Strain-rate (nanostrain/second) = scale factor * iDAS values * sampling freq. (Hz) / gauge length (m).
Here, scale factor = 116 (nm) / 8192, sampling freq. = 1000 (Hz), gauge length = 10 (m).
In other words, the values reported by the iDAS should be multiplied by 11600/8192 to convert to strain-rate with unit of nanostrain/second.
