for logging, you need to select the correct .ADS file (Tpro4002.ads) in the datastreams directory.
Then you click the double-arrow button at the top of the screen to begin logging.
Click the M (monitor) button to see log traces
Click the D (dash) button to see numerical values.
right click on a graph or numerical display to see the list of displayable data.
To save a log, you must first select a filename in the ALDL/Monitor menu. Then just click the "Red Dot" button and the laptop will save the logfile.
There is a lot of info in the help files, or post more questions.....
