above the room temperature recorded in
the previous step.
• Check that the ramp rate is 5C/sec and
change if necessary.

aware of how well the temperature feedback
is operating so you should get used to
monitoring the temperature data history:
• Live graph - Click on the ‘More’ button
once to display the graph. Click on the
‘More’ button multiple times to add
sensors to the data plotted.
• For more information on datalogging,
please see
Section 19.7 on page 217.
