The meter constantly performs self-diagnostics and can display various error messages. If an error occurs, the error code is dis-played in the main loop. All windows, however, can still be accessed by pressing the key. The error message disappears automatically as soon as the source of the error is corrected. All errors that occur for longer than 6 minutes without interruption, are saved in the error memory.
