Warning!
Do not remove the vessel from the heating plate when the instrument is working.
Heating function
The device is controlled by digital temperature control technology which has two separate safety
circuits. The heating plate is kept at a constant temperature by a digital control circuit. For a precise
display and control of temperature inside the medium, please use the external temperature sensor
PT 1000.
•
Plug in the external PT 1000.
•
Set the temperature by turning the temperature control knob slowly to the target value.
•
When the heating function is switched on, the LED displays the temperature value on the left-
hand side.
•
The heating function is switched on or off by pushing the heating knob.
When turned on, the instrument automatically displays the last running speed and temperature para-
meters. Generally, the LED screen cannot display the actual temperature of the sample in the vessel
or of the surface of the heating plate. The temperature differences are as following:
•
Heating plate center and outer edge.
•
The sample in the vessel and the surface of the heating plate.
In order to ensure the accuracy of the temperature inside the container, please use the external
temperature sensor PT1000.
Using an external temperature sensor PT 1000
When the PT 1000 sensor is connected and the temperature control knob is rotated, the LED displays
the temperature setting value and shifts to real value in 5 seconds. Compared with the temperature
control of the heating plate, the external temperature sensor can control the medium’s temperature
more precisely. The heating function will be stopped automatically under abnormal conditions.
Please operate following the instructions below:
•
Switch OFF the instrument.
•
Ensure the external temperature sensor is inserted into the heated media.
•
Switch ON the instrument and run heating function.
If the heating function does not work, please contact your distributor.
