The Hold Temperature of the incremented/decremented step is the defined Hold Temperature plus the
summation of the increments/decrements. The first cycle is never incremented/decremented, only
subsequent cycles. If you select a decrement, the Hold Temperature is prevented from falling below 4°C.
If you select an increment, the Hold Temperature is prevented from rising above 99°C.
Similarly, under normal circumstances, the Hold Time of all steps is constant. However, it is possible to
automatically increment or decrement the duration of a specified step of a program.
Temperature profile of incremented Hold Time at step 3 of each cycle
The Hold Time of the incremented/decremented step is the defined Hold Time plus the summation of the
increments/decrements. The first cycle is never incremented/decremented, only subsequent cycles. If you
select a decrement, the Hold Time is prevented from falling below one second.
