6. Connections and Field Installation - Continued
CONNECTING THE DATA LOGGER TO THE FIELD CABLE
• Inspect the two O
-rings (C) on the open (connecting) end of the data logger. Make sure they are clean
and not damaged. (Figure 6.2)
• Look inside the open (connecting) ends of the data logg
er and the cable to see how the two mate
together. Note the two “keys” in the data logger and cable assemblies and the fact that they are different
sizes to ensure proper alignment. (Figure 6.1)
• Gently insert the data logger housing into the cable bac
kshell (knurled assembly). Hold the data logger
in one hand and the cable in the other near the backshell. While applying slight pressure to push the two
parts together, slowly rotate the data logger assembly in the backshell until the keys align. When that
happens the housing will slip into the backshell assembly an additional inch and you will no longer be
able to rotate the level data logger while holding the cable.
• Now that the keys ar
e aligned and seated, grasp the data logger in one hand and the knurled backshell
in the other. While applying slight pressure to push the two parts together, screw the backshell onto the
data logger housing. Continue threading the parts together until they are fully mated, leaving no visible
gap where the backshell meets the data logger housing.
