The device is controlled by a digital temperature control technology, which 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 from a separate, adjustable safe circuit. The two internal
temperature sensors (PT1000) for temperature control are built into the hotplate. The single
external PT1000 can monitor the temperature of the sample.
If using an external sensor PT1000: Always connect to the device BEFORE turning the power on
