you will need to disconnect the cable from the underwater connector to the receiver board. This
cable is highly sensitive to noise and should not be modified.
To close the conditioning module, first inspect and clean all o-rings and o-ring surfaces. Replace
the o-rings if necessary. Next, connect the cable from the underwater connector to the receiver
board and make certain all cables from the optional sensors are securely connected (see §4.7.2 for
a description of these cables). The three screws that secure the end cap to the conditioning mod-
ule housing are slightly asymmetric and can only be installed in one orientation; this ensures the
correct alignment of the compass/tilt sensor with respect to the probe. Install the end cap and se-
cure with the three #6-32 screws.
Note: The cables and electronics in the conditioning module are very sensitive to noise and
should not be modified. If you have any questions, contact SonTek. When opening the
conditioning module, be sure to install a fresh bag of desiccant and/or purge the housing
with nitrogen before closing. This is particularly important in humid climates to prevent
condensation.
