Chapter 12 On-Screen Measurement153Adding Annotationsand Measuring12.2.7 Measuring Pitch DistanceYou can measure length of several lines drawn from desired points to a reference line. For the second and subsequent points,difference between points (pitch distance) can also be measured.1 Display the toolbar and press the [SHOW ALL] button.2 Press the [COLOR] button to select color ofmeasurement results.3 Press the [PITCH MEASUREMENT] button.A blue frame appears around the button.4 Specify two arbitrary points (A and B in the figure) onthe screen to draw a reference line.A reference line is drawn from the starting point to the endpoint.5 Specify arbitrary points (C and D in the figure) you wantto measure.If you specify a point, a perpendicular line is drawn from thepoint to the reference line. The length of the perpendicularline is shown.For the second and subsequent points, distance from theprevious point (pitch distance) is shown as well as thedistance to the reference line.6 To display or hide the measured result, switch todisplay or hide overlay.You cannot selectively display or hide only the measuredresult. Switch to display or hide the entire overlay.7 To end measurement, press the [PITCHMEASUREMENT] button to deselect the tool.Measuring Pitch DistanceUndoing and redoing measurementYou can cancel and redo measurement by pressing the [UNDO MEASUREMENT] or [REDO MEASUREMENT]button respectively.Measurement result display• If the setting of calibration is changed, all measured results are cleared.• The line width and character size of measurement result can be changed on the [TOOL SET: MAIN] screen.• When stylus operation is not easy or accurate positioning is required, mouse operation is recommended. Use acommercially available USB mouse for operation.23, 7465111
