Inspection Cycles During setup, sites are given a priority of either Every Cycle (EC) or General
(G). The amount of sites inspected during each cycle is set using the min sites/
cycle parameter, this must be set to at least the amount of every cycle sites. As
the name suggests, EC sites are inspected every cycle. General sites are
inspected depending on the value of the min sites/cycle parameter and the
number of EC sites as follows:
Number of general sites inspected per cycle = Min sites/cycle parameter - EC
sites.
The general sites are inspected in rotation as shown below.

In the example below, seven sites have been setup, with two given the priority
of and five given the priority of .
The min sites/cycle parameter is set at 5. As there are two EC sites, this leaves
three G sites to be inspected at each cycle as shown.

Lighting The lighting level for 2D Inspection is software controlled. For a more detailed
description of the camera and optical unit refer to the Technical Reference
manual - Camera and Vision Systems Module chapter.
The grey camera lighting parameters and functions are shown below. Each
lighting group can be set by the operator to a level between 0 to 15, where 15
is the brightest.

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.
