11.For software revisions higher than 4.15 (R415) when chamber pressure is higher
than 115kPa the PO field will switch to indicate the POS – Pressure Offset
Sterilization. During the sterilization phase, after adjusting the temperature, press
R&P key to select the PO field (PO field will be flashing) and using the keypad, adjust
the pressure offset POS to match the external meter pressure indication within 1 kPa.
NOTE
: POS should not be more than 14 counts (7kPa) away in any direction from
POA.
TIP:
To make sure the calibration has been done correctly, look at the external
meter. When it shows 136.5°C you should hear the valve clicking (the valve opens at
136.5°C).
12. Verify that for the rest of the calibration cycle the temperature and pressure
readings (internal and external) are the same.
13. When the adjustment is complete, press the STOP button to end the chamber
calibration cycle. Calibration cycle will end automatically after 5 min of holding the
temperature above 134
°
C. Press the Stop button again to reset the unit.
NOTE
:
for software revisions higher than 4.15 (R415): If during recalibration POA
is changed, the value of POS will be automatically reset to the new value of POA,
therefore when chamber pressure is higher than 115kPa, POS has to be readjusted.
14. Power off the Statim.
Calibration of the Statim S-Class autoclave is now complete.
