Question

Dear colleagues, our Cary 4000 has failed, after passing the tests, we decided that it was a deuterium lamp. After replacement deuterium and halogen lamps, when starting up Cary 4000 displays a message: Error code :9:9406CHG: E9406 Source datum not found Fault reported by the instrument software. Fault reported by positional sensor on the filter wheel. What does it mean?
