1154 Conditioning Stage
The Conditioning stage is partitioned into two sequences: RH ramp‑up and RH hold
•
RH ramp‑up
is responsible for increasing the relative humidity (RH) in the sterilization chamber to the target RH
•
RH hold
is responsible for maintaining the programmed RH level for the specified amount of time to ensure the load has sufficient time to absorb water vapor
•
Relative Humidity (RH)
is the target %RH for the Conditioning stage
Special product loads or special cycles may require a very low %RH Select
No %RH Injection
to create a custom cycle where no vaporized distilled water is injected during the
Conditioning stage
•
Timeout
is the maximum time allowed for the chamber to reach target %RH during RH ramp‑up
•
Hold time
is the duration of time to maintain chamber target %RH (RH hold sequence) before exiting the Conditioning stage
•
RH injection rate
is the time period to allow water vapor to absorb before calculating the next RH injection duration There are three set points: fast, medium, and slow The Fast set point
is the preprogrammed setting Medium and Slow set points may be used depending on the absorption characteristics of the load Studies on each load type may be required to optimize the
RH injection rate parameter
•
RH lower limit
is the tolerance on the lowest allowable %RH during RH hold If the %RH falls below the programmed tolerance during RH hold, the GSX Series sterilizer will automatically
cancel the cycle
•
RH upper limit
is the tolerance on the maximum allowable %RH during RH hold If the %RH rises above the programmed tolerance during RH hold, the GSX Series sterilizer will
automatically cancel the cycle
