Chapter 12: Qualification Reports
ValProbe RT User Manual 133
Users can return to and select different templates for different groups (i.e., Distribution,
Penetration, or different chambers in one study).
Pass / Fail Criteria Calculations
A User can select up to 16 commonly utilized and regulatory driven criteria to customize their
reports based on their specific needs. The following definitions help clarify how these criteria
are utilized and applied:
Note: Only values that are outside the defined criteria are considered “Failed”. All values that
are equal to or within the defined criteria defined criteria are considered as “Pass”.
Each Group included in the Pass/Fail Criteria Report shall have a separate analysis
and report based on each group of sensors.
Process Temp Band: Using the defined process temperature as a basis, the criterion
describes an allowable temperature band above and below the process temperature. The
criterion is defined as the number of degrees above or below the criteria. For example, if the
Process Temperature is 121°C and a max value of 2 and min value of –2 is entered, the
application checks whether all the sensor values are within 123 (121 + 2) and 119 (121 - 2).
The criterion only “Passes” if all sensor readings are equal to or within the range of 119°C to
123°C.
Temperature Fluctuation (Max-Min) per Sensor: The Temperature Fluctuation (Max-Min)
per Sensor field defines the max fluctuation allowed for each sensor during the cycle. The
criterion “Passes” if all sensors (Max – Min) readings are equal to or less than the defined
criteria.
Temperature at / above Process Temp per Sensor: The Time at/above Process
Temperature per Sensor calculates for each sensor the total time for each sensor equal to or
above the process temperature during the cycle. The criteria fields allow the definition of the
maximum time, the minimum time or both. To meet the minimum criteria all sensor calculated
times must be equal to or above the minimum criteria. To meet the maximum criteria all
sensor calculated times must be equal to or below the maximum criteria. If both maximum and
minimum are specified, then all sensor calculated time must be equal to or within the defined
range.
Temperature at / Below Process Temp per Sensor: The Time at/below Process
Temperature per Sensor calculates for each sensor the total time for each sensor at or below
the process temperature during the cycle. The criteria fields allow the definition of the
maximum time, the minimum time or both. To meet the minimum criteria all sensor calculated
times must be equal to or above the minimum criteria. To meet the maximum criteria all
sensor calculated times must be equal to or below the maximum criteria. If both maximum and
minimum are specified, then all sensor calculated times must be equal to or within the defined
range.
Group Max-Min (spread) per Timestamp: The Grp. Max-Min (spread)/ Timestamp calculates
the Group maximum-minimum value for each timestamp. The criteria defines the maximum
allowable spread for all timestamps during a cycle. The criterion “Passes” if all Group Max-Min
temperature timestamps are equal to or less than the defined criteria.
