How to generate an ltr-file?

Please read chapter 2 of your printed manual, run a measurement and make sure everything is adjusted well and the exposure time allows a quite good signal so that half of the interferometer charts is illuminated. Stop the measurement and start the recording by selecting "Operation | Start | Recording ..."

and choose a filename and location for the recording. Immediately after closing the dialog the recording will start and the measurements will be saved until you press "Stop". It is not necessary to produce very long recordings as the filesize is growing strongly with the measurement count. Usually up to 100 measurement points are more than enough.
