6. Part Before Checker inspects your part it must detect that your part is present Checker can detect your part in two ways 1 Checker can detect parts using a Part Finding Sensor Simply create a Part Finding Sensor and place it over a part feature that Checker can always see 2 You can use an external photoelectric sensor to tell Checker that the part is present Checker uses the rising edge of the input signal If you use both an external photoelectric sensor and a Part Finding Sensor both the photoelectric sensor and the Part Finding Sensor must indicate that the part is present before Checker will inspect the part 3 Inspect My Part Create an nspection Sensor for each part feature that you want to check The result of an Inspection Sensor can be pass or fail The results of all Inspection Sensors must be pass for Checker to pass your part If the result of any Inspection Sensor is fall Checker will fail your part Checker provides three types of Inspection Sensors Brightness Sensors detect bright features Contrast Sensors detect high contrast features and Pattern Sensors detect matching patterns Brightness Sensor Contrast Sensor Pattern Sensor ee 000 p GI hmmm o gt TT To create an Inspection Sensor click on the feature to check then adjust the Sensors threshold so that good parts are above the threshold and bad parts are below it For Brightness and Contrast sensors you can adjust the Sensors range and
