The AEMC L481 Simple Logger® II is a single channel bipolar DC voltage recording device powered by alkaline batteries. It is capable of measuring voltages from – 850 to + 850VDC. The choice of data storage modes and storage rates allow the operator to effortlessly configure the logger to optimize memory usage to the application at hand.

Extended Recording Mode (XRM®) and delayed start time are just two of the many application friendly features in this logger. Internal memory allows storing over 240,000 measurements, more than enough for most data collection needs.

User programmable scale and engineering units are available. Battery operation and compact size allows for installation in tight locations without the need for external power. A series of front panel LEDs provide a quick status of the logger’s state and memory usage.

DataView® application software is included, providing real-time viewing of measurement data, even while recording. Instrument configuration, data storage and report generation from a pre-defined template or operator custom designed templates are also standard features.
