Density Tab – (instruments with Option 200)
The Density tab specifies the parameters of the measurement box used for measuring average signal
density of an area in the bitmap. The measurement box is also used by DPX Density triggering.
To measure the average signal density over a rectangular portion of the DPX bitmap, you can adjust the
size and location of the measurement area using these controls, or by dragging the measurement box in
the graph. You move the box by dragging the readout. You adjust the size of the box by dragging the
corners or edges.
