6.14.5.3 Start Scan
Start Scan will generate a scan of horn reactance showing resonant frequencies at the
zero crossover from capacitive to inductive reactance. Ideally there will be only one
resonant frequency. The screen will display the text “Scanning...” with the rate of update
for every dot being 1/4 second.

Press the Abort Scan button if you wish to abort the horn signature scan.
The result will appear on the screen.
