Modules of the LAP® Series Radar Wind Profilers are equipped with built-in diagnosis tools which digitally communicate with a dedicated Monitoring Unit. The Monitoring Unit continuously verifies the proper function of all components. It creates and logs an extensive functionality report in user-defined intervals. The system status is stored together with the output data and optionally reported to the user's data environment over protocols such as SNMP. A summary of the system status is displayed on a toggling monitoring screen.
