Calibration Procedure 3:
for Rev. 6.x Board, Software Rev. 4.xx and 5.xx
This calibration procedure is for STAT
IM 2000/5000 non S units (2005-2007) with revision 6.x
controller boards and revision 4.xx or 5.xx software.
Important:
•
Incorrect or inaccurate calibration may cause unsuccessful sterilization of instruments.
•
Always calibrate the thermocouples after a thermocouple replacement, thermocouple bend
or disconnect, controller board replacement or microprocessor / eePRoM replacement,
steam generator replacement or probe bracket replacement.
•
Make sure that there is sufficient steam-process distilled water in the unit prior to starting
calibration.
•
Do not place the digital reference thermometer in direct sunlight, on the armature or on any
other hot surfaces. This may cause improper values on the temperature readout.
•
There are specific error messages (cycle faults) for these board types. These can be found
in the
Troubleshooting Cycle Faults
section.

•
Neither boiler requires calibration as these units are fitted with a separate validation
thermocouple.
•
This calibration procedure may also be used on earlier revision 2.x and 5.x controller
boards that have been upgraded to AleX steam generator (R5.xx software).
Calibration Procedure
Calibration of these boards should be done in the following order:
1. Reference voltage verification / adjustment
2. Chamber thermocouple calibration
3. Validation thermocouple calibration (automatic)
Required equipment:
• Control box - 01-103141S
• Digital voltmeter
• Calibration cassette (appropriate to model)
• Potentiometer trimmer
• Calibration jumper
• Digital thermometer
Setting up the unit for calibration:
1. Before starting calibration, turn the STAT
IM OFF and remove the cover.
2. Check that there is sufficient steam process distilled water in the reservoir, and that the
calibration cassette (6) is correctly engaged in the STAT
IM.
3. Install the thermocouple (7) into the cassette and attach the digital thermometer (8).
4. Ensure that the thermocouple and digital thermometer have matched serial numbers.
5. Install the calibration jumper (11) to Controller Board pins marked W1 (10).
