The heating function is switched on or off by pushing heating knob.
When setting the temperature, be aware that the display temperature and the actual temperature may have the following differences:
•
Hotplate center and outer edge.

Working with external temperature sensor
The external temperature sensor FagronLab™ PT1000 is the manufacture's standard accessory. If the sensor is plugged in,
"Probe" will be shown on the digital display to indicate that the sensor is operating. The value of external temperature sensor
and the actual temperature are displayed. Safe circuit controls hotplate temperature. Comparing with the temperature control
of the hotplate, the external temperature sensor can control the medium's temperature more precisely.
To plug in the sensor's holder you have to remove the plastic cover.
•
Turn off the device with power ON/OFF button.
•
Plug in the external sensor PT1000 and follow the previous steps.
Note:
•
Forbid to insert or remove the PT1000 sensor when device is switched ON!
Residual heat warning (HOT)
In order to prevent the risk of burns from the hotplate, digital hotplate has a residual heat warning function. When the
heating function is switched off and the hotplate temperature is still above 50°C, "Hot" will flash on the display to warn
that there is a hazard of burns from the hotplate. When the hotplate temperature drops to below 50°C, the unit will
automatically switch off. If users want to turn off the LCD immediately, just unplug the power cable. When the power cable
is pulled out, the residual heat warning function cannot be visual.
10. Stirring
The function "stirring" is switched on or off via pushing the stirring knob. The speed can be set by the knob (100 to 1500 rpm
in steps of 10 rpm). When both of functions heating and stirring are switched on , the LCD will shift to the speed value and
come back to the temperature value in about 5 seconds.
