The MiniLog Model ML420, 4-20mAData Acquisition system is a compact, programmable acquisition device suitable for any short or long term, remote data logging application, for example water level measurement via 4-20mA interface of the AD375A, WL1100, WL3100 or similar. Very low quiescent current consumption, powered by user supplied 12VDC battery (internal 3.6V Lithium battery to maintain time). Events are stored in memory, which can be downloaded to either a PDA, laptop or desktop computer, or via modem. Memory Wrap feature ensures continuous data logging. An RS-232 serial port allows direct communication with a computer on-site. Logger requires a terminal emulation program and interrogation lead
