Check and adjust chamber thermocouple calibration as appropriate to board type.
Note: on ‘S’ class units, pressure transducer calibration using the pressure reference meter must be
done during this phase. Software revision XXXXR4XX onwards requires this to be done at barometric
pressure at the start of the cycle. Previous software variants require this to be done during the
sterilization phase.
When set, and during the running cycle, check that the chamber temperature matches the reference meter
and that actual and theoretical pressure are within 1 kPa. This is important for the efficient balance of the
control and validation circuits. Failure to achieve this may result in unnecessary cycle failures.
Re-check steam generator thermocouple calibration as appropriate to board type.
t Note 1: steam generator calibration is not required for software revision numbers XXXXR4XX
onwards.
t Note 2: if the initial steam generator calibration offset and final steam generator caibration
offset are > 8 hexadecimal values apart, the steam generator MAY be compromised and further
investigation should be undertaken.
After completion of calibration, run a standard cycle to check temperature and pressure values.
Reinstall cover, and check all cycles are available.
Insert customer’s cassette and run standard cycle. Check for leaks.
For revision 7 units ONLY: Enter service mode and activate ‘Back up NVRAM’.
