Caution

The DRA should not be plugged in and operated with the instrument set to 0 nm. If it

is, the detectors will be flooded with white light, which will decrease the sensitivity of

the accessory and increase noise. If this should happen, place the DRA in a dark place

for 24 hours to allow it to recover.

5. Remove the front cap from the accessory and observe the diffuser at the

reference port. The image should be centered on the diffuser.

If it is not:

• Check that that DRA is correctly locked down onto the

instrument sample compartment floor.

• If the DRA is correctly installed, and misalignment persists,

contact your local Varian service representative.

6. Replace the sphere cap with the 'S' mark upwards.

7. Tape a card over the diffuser on the reference port to exclude light. Make sure

you do not contaminate the surface of the diffuser.

8. Check the adjustment of the Beam on to mirror M2. If necessary adjust the

horizontal alignment of the beam by loosening the screws on either side of

mirror M1 and rotating it slightly.

9. Fasten the screws.
