* Check that things are working, by reading out the CCD by selecting ''Read CCD'' from the ''CCD'' drop-down menu at the top right of the QUARTZ window. This will display information regarding the bias reading and the maximum CCD count.
* Select “Filter” → “Init” at start of run, and again before every filter change
=='''2.2 Setting prism position & determining wavelength range '''==
Do this at the start of the run, using options available by clicking on the “Init” button at the top right of the QUARTZ window:
1) Select “Init” → “Find reference” and wait for “Finding reference...” window to close
2) Select “Init” → “Define red” or “Define blue” depending on the prism you wish to use and enter prism position
3) Select “Init” → “Red/blue position go” and wait for “prism movement” and “detector motion” messages to clear
4) Check and note down the prism position in the “Prism” status box at the bottom of the QUARTZ window.
5) Take a fibre flat
6) By taking an arc (follow steps 1-2 in Section 3.3), check the resulting orders are correct (see section on reductions software) and spectrograph focus is good (see Section 5).

'''3.2 [Fibre Flats]'''
At the start of an observation, take ~7 fibre flats as follows:
