrode wash.
NOTE:
The electrodes may have to stabilize on the system before a successful
calibration is achieved.
6. At the ISE Operation window, select the
Electrode Info
button and enter the new
electrode information.
Storing the reference electrode
1. Remove the reference electrode from the ISE module.
2. Rinse the electrode with deionized water.
3. Place it into an appropriate container.
4. Cover the reference electrode with reference electrode filling solution.
5. Cover the container and store at 2 - 40°C (35.6 - 104°F).
6. When ready to use, rinse the electrode with deionized water.
NOTE:
If the electrode is stored cold, allow time for it to equilibrate to room
temperature before use.
