If the MKT calculation is desired the value of Heat activation can be set.
Note: Changes to lethality calculations are permitted only if given permission inside
preferences. Changes to D-Value can be permitted inside policies.
Lethality and Time of Sterilization
New European regulation have placed and emphasis
on ensuring you have proper steam quality when
calculating lethality. For this reason, we have added
additional options which if checked will only calculated
the Instantaneous lethality for the time stamp if the
Saturation Pressure and Temperature are within
defined limits set in the Time of Sterilization
calculation.
The Time of Sterilization calculates the total time of sterilization by combining the Steam quality
criterion, along with the measured reference temperature. Time is counted if the measured reference
temperature is at or above the process temperature and the steam quality as defined by Temperature
minus calculated Saturation Temperature (T-Sat) is within the specified range.
