Hit Set Ramp key once again to exit gradient setting.
Having set a non-plausible time value, you may not exit temperature
gradient setting mode with Set Ramp key. Display shows “time invalid”
and cursor marks non-plausible value that needs to be changed.
Time values from step 1 to step 9 need to be ascending.

10.5.2 Delete values
For deleting a cursor-marked time value, rotate "Value" button CCW until „---„ is
displayed. Adhering temperature value automatically is set to „0“.
10.5.3 Limiting temperatures
Within a temperature range of 20°C and 160°C, max. temperature rise / drop, in
absence of optional forced cooling, makes reference to the table below (for physical
reasons):
temperature range max. temperature rise
max.
temperature drop
20 – 80 °C 3°C / min 1°C / min
81 – 130 °C 2 °C / min 2°C / min
131 – max °C 1°C / min 3°C / min
Deviating temperature rise values cannot be achieved within the time interval
specified; the same of course is true for temperature drop.
10.6 Activate temperature gradient
Activate temperature gradient by hitting the Ramp active key. This mode is
confirmed by the Ramp active LED. A temperature gradient set as described in
progress time, i.e. time elapsed
