Sensor Guard Installation
A sensor guard must be installed in order to protect the ProDSS sensor being used with the ProSwap Logger. Damage resulting
from use without a sensor guard is not covered under warranty.
Carefully slide the sensor guard over the bulkhead and attached sensors/port plugs. Push the sensor guard toward the bulkhead
until the sensor guard threads align with the bulkhead threads. Then hand-tighten the sensor guard clockwise. If any resistance is
felt, loosen the sensor guard completely to prevent cross-threading. Incorrect installation may cause damage to the sensor guard or
bulkhead that is not covered by the warranty.
To help stabilize the sensors when profiling at deeper depths, a sensor guard weight is supplied with cable assemblies 4 meters and
longer. To attach the weight, carefully hand-tighten it clockwise on to the bottom of the sensor guard. If any resistance is felt, loosen
the sensor guard weight completely to prevent cross-threading. The bottom of the weight is threaded so that additional weights can
be added if needed. YSI recommends installing no more than 5 lbs of weight on the sensor guard.
