to 1200 °C, the aperture can be set to a suitable position to maximise the exposure
range e.g. f8.
3.9.2
Adjusting the Lens.
To adjust the lens for the ideal image quality the furnace and computer must be
connected, see section 3.10 and the software must be running in configure mode see
section 4.7.2. The image displayed in the image window is a real time image, so the
camera focus can easily be adjusted. The camera must be mounted as described
above.
Prepare a number of test samples and load into the work tube as described in section
4.5. Close the door and ensure it is securely closed using the swing bolts.
For there to be sufficient light in the work tube to allow image capture the furnace must
be either at a standby temperature of 450 °C with rear light activated (if available) or at
a standby temperature of 815 °C.
With the lens set at a suitable aperture, ideally f16 an image should now be displayed in
the software. Loosen the focus locking screw and with the focusing ring at the front of
the lens see fig 5b the image can be focused on the screen. It may be useful to take the
weight of the camera in one hand while focusing with the other. Once the image is
focused on the screen the focus locking screw can now be tightened (care must be taken
not to over-tighten these screws.)
Note
: As the furnace warms up the work tube will increase slightly in length causing the
camera focus to alter, it may be necessary to re-focus the camera during the initial Ash
Fusion test run. Once the camera is focused the focus ring can be locked in position
using the locking screw, unless the camera is disturbed it should not require re-focusing
during subsequent tests.

Computer Connections
Unpack the computer from its transit boxes and assemble in accordance with the
manufacturers instructions provided.
Connect the Ethernet cable from the Ethernet socket on the back of the furnace case to
the Ethernet socket on the back of the computer.
Connect the comms lead from the 'Comms Port' on the back of the furnace to the
comms port on the back of the computer.
Connect the Monitor DVI in lead to the socket on the rear of the computer via the DVI to
display port adaptor.
Connect the keyboard and mouse to a USB socket on the rear of the computer.
