The CPX-930 uses a 1D/2D barcode scanner built into the back of the tester to scan the VIN of the vehicle being tested. This number is then cross-referenced with original equipment manufacturer’s battery specifications in the tester’s database and displayed on the tester screen.
Barcode Scanner: Located in the upper left portion on the back of the tester.

Hold Steady: Hold the tester steady when scanning the VIN barcode. This allows the user to clearly see the barcode and the scanner to focus on it.
Clean Barcode/Windshield: Surface dirt can interfere with the scanning process. If necessary, wipe the VIN barcode with a cloth or your finger to remove any surface dirt.
Lighting/Glare: If sunlight is shining directly onto the VIN barcode, try pivoting the scanner slightly up or down to reduce any glare.
NOTE: Barcode types supported by the CPX-930 include: 1D – Code 39, Code 128, UPC, Codabar, and GS-1 Limited. 2D – PDF417. QR Code: Model 2 and Data Matrix.
