8.6. Specifying Calculations
Figure 101: Calculations
With sensors defined and assigned to one or more groups, calculations must be specified for
all sensor groups during the qualification study. Calculations include, Statistical, Lethality,
Saturation pressure of steam, and Saturation temperature of steam calculations.
Statistical
The Statistical Calculations are automatically generated and include Min, Max, Max and Min
Sensor Label, Max-Min, Avg and Standard Deviation, Max–Avg, Avg-Min, and Cycle Time.
Lethality
Figure 102: Lethality Calculation
Lethality calculation is typically used for most types of sterilization and Depyrogenation ovens
etc. It calculates the number of equivalent minutes spent at the Base Temperature for each
sensor.
