The SensorCheck™ app on your Apple or Android device, can connect wirelessly to Airmar’s TDT1000 Transducer Diagnostic Tester for the purpose of testing the performance of a transducer. Upon start up, the app will download all the updated transducer data from Airmar’s servers and make it readily available to test against. SensorCheck enables the user to start the test via the TDT1000, by first identifying the transducer connected, setting the parameters to test, and enabling the test to begin. Upon completion of the test, the SensorCheck app displays the test results and determines if the tested transducer’s performance is in range or out of range. The results of the test are automatically stored on the mobile device as well as Airmar’s servers. Test results can be shared via email or text to the boat owner or captain. Installers who are Airmar certified can also use the SensorCheck app to submit newly installed transducers for warranty.
