13.2.3 PICK A PROGRAM
1. You will see
CUS1
,
CUS2
,
CUS3
or
CUS4
.
2. These are the four custom programs.
3. You can scroll to other ones with the
UP
and
DOWN
button.
4. When the display shows the one you want to select
press
ENTER
.
13.2.4 SPECIFY NUMBER OF SEGMENTS
1. Once you have chosen a program, you need to specify
the total number of segments that you will use.
2. All programs consist of 1 or more segments, as shown
in the sample profiles in this manual.
3. Each segment has 3 parts: a ramp rate (speed of
temperature rise in degrees centigrade per hour), hold
temperature (in degrees centigrade), and hold time (in
hours and minutes) at the hold temperature.
4. It is helpful to draw your profile to see how many
segments you will need.
5. Then, use the
UP
and
DOWN
buttons to display the
desired number of segments, and press
ENTER
to
store the value when you see the number you want.
13.2.5 ENTER RAMP RATE
1. You will see
rA1
, followed by a value like
150
.
2. The
rA1
stands for Ramp One.
3. The value represents a rate of temperature rise
expressed in degrees per hour.
4. Use the arrow buttons to adjust the rate and press
ENTER
to store the value.
5. To help you visualize what is typical of various ramps
read the following:
6. Slow rates range from 1-50 degrees per hour, and are
used for thick glass projects.
7. Medium rates range from 60 to 200 degrees per hour,
and are used for thick, hand-built ceramics.
8. Fast rates range from 250–1000 degrees per hour,
and are used for glazes, thin ceramics and small glass
projects.
9. A rate of
9999
sets the kiln to ramp as fast as
possible.
10. Also, see the various ramps in the standard programs
for an idea of what works.
13.2.6 ENTER HOLD TEMPERATURE
1. You will see
oF1
followed by a value like
0300
.
2. The
oF1
stands for Temperature One.
3. For a single segment program, this is the top
temperature of the firing.
4. For multi-segment programs, this can be a temperature
where you want to hold to dry the ware or for carbon
burn-out, or to equalize the temperature across the
item or it can be where you just want to switch ramp
rates without a hold.
5. Adjust the temperature with the
UP
and
DOWN
buttons and press
ENTER
to store the displayed
value.
13.2.7 ENTER HOLD TIME
1. You will see
HLd1
followed by a value like
00:00
.
2. The
HLd1
stands for Hold One.
3. Hours are displayed to the left of the decimal point and
minutes to the right (HH.mm).
4. Use the he
UP
and
DOWN
buttons to adjust the hold
time at the soak temperature.
5. Use a zero (
00.00
) hold time if you just want to
move to the next segment.
6. Drying ware can take several hours, while holds at
peak temperature usually range 10–15 minutes to even
out the kiln. Feel free to experiment - there is no one
right way to program a kiln.
13.2.8 REPEAT STEPS FOR EACH SEGMENT
1. For segment two, the display will read
rA2
,
oF2
and
HLd2
2. For segment three, the display will read
rA3
,
oF3
and
HLd3
etc.
13.2.9 SET A DELAY (OPTIONAL - CAN BE SKIPPED)
1. If you want to set a delay, you can do it when the
display says
FIrE
.
2. You can add a delay time to the program by pressing
the
DOWN
arrow when you see
FIrE
but before you
press
ENTER
.
3. After you press the
DELAY
button you will see
dELA
flashing with a time value, typically
00.00
which
