Setting operation mode
Operating the device in mode A, b or d
Mode A
All settings will be stored if the device is switched off or disconnec-
ted from the power supply. The agitation and heating functions
will be set to OFF when the device is powered on.
Mode b
All settings will be stored if the device is switched off or disconnec-
ted from the power supply. The agitation and heating functions
will be set to ON or OFF when the device is powered on, depen-
ding on the previous status of the device.
Mode d
In Mode d the device behaves the same as in Mode A with the
exception that:
- The temperature setting must be confirmed by pressing the
temperature knob. To change the temperature setting, turn the
temperature knob until the desired value appears.
- The new value flashes for 5 seconds on the display. Confirm the new
temperature setting by pressing the temperature knob, otherwise
the temperature setting value will skip back to its previous value.

Er5
Providing safety protection, Er5 is taken to recognise that the
sensor has not been placed in the medium when the heating is
switched on.
Note: The user can set a value from 1 to 30 min for this time limit
depending on the application.
If time limit is set to 0 min, the Er5 detection is disabled.
This function will only be active if:
- Sensor temperature is < 50 °C
- Difference target temperature / sensor temperature > 5 K
Factory setting: 5 min
The time selected will be shown on the display when the device is
started up if the sensor is connected.
