CHAPTER 1 - GETTING STARTED
MB90 MB120 Series Service Manual
Press the Next and Start button to
initiate the temperature calibration
process. Follow the screen
prompts throughout the process.
The dryer unit is heated to a temperature of
100°C. You can observe the progress on the
display as the dryer temperature and count
down period are displayed. After 15 minutes,
read the thermometer through the inspection
window on the cover and enter this
temperature. Using the up/down arrow
buttons, adjust the display reading to agree
with the thermometer. Use the left/right arrow
buttons to highlight ACCEPT NEW CAL then
press the Enter button. You have 10 minutes
to make this adjustment, otherwise the
calibration is terminated.
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, highlight
ACCEPT NEW CAL, then press the Enter
button. The display returns to ANALYZER
SETUP.
