After the channels are chosen, a screen is shown with a preview of all activated channels. The recording does not start automatically. To record data, The Record button must be pressed. This method supports the check of all signals before the recording is started. If a filename is chosen which exists already, you can choose between replacing the old file or append to the old file. Appending is only possible if the old and the new file have the same number of channels and the same sample frequency.
If a file is replaced, the old files will be renamed to *.bi! and *.tr! so that accidentially deleted files can be renamed again. Press Record to start recording. Press Record once more to stop recording but to stay in record mode. This can be useful if the recording must be paused and will be continued later. Pressing Stop leaves the record mode. However, it is possible to restart the measurement and append new data to the old file.
Hold Screen does not stop the data recording but only stops the plot of the signals. Press Channel Info to view the information about every channel which is recorded. The uppermost entry belongs to the uppermost plot.
