Heating and cooling times for steps (1), (3), (5) and (7) are set to 0 min. (full power).
Heating time for step (9) is set beyond capacity.
【Example operation with wait function “ON”】
When the wait function is set to ON, the system “waits”, without counting down time, until chamber
temperature (reading) is within the deviation zone of between -3°C and +6°C of the temperature setting.
When time is set to 0 minutes, the system will build heat at full power to reach setting as quickly as possible.
When time is set longer than system normally takes to heat or cool to selected temperature, unit will
automatically control heating and cooling so that temperature setting is reached (staying within the deviation
range) at the time setting.
If chamber temperature drops during temperature stabilization, such as when opening chamber door,
system will “wait” and pause countdown time if deviation zone’s upper or lower limit is exceeded.
【Example operation with wait function “OFF”】
When wait function is set to OFF, the system proceeds to next step when time setting is reached regardless
of whether temperature setting is reached or whether chamber temperature falls below or exceeds the
deviation zone.
When time is set beyond unit capacity to heat or cool (e.g. too short), unit proceeds to next step before
temperature setting is reached. Wait function should be set to ON for short ramp (build) times.
