Pocket Logger Software

Pocket Logger Software (free download below) is an easy-to-use Windows program for the Pace XR440 Data Logger. Use the software to quickly set the XR440 for sensor type, start and run modes, sample rate, channel labels and more.

The user can view sensor values in real-time, transfer data to computer (data logging continues without interruption), graph, export data and much more.

The software's context sensitive help includes a hardware reference manual.


Data is viewed graphically in up to four viewports. Channel data traces can be combined into a single viewport or separated as desired. Zooming is controlled by dragging the mouse over a section of the graph. Pointing the mouse at any data point displays its time stamp and value.
