With its color monitor and internal memory the GL220 is a compact, lightweight, multi-channel data logger that provides 10 analog measurement channels, in addition to four channels each of discrete logic and pulse inputs. The GL220 also supports one external trigger input and four alarm outputs. The GL220 is equipped with a 2 GB internal flash memory to allow the direct capture of acquired data, and its built-in USB port may be used to connect any standard USB flash drive for incremental capacity. Alternatively, the USB interface may be connected to a PC to allow data upload in real time or from memory, as well as remote configuration and real time data acquisition.
