Residual Heat Warning (Hot) - Lbx Instruments H20D+ Mode D'emploi

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.

6.1.2 Residual heat warning (HOT)

In order to prevent the risk of burns from a hotplate, the digital hotplate has a residual heat warning function. When the
heating function is switched off and the heating plate temperature is still above 50°C, "Hot" will flash on the screen to
warn that there is a risk of burns from the hotplate. When the hotplate temperature drops to below 50°C, the system will
be automatically switched off. If users want to turn off the LCD screen immediately, just pull out the plug directly. Once the
plug is pulled out, the residual heat warning function will stop running.
6.2 H20 series
The function "heating" is switched ON or OFF by rotating the knob.
While the heating function is ON, the LED Heat is lit.
7. Stirring
H20D+ series: The stirring function is switched ON/OFF by rotating the stirring knob. The speed is adjusted with the knob,
too. When both the heating and the stirring functions are on, the LCD will display the set speed value for 5 seconds and
then shift to the real temperature value.
H20 and S20 series: The stirring function is switched ON/OFF by rotating stirring knob. The stirring speed is adjusted with
the "Stir" knob.
