* If the instrument control and quick-look interfaces are not running, they may be started from the panel on the left edge of the left screen. The instrument control GUI is started with the absorption spectrum icon, and the quick-look GUI from the emission spectrum icon.
* Ensure that the grating you require is inserted(see the Grating Change Instructions), and then set the grating to the required angle.
* Run a Hartmann routine (see the Advanced User Guide) to establish the best focus for the spectrograph.
* Set the required spectrograph camera focus.
* Set the slit width.
* Check that the required filter is in the beam (or left open if required).
* Select the exposure type (ARC, BIAS, SCIENCE, FLAT, TEST).
* If appropriate, set the exposure time and number of exposures.
* Select a target from the target catalogue file so that the object name and coordinates will go into the fits header.* If taking a science image, acquire the target, and ensure that it is visible through the slitand in focus.
* If taking an arc, ensure that the arc mirror is in-beam, and the required arc lamp is on.
* Select the SCIENCE exposure type after taking an arc, this will turn off the arc lamp and remove the arc mirror.
