Voltage Data Logger January 03, 2015, 03:33:26 pm Yahoo Message Number: 150192If you are interested in things electrical in your LD, you may find this gadget kind of cool. http://www.lascarelectronics.com/temperaturedatalogger.php?datalogger=153Basically it is a recording voltmeter, that measures voltage on a schedule that you set. it will record up to 32000+ readings and provide a graph of its measurements. Rather cool if you want to know if your 4-stage power converter is actually cycling on its advertised schedule. Download the data using a USB port on your computer. About $66 from Amazon. Unfortunately the software only runs on Windows, but Windows on your Mac works just fine. The company also makes quite a variety of other loggers for temperature, humidity, CO etc.-Dave '06 MB, Indianapolis
