The two I am considering are : Watt's Up http://www.rc-electronics-usa.com/ammeters/dc-amp-meter.html eLogger V3 http://www.eagletreesystems.com/MicroPower/micro.htm I believe the eLogger V3 offers more features and has the potential of doing what I am trying to accomplish. Two emails to Eagle Tree have currently yielded no response to my questions. What I would like to do is capture data over a two week period, to be reviewed after the test. Since the turbine will be located in a remote location (i.e. no power for a laptop), I can't use the eLogger's "USB Live Mode" for real-time data capture and storage in the normal sense. What I can do, however, is build a simple and inexpensive PIC-based micro controller data recorder and capture the real-time data stream (via USB) at a rate I desire and store it on a flash device for later retrieval. Two questions: 1. Does anyone have experience or knowledge of the eLogger V3? 2. Has anyone captured the real-time USB Live Mode data stream and understand its data format?
