Confirm that the plateau and ramp
rate values are correct and press
the ‘START’ button as indicated. At
this point the machine will heat up
to the plateau temperature, the time
taken to reach this temperature will
be indicated by a count.
Once the plateau temperature is
stabilised a countdown from 120 to 0
will begin followed by an audible
bleep. When this screen is shown
press the ‘START RAMP’ button
indicated to proceed.
During this ramping phase you should
be observing your sample, through the
viewer, until it begins to melt. Pressing
the numbered buttons will record the
temperature at that point; each button
corresponds to one of the 3 sample
holders. Each button can record up to
7 values, with an audible bleep
following each successful recording.
To view the results recorded by
pressing the buttons in the previous
step, press the ‘VIEW RESULTS’
button indicated.
The results are shown on screen.
You can view more results by
pressing the ‘UP’ and ‘DOWN’
buttons, or view the results recorded
for the different tubes by pressing the
buttons numbered in the picture.
Once finished press the ‘DONE’
button indicated.
