Preparing the Experiment

A succession of profiles predifined by the user:

what is a profile ?

one ramp caracterized by:

heating or cooling rate.

Field to be applied during the ramp.

the dwelling temperature to reach.

Field to be applied at this stage

Possibility to link as many profiles as needed.

Running the experiment

• A labview program runs automatically the profiles.txt file

• Every profile (one line in profiles.txt ) measurement is saved in one file.dat

• Possibility to modify the Profiles while the experiment is running by removing or adding line(s)
