Select which histograms you are interested in with the controls in this box:

●

The "Reference" check box tells the GUI to display the optical reference histograms. The optical

path for this histogram is entirely within the sensor package. The target objects in the field of

view of the sensor do not influence this histogram.

●

The "Measurement" histograms show the reflected light from the objects in the field of view of

the sensor.

The Histogram "Snapshot" button allows the user to "freeze frame" the current histogram plot while

still plotting the measurement histograms concurrently. This gives you the ability examine two

histogram plots (one current, the other one a snapshot) at the same time in the histogram plotting

area. Releasing the "Snapshot" button deletes the saved snapshot histograms.

Information

The 8x8-histogram view is not enabled in the EVM GUI. It automatically hides this element in 8x8

mode.

Information

To get the fastest ranging time, disable all histogram display check boxes here.
