A revolutionary new tool for Nortech PDx7x parking detector installations! The DU Diagnostics mobile application is available for anyone to download, but you will need to have the latest Nortech PDx7x parking detector(s) and a Nortech DU700 unit on hand. The DU700 unit attaches to the front of a parking detector and transmits data via Bluetooth to your phone/tablet. This application allows you to interface with the received data. The interface will provide you with the current status of the loop installation of the parking detector, including: > Loop frequency and inductance change > Loop frequency drift > Detection sensitivity > Loop status > Detector configuration The DU Diagnostics application also allows you to capture other pertinent installation details (such as loop dimensions, site information, etc...). For your convenience, or for site sign-off, a PDF with all of these details can be generated. You can then save, email or print this PDF.
