Cursor, Zooming and Panning is done the same way as in the Records graphs. See section Graph ControlsGlobal Level Calculations .

 

The application automatically calculates the global levels or equivalent dose corresponding to the displayed data.

 

The global values can be calculated according to several methods. At the time of this writing we offer the linear ISO (Q=3) method, as well as the OSHA (Q=5) method. Other methods may follow.

 

These global values are calculated from the Leq curve (white curve). In order to obtain the global values, the Leq MUST BE among the recorded statistics.

 

The global values are calculated from the visible part of the graph only. Play with the zoom and pan functions to eliminate portions at the beginning and end of the recording from the calculation.

 

Graph ControlsThe auto-scale button can be pressed or released to obtain an automatic or fixed vertical scale. When the graph is in fixed scale, writing directly in the values of the end-scale markers sets the scale to fit those values.
