After about one minute slowly slide the samples into the tube at a rate of about 25
mm per minute to make contact with the control thermocouple sheath. See fig 13c.
Once the sample is in position allow a couple of minutes for the cones to burn off
before closing the door, this will allow any vapours given off by the cones to dis-
sipate out of the tube and reduce contamination of the rear end plug and the view-
ing window. See section 5.5.
Note
: It is possible to crack the work tube by inserting samples too quickly. Work
tube failures are not covered by Carbolite Gero's guarantee.
Warning: Do not use the furnace if the work tube is cracked as there is a risk of
exposure to carbon monoxide gas. see section 1.2.
3. Close the furnace door and secure using the two swing bolts. It is important that
the swing bolts are tightened evenly to create a gas tight seal between the door
flanges.
Caution
: To allow the door side shaft to slide in and out, some clearance is
required in the door mechanism; consequently there is a small radial movement in
the door slide arm when the door arm is pushed in towards the work tube. Because
of this radial movement it is possible for the door plug to contact the work tube
from seal assembly if the door handle is lifted as the door arm is pushed inwards:
take care to avoid this happening.
Warning
: Do not operate the furnace with the door or window 'O' ring seals
removed. See fig 17. This will result in high levels of carbon monoxide leaking from
the work tube. see section 1.2.
4. Over-Temperature Alarm
Should a fault develop in the control system which causes the furnace to exceed its
1600 °C limit an over-temperature controller automatically shuts down the furnace
and the over-temperature warning light illuminates on the furnace control panel.
See fig 11a. The over-temperature controller is mounted inside the furnace case
and is not accessible to the operator. Turning the instrument switch off and then on
again once the furnace has cooled down will reset the over-temperature control.
Note
: The over-temperature control is a safety device to protect the furnace in the
event of a fault. If the over-temperature control has operated it is an indication
that there is a fault present in the furnace, it is recommended that the furnace is
not used until the fault has been rectified. Contact our local distributor or our ser-
vice division at the address shown at the back of this manual.

Introduction to the CAF Test Software
The CAF G5 test software is designed to capture images from the digital camera
mounted on the front of the furnace and store them in sequential order. Whether
automatic analysis, manual analysis or mixture of both is preferred the method of
image capture is always the same. Each image captured displays the date, time and the
temperature at which the image was recorded and an optional sample identification.
Test images are stored in a folder file name of your choice, which is entered at the start
of the test and each individual image is recorded with the date, time, temperature and
sequence number and can be played back for analysis of the test samples.
Once the images have been captured the analysis of the results can be carried out by
either an automatic or manual method:
