4.3.4. Operation of the Hot Plate/Stirrer without a Temperature Sensor
Note!
In contrast to operation without temperature sensor, the laboratory hot plate now
features:
Automatic temperature control instead of fixed heating temperature controlled by the
heating power.
When you press “Select” to see Pro.temp, it will display solution temperature.
1.Connecting the Temperature Sensor
Make sure that the hot plate / stirrer is completely switched off.
Be sure to use the correct temperature sensor
Connect the temperature sensor at the rear of the hot plate / stirrer
Make sure that the cable of the temperature sensor is routed so that it
cannot touch the heating zone.
Immerse the temperature sensor into the liquid min.30 mm in depth.
2.Switching the Hot Plate/Stirrer on
Please refer to 4.3.3.
3.Setting the temperature
e.g. The actual “TEMP” is 70°C
Refer to 4.3.3 for how to set the temperature, but please note the
following points
Now the instrument will enter the external temperature control
mode(to measure and control the temperature of the solution
accurately) The maximum set temperature is 300°C
Press the SELECT Button to select Pro Temp, and now the display
shows the solution actual temperature measured by the temperature
at that time.
