5. Verify that the guages indicate thier set values and are stable.

6. Select tube loading. For a Mo tube use 50kV and 20mA. Turn the KV's up first with mA's following. Take about 30-60 seconds to turn up each dial.

7. Follow the procedure outlined in the Safety Plan marked as Single Crystal Diffractometer Operating Procedure.
