10 Cone-Fire / Ramp-Hold
Editing the Target
Temperature
While the kiln is firing, you can change the target tem-
perature. You can edit only the segment that is firing. So if
the first segment is the current one, you can edit only the
first segment. To edit other segments, wait until the firing
has progressed to those segments.
Even if the current segment has already started its hold
time, you can still edit the segment's target temperature.
The controller will go back out of hold and fire to the new
target temperature at the original rate. (You cannot edit
the rate, however.)
During a Ramp-Hold firing, press the
re-
peatedly until
appears.
Press
. The target temperature for the cur-
rent segment will appear.
Use the arrow keys to change the target tempera-
ture.
Press
. The normal kiln temperature will ap-
pear.
The Alarm
While the kiln is firing, you can set the alarm, which
sounds when the kiln reaches the alarm temperature. Use
the alarm as a reminder to look at the glass during fusing or
slumping, to look at witness cones, to close the lid from
vented position, etc.
You can enter only one alarm temperature at a time.
However, after the alarm beeps, you can set the alarm for
another temperature,as many times as you want, during the
firing. Entering an alarm temperature automatically erases
the previous alarm temperature.
Note:
The alarm temperature that you set during a fir-
ing must be higher than the current display tempera-
ture. The alarm is designed for higher temperatures
and not for cooling temperatures.
During a Cone-Fire or Ramp-Hold firing, press
the
repeatedly until
appears.
Press
. The current alarm temperature will
appear.
Use the arrow keys to change the alarm tempera-
ture.
Press
. The normal kiln temperature will ap-
pear.
To silence the alarm when it sounds, press any key.
Note:
If you do not want to use the alarm, set the alarm
temperature to 32°F / 0°C. This setting will turn off the
alarm feature.
Advanced
Features
Skip Segment and Temperature Edit work only in
Ramp-Hold firings. Add Hold Time and Alarm work in
both Cone-Fire and Ramp-Hold firings.
Skip Segment
Skip Segment jumps the firing from the current segment
to the next one.
During a Ramp-Hold firing, press the
.
will appear.
Press
. The current segment ramp or hold
number will appear.
Press
again. (If you change your mind and
don’t want to skip that segment, don’t press
after
appears. The firing will continue in the
same segment and the temperature will appear af-
ter one minute.)
Skip Segment skips to the ramp of the next segment from
either a ramp or hold of the current segment. (Skip Seg-
ment does nothing during the final segment. To end the fi-
nal segment, press
.)
Skip Segment Example
You have pro-
grammed a target temperature of 1425°F for glass fusing,
followed by a segment for controlled cooling. Watching the
glass through the peephole, you notice that the glass edges
have rounded nicely at 1315°. Use Skip Segment to end the
firing segment and to begin the one for slow cooling.
Note:
Make a note of the temperature at which the
glass fused. Program that temperature for the next fir-
ing of that type of glass.
Add Hold Time
Add Hold Time adds 5 minutes to a hold. It is designed
for ceramists who watch witness cones and for glass artists
who inspect the glass near the end of firing.
During a Cone-Fire or Ramp-Hold firing, press
the
repeatedly until
appears.
Press
. The hold time for the current seg-
ment will appear.
Press the
. Each time you press the
, the hold time will increase by 5 minutes.
Press
. The normal temperaturewill appear.
Note:
Add Time will add 5 minutes to a hold even if no
hold had been programmed.
