6.4.2. Example of a firing program to illustrate the firing segment
Example of a simple firing program to illustrate the firing segments and their values:

Visualisation of the example:
Firing program (firing curve)
Firing program sequence:
 The temperature rises at the entered, ascending ramp (heating up) [ramp rate] until the kiln reaches the soak or
target temperature.
 It then soaks (dwells) at the soak temperature for the soak period.
 It then runs the next segment until the end of the program is reached.
 It is possible to control ascending ramps (heating up) & descending ramps (cooling down).
 Ascending ramps (heating up) and descending ramps (cooling down) are referred to as the "ramp rate".
 The ramp rate is set in values between 1 and 999°C/h or as "FULL" (full load heating) or "END" (end of the
program).
 The soak/target temperature is settable over the range 0 to 1320°C (2408°F).
 The soak period is settable over the range 00:00 (no soak) to 99 hours 59 mins.
Note:
During soaking, the kiln temperature and the remaining soak time appear on the display at intervals of 15 seconds.
Description of the values
Program delay = 1 h (60 min)
 The firing program starts with a delay.
(Factory-set to 00 hours 00 min.)
Heating at 250°C/h
Heating up to 500°C
Hold for 0 min
Heating at 0°C/h
Hold at 500°C
Hold for 60 min
Cooling at 125°C/h
Cool to 20°C
Hold for 0 min
Setting the value to "END" ends the firing program.
