Programming
A firing segment
An ST215 firing segment comprises a ramp followed by a soak period. Two
segments can be used for simple firing (biscuit firing for example) or several
segments can be used per program for complex firing (crystal glazing or glass-
making for example).
The ST215 ramps the kiln temperature at the required ramp rate until the kiln
reaches the soak / target temperature. It then soaks (dwells) at the soak tem-
perature for the soak period. It then runs the next segment until the end of the
program is reached.
The ST215 is capable of both positive (heating) ramps and negative (cooling)
ramps - as used in glassmaking for annealing. The type of ramp is clearly
shown on the mimic display during firing.
The ramp rate is settable in the range 1°/hour to 999°/hour or FULL (full power)
or End (end of program).
The soak / target temperature is settable over the range 0 to 1400°C (2552°F).
The soak period is settable over the range 00.00 (no soak) to 99 hours 59
mins.
Note: during soaking the ST215 display alternates every 15 seconds
between kiln temperature and soak period remaining.
