I just bought this tool and I'm very impressed, the only problem is the software. V3.32 wont let me name the files and build a data base. Version 5 (I think its called that) is great for building a database but in the graphing mode it wont zoom in like the other one does, I'm not sure if this is a glitch with me or what. I'm sure it zooms a bit if you have 24hrs worth but I think you need to get pretty close like the version 3.32 does. I'm sure someone figured something out, how do I name the files and save them to my computer on Version 3.32, if I can do that I'll be more than satisfied with this product. Any help here would be great, THX Matt

In the 3.32 software, once you have selected a file, if you click on "Setting", then "User Set" you can rename the file information. 

In the 5.2 software there is an issue with the label "zoom". This is currently being edited. What the engineers intended to convey was a "scroll" feature. Unless you have recorded enough data to fill the entire graph from left to right, the "zoom" or "scroll" will not be applicable.
