8.2.13 limitP add
–
defines the upper limit of the pressure in the
jacket
This parameter is designed as a safety measure that defines the
maximum pressure in the jacket during heating and sterilization
stages. The maximum working pressure in he jacket is defined
as the pressure that correlates to the sterilization temperature
+ 5.4°F. Parameter
limitP add allows to increase the pressure
above the maximum working pressure and defines the value of
this pressure.
Caution:
Setting this parameter to 4 psi may cause the Pressure Switch
and / or the Safety Valve to be activated.”
Example:
If the sterilization temperature is 273°F, the maximum pressure
will be 34 psig that correlates to 278.4°F (273°F + 5.4°F). If
limitP add is 2 the maximum allowable pressure will be 36. If
the pressure reaches the upper limit as defined by limitP add
(i.e. 36 in our example) the heating element will be switched off
and the pressure will begin to decrease. When the pressure
decreases below the maximum allowable pressure, the heating
element will be switched on again.

8.2.14 Calib Code – Calibration Code 107
This parameter is used to set the calibration code. The correct
code is needed to calibrate the autoclave. After calibration the
code should be set back to the default value (100) to prevent any
unqualified person from altering the calibration
