CS475, CS476, and CS477 Radar Water Level Sensor
3. Initial Inspection
When unpacking the equipment, do the following:
• Unpack the unit in a clean, dry area.
• Inspect the equipment for any damage that occurred during shipping or
storage.
• If the equipment is damaged, file a claim against the carrier and report the
damage in detail.
4. Quickstart
This Quickstart uses the default settings (see TABLE 4-1), which are used in
most circumstances.
TABLE 4-1. Default Settings
Setting Default
SDI-12 Address 0 (change only if two sensors are connected to the same
port; valid addresses are 0 through 9, A through Z, and a
through z; see Appendix B.1.3, Query/Set the Address)
Units of Measure 1 = feet (see Appendix B.1.4, Set Units)
Water Conditions 1 = smooth (typical peak to trough of wave ≤4 inches;
see Appendix B.1.5, Set Water Conditions)
Power Operation
Mode 1 = on (sensor is always on until new power operation
mode command received; see Appendix B.1.6, Set
Power Operation Mode)
Detailed information about all of the settings and information on
changing the settings are provided in Appendix B. NOTE
4.1 Step 1 — Mount and Align the Sensor
1. Choose an appropriate site away from obstructions and over the smoothest
part of the water (see Section 7.1, Site Selection).
2. Center the sensor beam a minimum of 2.5 m from any obstruction in the
measurement range. Obstructions to be aware of include excessive waves,
splashing, pipes, wires, and logs. Note that the radiation beam spreads as
it leaves the sensor (see TABLE 4-2 and TABLE 4-3).
Usually the beam path is 10° for the CS475, and 8° for the
CS476/CS477. NOTE
