Techne TC-3000G - Manual (Page 39)

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.

TO PROGRAM INCREMENT OR DECREMENT TEMPERATURE OR TIME
Under normal circumstances, the Hold Temperature of all steps is constant. However, it is possible to
automatically increment or decrement the temperature of a specified step of a programme.
