Cedex Bio System 11 Troubleshooting
Dealing with exceptional situations
The system does not go
to Operating status.
System status There are not enough free
cuvettes on the instrument.
Load empty cuvette segments.
e See Preparing cuvettes on page B-28.
Air/water calibration is
required.
Perform Abs. Air/Water Calibration maintenance
action.
e See Perform an air/water calibration on page C-28.
In the corresponding calibrator
lot definitions of at least one of
the tests you want to perform,
the value for Last Is Water is
Off.
The Last Is Water definition defines what is used as the
zero calibrator. It is either system water (On) or a stan-
dard, usually water (Off), which would be placed in a
tube like any other calibrator.
With some tests, calibration does not work with special
zero calibrators, they need the Last Is Water definition
on.
Possible remedies:
1. Delete the current calibration order and redefine it.
2. If the Last Is Water definition is Off, make sure to
place a special zero calibrator on the instrument
when calibrating. (This is usually water.)
If this does not help change the Last Is Water value to
On. (Calibration for this test does not work with a spe-
cial zero calibrator.)
1. Choose Workplace > Lot Data > Calibrators.
2. Select the entry for the test and expand the entry.
3. Select the Last Is Water entry and press .
4. Press On.
5. Press .
6. Delete the current calibration order and redefine it.
A hardware error had occurred. Some hardware conditions prevent the system from
