APPENDIX A STANDARD CALIBRATION
This is a two-point adjustment (100°C and 160°C). The dryer unit now heats to the second
temperature (160°C). Adjustment of the temperature is defined by two points. Proceed exactly as you
did for the first temperature. After you have set the display to agree with the thermometer, then press
the Enter button.
CAUTION: Danger of burns.
Be careful when removing the temperature calibration unit from the dryer unit as it can be
very hot. Allow it to cool down by opening the cover before removing.
Remove the calibration unit. Replace the pan support in its proper positions.
