Hi Igni,
Used this command below.
You can will change the path to where your hdf file is located.
Call DataFileLoad("C:\Users\pes5520\Downloads\REC285\REC285.hdf","HEAD_Data_Format","Load")
Note: which Dataplugin is used, on My machine, it also has others that will work on the HDF file that is a completely different format than the Head Acoustic File. There was also a "Head Data Format -Scaling" listed, this one kind of worked for your file, but the data values were all zero.
Please look at the image attachment. It shows the options for which dataplugin that I used.
Also attached a Tdms file for the output in the data portal after loaded.
