[Boatanchors] Measuring Swinging Choke values

[Carl]

Possibly it is out of range of the instruments ability? Figure on a 5:1 
swing ratio with 5-25 and 6-30H being some typicals.Ive also seen 10:1's

Ive no trouble testing them with a hand held LCR meter and the results are 
almost identical on a real bridge.
