8.2.19 Heat Step – sterile temperature overshoot control
This parameter is used to reduce overshoot of the sterilization
temperature by controlling the sterilization pressure. The
sterilization pressure is calculated by the unit based upon the
SteTemp parameter. When the cycle starts the heating rate in
the chamber is constant until the pressure in the chamber
reaches the sterilization pressure minus the
Heat Step. From
this point on heating is performed in pulses. Each pulse lasts
15 seconds and increases the pressure in the chamber by a
small amount until the proper sterilization pressure is reached.

8.2.20 PresInPsig – selects the pressure display units.
This parameter sets the units of pressure that are printed by the
printer and used on the digital display during St.By (Stand By)
and while running a cycle. The two choices are psia (absolute
pressure) or psig / InHg (gauge pressure and inches of
mercury) Changing this parameter does not effect the units of
calibration used in any other parameter.
