The OM-CP-VOLT101A voltage data logger provides a low cost solution for logging single channel DC Voltages. Its high accuracy and 16-bit resolution place this product at the forefront of low level DC voltage recording devices. This data logger is ideal for accurately measuring and recording battery voltages, sensor output signals, photovoltaic studies, as well as many other low level DC voltage sources. With user programmable engineering units, the user can scale the input voltage automatically. The OM-CP-VOLT101A is available in four different input ranges: 160 mV, 2.5V, 15V and 30V versions. Data retrieval is simple. Plug the device into an available USB port and our easy-to-use software does the rest. The software converts a PC into a real-time strip chart recorder. Data can be printed in graphical and tabular format or exported to a text or Microsoft Excel file.
