Distance Measurement with Website Display
confocalDT 2421 / 2422
1 Stop pauses the chart; you can still use the data selection and zoom functions.
Save
opens a Windows selection
dialog for the file name and save location to save the last 10,000 values in a CSV file (separation using semico-
lon).
2 All changes only become effective when you click on the
Save settings
button.
3 In the left-hand window, the signals of channel 1/2 to be displayed can be switched on or off during or after the
measurement. Inactive curves are grayed out and can be added by clicking on the check mark. The changes
become effective when you save the settings.
You can show or hide the individual signals using the eye symbols
. The calculation continues in the back-
ground.
• 0xSHUTTER: Exposure time
• 0xINTENSITY: Signal quality of the underlying peak in the video signal
• 0xDIST: Distance signal curve over time
4 To scale the axis in the graph for the measured values (Y axis), you can use
Auto
(= automatic scaling) or
Ma-
nual
(= manual scaling).
5 The current values for distance, exposure time, current measuring rate and time stamp are shown in the text
boxes above the graph. Errors are also displayed.
6 Mouseover function. When the chart has been stopped and you move the mouse over the graph, points on the
curve are marked with a circle and the associated values are displayed in the text boxes above the graph. The
intensity bars are also updated.
7 The peak intensity is displayed as a bar chart.
8 Scaling the x axis: During an ongoing measurement, you can use the left-hand slider to enlarge the entire signal
(zoom). The time range can also be defined using an input field under the time axis. When the chart has been
stopped, the right-hand slider can also be used. You can also move the zoom window with the mouse in the
center of the zoom window (four-sided arrow).
