Image Recording Selecting Save Image saves the inspection object data using the save object
command. This option is only available if image recording in set preferences
is set to VP or PC disk.
It is recommended to use PC disk only for image recording. When saved the file
name is inspnnnn.im2, where n is an incrementing number.
The first image saved after initialization is insp0001.im2.
NOTE
VP disk saves to the Vision HD if fitted.
Inspection Setup Correct inspection setup is the key to effective inspection. By following the
steps of the setup sequence, shown in the summary below and the setup guide
over the page, effective inspection may be achieved. Refer to the 2D Inspection
Setup section of this chapter for step by step procedures on inspection set up.
