STAT
IM 5000 Calibration
NOTE: Calibration Procedure 1: for Rev 3.x or 4.x Boards applies ONLY to STATim 2000 non S units.
Calibration Procedure 2:
for Rev 2.x or 5.x Boards, Software R1.xx or R2.xx
This calibration procedure is for STAT
IM
2000/5000 non S units (1995-2005) with revision 2.x or
5.x controller boards and revision 1.xx or 2.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/software types, which can
be found in the
Troubleshooting Cycle Faults
section.
•
In calibration mode, no error messages are displayed.
Calibration Procedure
Calibration of these boards should be done in the following order:
1. Reference voltage verification / adjustment
2. Steam generator thermocouple calibration (automatic)
3. Chamber thermocouple calibration
4. Steam generator re-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:
• Before starting calibration, turn the STAT
IM OFF and remove the cover.
• 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.
• Install the thermocouple (7) into the cassette and attach the digital thermometer (8).
• Ensure that the thermocouple and digital thermometer have matched serial numbers.
• Install the calibration jumper (11) to controller board pins marked W1 (10).
