In addition to recipe-specific parameters, your fluxer provides extra versatility
through flexible parameters that will apply to all fusion programs.

In the global parameters page, you can change the instrument's interface
language by selecting your preferred language in the list.
Holding
temperature
offset
In order to keep the furnace up and ready for the next fusion, the instrument can
maintain power to the furnace to keep it hot. This will help skip the initial ramping
time, thus quickening fusions and increasing sample throughput.
In the global parameters screen, you will find a slider for "Holding temperature
offset". Indeed, the holding temperature will be calculated based on theStep 1
temperature, plus or minus the global parameter offset.
Example:
The offset can be positive or negative.
Using a positive offset, say +200ºC, will prepare the furnace to receive the room-
tempered platinumware holders at the beginning of the process. Indeed, a
temperature drop in that order of magnitude is typically observed when the door
opens and the linear motion system slides the platinumware holders into the
furnace.
On the other hand, using a negative offset will save energy and increase furnace
life.
Keep in mind that the holding temperature depends on the fusion program
currently loaded on the interface screen. Changing the fusion program could
therefore change the holding temperature (because all fusion programs do not
necessarily have the same temperature set at Step 1).
When the instrument is turned on, the furnace will automatically be activated to
reach the holding temperature.

Global parameters
To modify the global parameters, first unlock the advanced mode
(see page 37, Unlocking the advanced mode), then touch the Global
Parameters icon that is now available on the main display screen.
In your fusion program, you have set Step 1 with a temperature of 700ºC,
and the global parameter for holding temperature offset is +50ºC. Then, no
matter how the parameters for the rest of the program are set, once the
fusion is complete, the furnace will maintain a temperature of 700 + 50 =
750ºC.
