Typical Operation
1. At the start of each shift an automatic functional test verifies the performance of all vital safety circuits.
2. The product's model number and serial number are scanned in. Once the product is identified, the test station knows the test parameters to apply. It holds those parameters until a new product is entered.
3. The safety type compliance tests are conducted.
4. Operational tests are then performed.
5. If action or inspection points by the operator are required, they are displayed on the screen.
6. The operator enters the inspection results using a bar-coded list of common responses; special information can be entered using the keyboard or touch screen.
7. An out of tolerance condition causes the tester to remove all electrical power, alert the operator with a visual and audible alarm. The reset button must be operated to continue.

Parameters for the product are presented.

Inspection Codes can be uploaded with a barcode scanner.


Various screens provide the operator with real time test parameters, test results and special messages in the language of their choice.


 Results from all test stations are displayed.
Tolerance Limits
Parameter are tested to the tolerance limits you establish for each product type. 
Real-Time Data Display
Data is displayed on the screen as the test progresses.
Compliance and Operational Tests
All compliance and operational tests can be conducted from a single test station.
For products that are to be serviced in the test area, a diagnostic screen directs the operator to the probable cause based on test data.
