F0 parameter settings can be modified in this sub menu. The mathematical expression used for the F0
calculation (in minutes) is as follows:
where T is the vessel temperature, z is a microrganism-related parameter ranging from 4,0 to 15,0
(default 10), ∆t is the time interval between measurements. The calculation of F0 starts after a threshold
temperature Ts, ranging from 100 to 120 °C (default 100 °C), is reached.
From the F0 menu, press ENTER.
