The data measured via single or multiple monitoring are listed in a table providing the following information
  • Date/Time
  • Axis X, Y, Z
  • ISO value
  • AVG value
  • MAX value
  • Temperature
  • Type of Probe (clicking on the specific field opens a window with data from the corresponding probe).
  • GPS Lock/Off
  • GPS coordinates

 

In the amplitude/time mode pan, zoom, min and max functions are available, and the operator can select linear or logarithmic scale. The graph allows the display of each single axis, the resulting, of the mean and temperature value.
