Install the instrument Alignment Probe onto the instrument base plate using two of 1/4-20 x
0.625” Hex Socket Head Flat Countersunk screws as shown below (See Figure 8). The
alignment probe mates with the Alignment Fixture that is mounted within the Underwater
Housing. This fixture holds the instrument’s front plate rigidly in place within the Underwater
Housing.
When installing the Alignment Probe, carefully note its orientation and placement; it must
be placed exactly as shown in order to mate correctly with the Alignment Fixture
mounted within the enclosure.
Make sure that the lens cover has been removed from the instrument’s foreoptic.
