b. The temperature will increase at the ramp rate selected in Step 5 until the
user presses “Stop” or until the oven reaches a maximum temperature of
400°C, whichever comes first.
i. If the oven reaches 400°C during the ramping phase, “Ramping
Stopped” will be displayed and the unit will maintain the maximum
temperature for 30 minutes. After 30 minutes, it will revert back to the set
temperature to prevent overheating.
ii. If the “Stop” button is pressed during the ramping phase, the unit will
revert back to the set temperature.
9. Determine the Melting Point of the Sample:
a. Observe the following changes during the ramping phase:
i. Signs of change - Darkening, shriveling, sintering
ii. First signs of liquid formation
iii. Formation of a meniscus
iv. Formation of a completely clear liquid
b. Press “Select” to record the first temperature in the melting range. The oven
will continue heating.
c. Press “Select to record the second temperature in the melting range. The
oven will continue heating.
d. Press “Select” to record the third temperature in the melting range. The oven
will continue heating.
e. Press “Select” to record the forth and final temperature in the melting range.
Ramping will stop and the oven temperature will immediately start decreasing
back to the set temperature selected in Step 4.
10. View Recorded Data:
a. After the final temperature is recorded, “View Data?” will be shown on the
display.
b. To move on to the next prompt without viewing the data, press “Stop.”
c. To view the data for the test that was just completed, press “Select” and use
the Up and Down Arrows to scroll. When viewing is complete, press “Stop” to
move on to the next prompt.
11. Save Data to Unit:
a. After “Stop” is pressed, “Save Data to Unit?” will be shown on the display.
b. To move on to the next prompt without saving data to the unit, press “Stop.”
c. To save the data for the test that was just completed, press “Select.” When
saving is complete, display will move on to next prompt.
12. Save Data to USB:
a. After data is saved to the unit or “Stop” is pressed, “Save Data to USB?” will
be shown on the display.
b. To return to the set temperature screen without saving data to a USB, press
“Stop.”
c. To save the data for the test that was just completed to a USB, insert USB on
the right side of the unit and press “Select.” When saving is complete, display
will return to the set temperature screen.
13. Repeat Steps 4c-12 to continue testing with the same set temperature and
ramp rate selected in Steps 4 and 5.
14. If a new set temperature or ramp rate is required, use the numeric buttons
or Up and Down Arrows to select a new temperature. Repeat Steps 4c-12
to continue testing with the new set temperature and/or ramp rate.
15. If a new set temperature or ramp rate is required, or if testing is complete,
Press “Stop” after Step 12 to turn the heater off and return to standby mode.
16. Unplug unit when it is not in use.
