STATIM 7000 Service Manual – Calibration

7. VCAL value should be adjusted so that the VVV value is the same as the line voltage
measured by the reference voltmeter connected to the power line (same power outlet
where Statim power cord is plugged in). Calibration should be done within ±2%.
8. This calibration phase lasts at least 30 seconds and it ends either by pressing the
R&P button or automatically when the unit moves to the Conditioning phase. When
the Voltage Reading calibration phase ends the screen moves to the main calibration
screen, see below (see item 5 above for a description of this screen):
Note: No “
∗
” will appear in the Chamber thermocouple calibration screen as it does
for the Validation Thermocouple calibration
9. Wait for the chamber to reach the sterilization temperature of 134
°
C.
Keypad functions at this time:
Unwrapped Key:
increment current selected offset (flashing offset)
Wrapped Key:
decrement current selected offset (flashing offset)
Stop Key:
end chamber thermocouple calibration
10.Observe the chamber temperature as displayed on the reference thermometer and
on the upper right of the Statim LCD (TTT value). Adjust the CO value by using the
Unwrapped and Wrapped keys until the displayed temperatures match to within
±0.2
°
C. Please note that the Chamber Temperature Offset (CO) is flashing when it is
allowed to adjust it.
11.When the adjustment is complete, press the STOP button to end the chamber
thermocouple calibration cycle.
12. Move to the Validation Thermocouple calibration procedure.

13. Turn the machine off and back on, while keeping Unwrapped and Wrapped
button pressed to go back to
Service Mode
. Enter password to continue. Toggle
using keypad through the menu selection to reach Calibration option and press R&P
key. The display should show the calibration screen.
14. Check that there is sufficient water in the water reservoir before proceeding.
15. Start a Validation Thermocouple self-calibration cycle. To do this, press and
hold
the
UNWRAPPED button and in the same time press START button.
16.The calibration cycle will start by entering the heating up phase and the screen will
change for the
