Claim Text:
1. A semi-automated method for determining the wave return time of a tensioned line correlated to sag-tension charts, comprising the steps of: attaching an electronic wave return time determining device to the tensioned line, said device comprising: automatically determining an ambient temperature via the electronic wave return time determining device; inputting a fixed number of mechanical waves for the electronic wave return time determining device; automatically detecting an initial inducement of a mechanical wave on the tensioned line via the electronic wave return time determining device; automatically detecting a plurality of at least one of a maximum acceleration of the induced mechanical wave and reversal of acceleration of the induced mechanical wave on the tensioned line via the electronic wave return time determining device, wherein the automatic detecting is triggered upon passing a pre-determined delay threshold; automatically calculating a total time delay for the fixed number of mechanical waves from the induced mechanical wave on the tensioned line; and calculating a line sag using the total time delay obtained from a sag-tension chart for the tensioned line.
