Make long as possible within geolink dimensions to allow for several recuts. Don’t relieve pin for easy recut 1. Only one screw per clamp bolt or EOR , therefore only one side lines up 2. No loctitie only hand tight but ensure hole clean before install 1. Tighten clamp bolt slightly more to line up castellation with the locking screw , otherwise back off slightly to line up 2. Clamp bolt castellations are offset and only one will line up and one set screw installed 1.Metal cleaner and rags only for critical seal areas 2.Geolink provide drawings for all subs and customer manufactures themselves .

In general for a the start point of a pulse to be detected by the SIB, the drop in pressure must exceed the THRESHOLD level for a period of time greater than the WIDTH LIMIT (default 05 or 0.25 secs). The end point is when the pulse reading goes below the THRESHOLD Level for a period of time greater than the WIDTH LIMIT. The WIDTH of the detected pulse is equivalent to the total time above the Threshold Level (secon
