Regulating procedure

To prevent the temperature from overshooting when a quantity of fluid is heated, a FUZZY
logic is used for the EKT Hei-Con in order to optimize the control. The heating function of
the magnetic stirrer is already switched off before reaching the reference temperature so
that heating is only effected by the residual heat from the hotplate.
Note
For heating small quantities (<500 ml): Set the temperature of the
hotplate to about twice the value of the reference temperature.
The maximum temperature should only be used for large quantities.
For reference values over 150 °C a slight control deviation can occur. This can be
compensated for by setting a higher reference value.
Press briefly
Press briefly
Press continuously
Press.
With the "Max" key, the security shutdown temperature is displayed.
In the bottom line of the
display the set reference
value is indicated. You can
now alter this.
Set the required reference
value using the arrow
buttons.
Fast run-through: after
3 seconds the reference
value is changed in steps
of 10.
The reference value is
taken over. After 3 secs
this is also carried out
automatically.
