Click the stirring control knob to visualize the set value. Turn the knob to set the new value and click to confirm.
To esc setting mode wait 10 seconds without touching any knob or push both knobs at the same time.
* The temperature control function of the heating plate can also be used as a safety thermostat. In this case the maximum temperature of
the heating plate will not exceed the full scale temperature set on the AREX-6 Digital/Digital PRO meaning that a longer heating time is
required in order to reach the temperature set with VTF or external probe inserted, but reducing temperature oscillation at set point value.
