5. Confirm that the display appears similar to the example above.
The value in the lower right-hand corner (
DDD
) is the
difference
between the Chamber
and Validation thermocouple readings. The value in the upper right corner is the
Chamber
Temperature
(
TTT
). The value in the upper left-hand corner (
VVV
) is the
Validation
Thermocouple temperature. The 2 digits in the upper left-hand corner (
CVO
)
represent the offset between
Chamber
thermocouple and
Validation
Thermocouple
Offset
in hexadecimal. The 2 digits in the upper right-hand corner (
TO
) are the
Chamber
Temperature Offset
value in hexadecimal.
CHAMBER CALIBRATION:
6. Press the Unwrapped cycle button (first from the left) and after that press START
button to activate a chamber thermocouple calibration cycle. The system will run a
normal sterilization cycle. However, the LCD will continue to show the calibration
display as shown above. (Note: No “
∗
” will appear in this mode as it does for the
Validation Thermocouple calibration).
7. Wait for the chamber to reach the sterilization temperature of 134
°
C.
New!
Keypad functions at this time:
Unwrapped Key:
increment current selected offset
Wrapped Key:
decrement current selected offset
Stop Key:
end chamber thermocouple calibration
8. Observe the chamber temperature as displayed on the reference thermometer and on
the upper right of the Statim LCD (TTT value).
New!
Adjust the TO value by using
the Unwrapped and Wrapped keys until the displayed temperatures match to within
+/- 0.2
°
C. Please note that Chamber Temperature Offset TO flashes when it is
allowed to be adjusted.
9. When the adjustment is complete, press the STOP button to end the chamber
thermocouple calibration cycle.
10. Move to the Validation Thermocouple calibration procedure.
