This data logger measures and stores up to 32,510 voltage readings over a 0-30V d.c. measurement range. The user can easily set up the logging rate and start time, and download the stored data by plugging the module straight into a PCs USB port and running the purpose designed software under Windows 2000, XP or Vista(32-bit only). The data can then be graphed, printed and exported to other applications. The data logger is supplied complete with a long-life lithium battery.
