Controlling Solution Temperature Using External Probe
To control the solution temperature plug a PT100 probe into the probe receptacle located on the back side of the unit.
Place the probe into the solution. The display will indicate the actual temperature of the solution as measured by the
probe.
The external probe offers more exact temperature control than regulating the top plate by the internal sensor. If you
need to maintain a precise setpoint it is recommend to use a probe to control the solution temperature instead of
controlling by the top plate temperature.
When using a probe with the SUPER-NUOVA
+
unit it is recommended that a clamp on a support rod be used to hold
the probe in the solution.
To ensure accurate probe readings, as much of the probe sheath as possible should be immersed in the solution. Make
sure the probe is immersed in the liquid and is not located in air or outside of the solution. If the probe is plugged into
the hot plate, but is not in solution while the heat control is operating, the temperature display will continue to indicate
an ambient temperature, and a probe out of solution error will occur. Because the set point cannot be reached the
heating element will continue to supply heat to the top plate, and the maximum top plate temperature(300°C, 400°C or
450°C) may be reached. If the remote probe does not sense a temperature change in three minutes the unit will display
ExProbe Err and shut down.
Using Preset Programs
The SUPER-NUOVA
+
unit features the option of presetting 3 setpoints into its memory. To program a preset, press any
preset button, and the indicator LED on the number button will be illuminated. Then adjust the time, speed and heat
features to your desired setpoints. Press the number button again to exit the preset program. The setpoints are stored
in memory automatically. The presets will be held in memory, even if the unit is unplugged, until you choose to override
it with another preset.
To activate one of the presets, press the corresponding number then press the knob, the time, speed and heat features
will automatically adjust itself.
It may be helpful to set one of the presets at “OFF.” This way, the heating can be shut off quickly.
The SUPER-NUOVA
+
unit has a Preset Continue function. It means different presets can run continuously when Preset
Continue is being utilized. The default setting is to turn off the function. By pressing 1 and then pressing the knob
the unit will run by continuous presets by order 1, 2, 3. By selecting 2 and then pressing the knob the unit will run by
continuous presets by order 2, 3.
See “System Configuration” section of the manual to activate the Preset Continue function.
