When to replace optical grating for 2487 and 2489.

When replacing the deuterium lamp, lamp’s power is low and cannot pass the self-test, now we need to replace the lamp housing. Further, if the lamp still cannot pass the self-test after replacing the lamp, we are supposed to replace M1 mirror. Then if the above solution fails, we should replace the optical grating.
The solution is as above when there is a problem that baseline noise is large.
