5.1 Starting display
The display always appears when switching on the
device.
If the temperature is above 35 °C, the fan will start
automatically.
If the temperature is below 30 °C, the fan will switch off.
If one of the arrow-keys is pressed, you continue with
5.2 Selection of the target temperature.
5.2 Selection of the
target temperature
Adjustment takes place in steps of 1 °C.
The menu can only be left by turning the device off and
on or by time-out.
After 5 min (without pressing any key) time-out
appears and the device will be restarted
(see 5.1 Starting display).
When choosing a temperature, the fan will always be
switched off.
If a starting temperature higher than the current oven
temperature is selected, inserting the capillary tube will
start the normal process of melting point analysis.
If the starting temperature is lower than the current oven
temperature, an error message will be displayed for 3 s
when the capillary tube is inserted.

After that, the device will return to the starting display
and the procedure will be cancelled. The fan will be
started according to the logic.
The latest selection of temperature can only be erased
when turning off the device.
6. Starting the melting point analysis
6.1 In principle The starting of a melting point analysis will only be
effected by inserting a filled capillary tube in the oven, if
a starting temperature has previously been selected and
reached.
In the case of an unfilled capillary tube, an error warn-
ing will be displayed. It will be automatically deleted
after the empty capillary tube has been removed.
After inserting, measurement will automatically start.
When the capillary tube is inserted, the starting menu is
automatically shown.
If there is already a capillary tube in the oven before the
starting temperature has been selected, a message on
the display will ask you to remove the capillary tube.
Only then (automatically after removing the capillary
tube) the selecting menu will be shown.
The last selected starting-temperature remains in
memory until the device is turned off.
