Setting the Temperature
The SUPER-NUOVA
+
heating unit has an electronic
closed-loop feedback control which will accurately
maintain temperature setpoints from 30°C through
300°C, 400°C or 450°C(depending on the model). An
unloaded hot plate will heat to maximum temperature
in just 5 minutes. A “CAUTION HOT TOP” light on the
front panel will illuminate whenever the top surface
temperature exceeds 50°C. The temperature may be
controlled either at the top plate by the internal Type
K thermocouple sensor, or in the solution using an
accessory ungrounded PT100 probe. If a probe is used,
the display will indicate “R” after actual temperature.
The SUPER-NUOVA
+
heating units will accept any
ungrounded PT100(PT1000) probe, however the
accuracy of probes other than those tested and specified
may not reach the probe accuracy rating designated.
To set the temperature, press “TEMP” key located
under display. Then the temp setpoint will flash. Use the
knob on the front panel to select a temp. Turn the knob
clockwise to increase the temp or counterclockwise to
decrease the temp. When desired setpoint has been
reached, press the “TEMP” key or wait 10 seconds, the
temp setpoint will no longer flash indicating that it has
been set.
Note
Boiling times are dependent on solu-
tion volume and the surface area of the
flask that is exposed to the hot plate. For
example, when heating the same amount
of solution in a 2L flask vs. a 1L flask, the
solution will heat about 20% faster.
Note
The top plate temperature will be higher
than your solution temperature.
