Mode C
In this mode, the device can be used either with or without a
temperature sensor.
When the device is switched on using the main switch, the
stirring and heating functions are started in the last set status
and at the last set values. The set nominal values in operating
modes A and B cannot be modified.
Changing the operating mode
- Scroll down to the "Mode" icon in the menu
- Open the submenu by pressing the rotary knob (D)
- Use the rotary knob (D) to select the desired mode and
confirm by pressing the rotary knob (D)
- A short description of the operating mode is then shown
on the display
- Confirm selection of the operating mode by pressing the
rotary knob (D) once more.
Functions
Regulation of the temperature of the medium
using PT100 temperature sensor
When using the PT100, the selected temperature control mode is
shown on the digital display by the
The target temperature (2) and the
current temperature (5) shown on
the display refer to the temperature
of the medium. The heating plate
temperature is limited by the set
safety temperature (7). The medium
temperature is controlled by means
of a microcontroller. The medium
temperature is measured by the PT100
temperature sensor and is heated
up as quickly as possible without
overshooting to the set temperature.
The microcontroller is capable of
adjusting automatically to the different
heating capacities of various vessels
and their contents. As a result, the heat
is distributed in an optimum fashion
with no temperature drift or ripples.
Control methods
The user is able to set the device to three different methods
depending on their specific needs. The selected temperature
control method is displayed alongside the symbol (11).
Fast PID: combines the advantages of the PID and two-point
methods (very fast
heating and high
accuracy; possible
overheating).

T
Set
PID: For use with very sensitive materials which need to be
handled carefully.
Advantages:
• v ery accurate warming
of the liquid
• n o exceeding the target
temperature
Disadvantages:
• s low heating operating
Two-point:
For media which is not too sensitive.
Advantages:
• H eating much more
rapid than PID
Disadvantages:
• P ossible overheating of
up to 10 K
Changing between the
control methods
- Scroll down to the
"Heating" icon in the menu
- Open the control method
submenu by pressing the
rotary knob (D)
- Use the rotary knob (D) to
select the desired mode
and confirm by pressing
