After assay is completed and before a cuvette is used again, the system washes the cuvette and measures the lamp energy voltage.

If the lamp energy is too high, the system does the following:

1. Stops aspirating additional samples.

2. Displays a warning message to alert the operator.

3. Skips the affected cuvette and performs the assay in the next acceptable cuvette.

4. Flags the last assay result obtained from the affected cuvette with the letter S.

If the lamp energy from a cuvette is less than a preset limit at any of the
14 wavelengths, the system does the following:

1. Displays a warning message to alert the operator.

2. Skips the affected cuvette and performs the assay in the next acceptable cuvette.

3. Flags the last assay result obtained from the affected cuvette with the letter S.

If more than 5 consecutive low lamp energy errors occur, the system does the following:

1. Stops aspirating additional samples.

2. Displays a warning message to alert the operator.

3. Skips the affected cuvette and performs the assay in the next acceptable cuvette.

4. Flags the last assay result obtained from each affected cuvette with the letter S.

The occurrence of a major optics problem, such as a lamp failure, results in the failure of the system to find a cuvette in which to run the assay. If it skips more than  230 cuvettes, the system displays a warning message to alert the operator, and then performs an emergency stop.
