The Megger PAT400 Barcode Scanner is compatible with downloadable Megger PAT testers such as the PAT410, PAT420 and PAT450. It can quickly read appliance ID barcode labels and convey this information to the tester where appliance information can be recalled to the screen and results can be saved logically to the right appliance. This speeds up the PAT testing process as there is no need to enter appliance information manually before testing.
