What is F0 Functionality in Paperless Recorders?
In the realm of sterilization processes, the F0 value is a critical parameter that helps determine the effectiveness of heat treatment in achieving microbial lethality. The F0 value, expressed in minutes at a specific temperature, quantifies the exposure time required at a given temperature to ensure that a product is effectively sterilized. Paperless recorders equipped with F0 calculation capabilities provide an efficient means to monitor and document these processes accurately.
Calculating F0 with Paperless Recorders
Modern paperless chart recorders, such as those offered by Silver Automation Instruments, enable users to perform F0 calculations using various temperature inputs, including PT100, PT1000, RTD, and thermocouples (TC). The F0 calculation formula is defined as:
Where:
-
is the recording interval (converted to minutes),
-
represents the measured temperature,
-
and
are set temperature parameters adjustable within the recorder's configuration settings.
For effective operation, the F0 calculation process is set up as follows:
1. Channels 1 and 2 function as standard temperature input channels.
2. Channels 3 and 4 are designated for F0 calculations.
The F0 value resets to zero each time a recording session begins, regardless of the trigger method used. This ensures that calculations reflect the current batch or session accurately.
Operational Guidelines for F0 Calculation of Graphical recorder
To achieve precise F0 calculations in color paperless recorder, certain operational guidelines must be followed:
- The measurement range for channels 3 and 4 should be based on expected values. For instance, if the anticipated F0 value is around 60 minutes, setting the range to 0.0–100.0 is appropriate. The default factory setting is 0.0–200.0.
- The temperature threshold for F0 calculations can be customized. For example, setting the threshold at 100°C means that F0 calculations will commence only when temperatures exceed this point. If the temperature drops below this threshold, the F0 accumulation pauses, but does not reset to zero, allowing for continued monitoring upon temperature recovery.
- Manual reset options are also available. Users can attach a button to reset the current F0 accumulation without affecting the recorded data curve. If the temperature conditions permit, the calculations will resume from the last recorded value after the reset.
