Real-time readings are displayed in the Setup window, allowing you to verify that your data logger is working correctly before placing it in the field.

For added presentation power, add comments, change graph colors, zoom in on specific portions of data, and display your data using custom engineering units. Print or copy and paste graphs into your reports and presentations. Select all, or portions of the table and copy and paste into your favorite Windows program.
