    Introduction 5. TESTING AND FAULT FINDING 5.1 Introduction The ADTS 405 contains a built-in, self-test and diagnostic system. The system continuously monitors the performance of the unit and at power-up carries out a self-test. Warning and error messages are displayed during normal operation if out of range values are entered or if faults occur. This section details the standard serviceability test and the error messages and codes that can be displayed.

    Standard Serviceability Test The ADTS 405 displays any detected errors. Check that the power-up sequence continues through the following stages without error: • Calibration date. • Self-test. • Measuring ground pressures. • Equalizing system pressures. Check that the display then changes to show measured altitude and airspeed (CAS or TAS) values.
