2000 Calibration
Calibration Procedure 1: for Rev 3.x or 4.x Boards
This calibration procedure is for STAT
IM
2000 non S units (1992-1995) with revision 3.x or 4.x
controller boards
Important:
t Incorrect or inaccurate calibration may cause unsuccessful sterilization of instruments.
t 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.
t Make sure that there is sufficient steam-process distilled water in the unit prior to starting
calibration.
t 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.
t There are specific error messages (cycle faults) for Rev 3.x and Rev 4.x board types. These
can be found in the
Troubleshooting Cycle Faults
section.
t Typically, these boards were manufactured with four potentiometers (VREF, DISP, TC-CHM
and TC-BLR) and do not have a printer connector.
Calibration Procedure
Calibration of these boards should be done in the following order:
1. Reference voltage verification / adjustment
2. Steam generator thermocouple calibration
3. Chamber thermocouple calibration
4. Steam generator re-calibration
Required equipment:
t Control box - 01-103141S
t Digital voltmeter
t Calibration cassette (appropriate to model)
t Potentiometer trimmer
t Digital thermometer
Setting up the unit for calibration:
t Before starting calibration, turn the STAT
IM
OFF and remove the cover.
t 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
.
t Install the thermocouple (7) into the cassette and attach the digital thermometer (8).
t Ensure that the thermocouple and digital thermometer have matched serial numbers.
