The data can then be graphed, printed, and exported to other applications. The data logger is supplied complete with a long-life lithium battery. Correct functioning of the unit is indicated by flashing red and green LEDs. The data logger features a pair of screw terminals, and is supplied with a set of measurement leads with alligator clip terminals.
