The heating function will stop automatically under abnormal conditions.
In that case, please follow the instructions below:
Switch OFF the instrument.
•
If using external temperature sensors, ensure they are connected and inserted into the media to
•
be heated.
Switch ON the instrument and run the heating function.
•
If the heating function did not work, please contact the manufacturer/supplier for technical support.
When the equipment is switched ON, it displays the speed and temperature parameters used on the
last use.
Generally, the LCD screen cannot show the real temperature of the medium in the vessel or on the
plate. Temperature differences exist in the following cases:
Hotplate center and outer edge.
•
The sample container and the container.
•
In order to ensure that the temperature inside the container is measured accurately, please use the
external temperature sensor PT1000.
The external temperature sensor PT1000 is the manufacture's standard accessory that, compared to
the temperature control of the hotplate, can measure the sample's temperature in a more precise
way.
If the external temperature sensor is needed, it must be plugged in before the device is
•
switched ON.
Ensure the external temperature sensors are firmly connected and submerged into the media
•
before heating (fig. 8).
If the sensor is plugged in, "Probe" will be displayed on the digital display to indicate that the
•
sensor is operating. The set value of external temperature sensors and the actual temperature
are also displayed.

Warning!
Plugging in / Pulling out external
