ViewData™ software is used to show the output of Pinnacle tiltmeters. The program reads data from .ptx or .upd tiltmeter data files and displays the X and Y channel tilt time series. The instrument’s supply voltage and temperature time series can also be plotted. There are many options to tailor the output graphs. The program can also be used to export the data into ASCII format for use by third party software and to explore the raw data throughout the file.
