There are some notes in the manual, but here are some additional points:
- Check that the casing is deep enough to contain the chain of sensors. Note that a 60 meter chain will not fit properly in a 60 meter casing. The bottom sensor must not touch the bottom of the casing and the top of the chain should end well below the top of the casing. Also allow some room for the suspension kit at the top. If the casing is not deep enough, shorten one of the gauge tubes. Be sure to note the final length.
- Fit gauge tubes to each sensor. Test the connection for rigidity.
- Use cable ties to hold signal cables neatly against the gauge tubes. Signal cables must not touch the walls of the casing.
- Use cable ties to hold connectors neatly against the gauge tubes. Put one cable tie above and one below the connector to ensure that it is not pulled apart.
- When the entire chain is in the casing, try lowering it below the intended depth and then pull it back up to the depth. This should put the chain into tension and theoretically shorten the time needed before a baseline reading can be acquired.
