I am measuring the Helium concentration inside a protective Mask relative to the concentration of the measuring cell (round 4%). To correctly calculate the fit factor of a mask the proband makes different head movements, such as nodding and shaking the head which is written down in the string.
While the setup works, there are a few things I have not figured out yet:
1) The string input keeps adding up ending in something like “String1\0AString2\0AString3\0AString4”. How can I tell Labview to not add the strings
2) I would like the vi. to ask for the path and filename not when the measurement starts, by activation of the Boolean switch named “Aufzeichnung”, but when the vi. is started
