You can perform the following operations using the measurementfunction.Operation of measurementItem Description SeeDistance between two points Measures the distance between the two points specified on an image. 12.2.1(p.147)Length of perpendicular line Length of a perpendicular line drawn from a point to a reference linedrawn between two points on an image.12.2.2(p.148)Angle Angle between two straight lines drawn on the screen. 12.2.3(p.149)Diameter and circumference of circle Diameter and circumference of a circle drawn with three points on thecircumference.12.2.4(p.151)Area of polygon Area of a polygon drawn on the screen 12.2.5(p.151)Distance between centers of two circles Distance between centers of two circles each drawn with three pointson circumference.12.2.6(p.152)Pitch length Length of several perpendicular lines drawn from desired points to areference line and distance between points (pitch distance).12.2.7(p.153)Operation of measurement resultItem Description SeeCanceling the last measurement result Cancels the last measurement result and erases displayedmeasurement results.12.3.1(p.154)Redoing cancelled measurement result Redisplays measurement result cancelled just previously. 12.3.2(p.154)Erasing an arbitrary measurement result Selects the number of measurement results and erases an arbitrarymeasurement result.12.3.3(p.154)Clearing all measurement results Clears rendered overlay contents including all measurement results. 12.3.4(p.155)Updating display of overlay Updates screen display and displays all measurement results. 12.3.5(p.155)Writing measurement results to CSV file Writes measurement results to a CSV file. 12.3.6(p.155)Displaying or hiding overlay Displays or hides overlay. 12.3.7(p.156)Switching calibration settings Selects [OFF] or any one of [M1] to [M7] for calibration settings to bethe reference for length measurement.12.3.8(p.156)Using mouseWhen stylus operation is not easy or accurate positioning is required, mouse operation is recommended.Use a commercially available USB mouse for operation.Clearing measurement results automaticallyMeasurement results on the screen are automatically cleared (erased) when the following operations areperformed.• Changing image mode: When [Image mode] is set to [ROI-L], [ROI-S], or [C.SCAN] in the [CAM MENU:CAMERA] long window, scales, annotations, and measurement results are completely cleared.• Playing back image: When an image is played back by the [VIEW MENU], annotations and measurementresults are cleared. The same applies to when playback is complete.• 2-window display: When [2WIN] display is set to ON/OFF in the [VIEW MENU], annotations and measurementresults are cleared.• Switching calibration settings: When calibration settings are changed by the [TOOL MENU] or [TOOLBAR],only measurement results are cleared.• All clear: When [ERASE ALL] is performed by the [TOOL MENU] or [TOOLBAR], annotations and measurementresults are cleared.On-Screen Measurement12Chapter
