Heating
With the digital temperature control, the machine has two separate safe
circuits. The hotplate is kept at a constant temperature by a digital control
circuit. The hotplate temperature can also be monitored by another
adjustable safe circuit. The two temperature sensors (PT1000) internal
for temperature control are built into the hotplate.
•
Set temperature by the temperature setting knob.
•
Heating is switched on/off by pressing the temperature setting.
•
The set temperature of last operation will be displayed when the
machine is switched on. Normally, the set temperature and the
actual temperature may probably have some differences:
-
Hotplate center and outer edge
