3.4. Control
Behaviour
To prevent as much as possible, any overshooting of the temperature when heating a
quantity of liquid, the EKT 3001 uses FUZZY logic for control optimization. The magnetic
stirrer’s heating is switched off before the desired temperature is reached so that the liquid
is then heated only with the residual heat in the hotplate.
To heat small quantities (
<
500 ml): Set the temperature of the heating
plate to approx. double the value of the desired temperature. The maxi-
mum temperature is to be used for large quantities only.
Desired values of over 150°C may be accompanied by a slight control deviation. This can
be compensated by setting a higher desired value.
