2 Concept of saving
The measurements are saved on the SD-card, which is plugged into the SD-slot of the measurement
device. The measurement device uses the sub directory „ZFG“ of the SD-card. There are three
different file types in it: .ZXZ-files, .NRZ-files and .ZXC-files.
Each measurement will be saved in an own ZXZ-file. The file name contains the test number (e.g.
10 measurements have been saved so that 10 .ZXZ-files are created in the folder
(0001.ZXZ...0010.ZXZ)).
The number of .ZXZ-files is saved in the ZFG.NRZ-file. The ZFG.ZXC file contains the card
number. The measurement device uses every file. When manual changes are made (i.e. renaming or
deleting of files) it is possible, that the measurement device does not recognize the „ZFG“ folder
anymore. In this case, when you try to view the card in measurement device, the following screen
appears:
To avoid problems, it is not recommended to manually change the „ZFG“ folder. To back up data,
save the whole folder „ZFG“. If data are not needed anymore, delete the complete folder.
2.1 Measuring without SD-card
It is possible to perform measurements without plugged in SD-card. In this case, the measurement
will not be saved. When starting a measurement without SD-card, following warning appears on
screen:
