1. Reference voltage verification / adjustment
To verify / adjust the reference voltage:
1. Turn the unit OFF.
2. Connect the Control Box (1) to the Controller Board (2).
3. Connect the digital voltmeter (4) to the Vref terminals on the control box.
4. Set the voltmeter to read DC Volts with a resolution of 1mV.
5. Power the unit ON.
6. Adjust the Vref potentiometer until Vref is 2.520 V ± 0.001.
7. Once Vref is adjusted, apply a drop of non-conducting lacquer or nail polish to the
adjustment screw of the potentiometer.
2. Steam generator thermocouple calibration
To calibrate the steam generator thermocouple:
1. Turn the unit OFF and install a calibration jumper on Controller Board header W1.
2. Turn the unit ON. The LCD should appear and be similar to the diagram below:
3. To start a steam generator (self-calibrating) cycle, press and hold the UNWRAPPED cycle
button on the control box and press the START button. An asterisk * will appear next to
the message ‘CALIBRATING’.
4. If the asterisk * does not appear, press the STOP button on the control box twice to reset
the unit. Turn the power switch OFF then ON again.
5. Hold down the UNWRAPPED cycle button on the control box and press the START button
to start the self-calibration again.
6. During the steam generator warm up (before the cassette temperature reaches 100°C),
check that the displayed chamber temperature matches the reading on the digital
thermometer to within 2°C.
7. If the value is greater than 2°C adjust the TC-ADJ potentiometer (9) so that they match.
8. As the cycle proceeds, the chamber temperature reaches the sterilization temperature,
drops to 115°C and then regains sterilization temperature.
9. After 20-40 seconds, a long beep will sound indicating that steam generator calibration is
complete.
10. The number in the upper left-hand corner of the LCD has changed to display the new
steam generator offset value.
