Instructions for the Calibration of Statim 7000 Cassette Autoclave
®
Warning
Incorrect or inaccurate calibration may cause unsuccessful sterilization of
instruments.
Statim units contain electronic components that may be damaged or
destroyed by electro-static discharge (ESD). Observe appropriate
safeguards when calibrating.
Always wear a static strap when working with or near printed wiring
boards. In addition, use static foot-straps, grounding mats and grounded
work surfaces when calibrating.
Make sure that there is sufficient water in the unit prior to starting
calibration
. If a new SciCan Water Filter Cartridge is used select water
priming option in the Technician menu.
The chamber and validation thermocouples must be calibrated to ensure the correct
operation of the Statim Autoclave.
Always recalibrate the system thermocouples
following a software upgrade, when the steam generator is serviced, when the
P.C. board is replaced, or when either of the thermocouples is replaced. Pressure
value is calculated from the calibrated validation thermocouple reading, no
pressure calibration equipment is needed during the calibration procedure.
The steam generator thermocouple doesn't require calibration. However, the Chamber
and Validation thermocouples must be calibrated to ensure the correct operation of the
unit. Also the voltage and water conductivity readings must be calibrated. The voltage
reading calibration is part of this instruction whereas the conductivity calibration is part of
another calibration instruction.
Validation thermocouple calibration is done automatically by running a special calibration
cycle.
The chamber thermocouple is calibrated by adjusting the Chamber Thermocouple Offset
using the Unwrapped and Wrapped keys while comparing a temperature on the display
with a temperature measured by a reference thermometer.
To calibrate a Statim 7000 unit, follow these steps:
SETUP:
1. Turn the unit off and fill the reservoir with water.
2. There is no need to remove the cover from the Statim 7000 in order to perform the
calibration.
3. Install a calibration cassette with the reference thermocouple inserted into the hole in
the front of the chamber.
4. Power up unit while keeping Unwrapped and Wrapped button pressed to enter Statim
