4. Disconnect the DVM lead from connector pin L on the recorder
end and, with the other DVM lead still connected to pin M, confirm
that pin M is infinite with respect to all the other connector pins.
You have now "buzzed out" the top two connections (L and M) shown in
Figure 30, for the two wires in the white-black pair. Now repeat Steps 1
through Step 4, but test connector pins A and B and the two wires in the
green-black pair.
Follow Steps 1 through 4 for each pair of connector pins and wire-pairs in
he remaining five pairs of wires and 10 connections shown in Figure 30.
Carefully check that all other pins in the connector are infinite with respect
to the connector pin you are testing, that the two wires in each pair can be
linked at the EpiSensor end without problems, and that the pin is infinite
with respect to all the other connector pins. As you test, carefully follow the
right end of Figure 30.
Caution:
Do not proceed to the shield-to-shell testing until all the pairs of
insulated conductors have passed the four test steps above.
Once you’ve completed testing all the pairs of insulated conductors, test the
connection of the wire shields to the recorder end of the connector shell.
1. At the EpiSensor end, take the white-black pair of wires and use a
test lead jumper to connect the white wire to the exposed drain
wires.
2. When that is done, the DVM at the recorder end should show that
pin L is connected to the recorder-end connector shell and to pin U.
The DVM should measure <1.5
%
per 100' of cable. If so, remove
the test jumper at the EpiSensor end of the cable.
3. At the recorder end, disconnect the DVM lead from connector pin
L and confirm that the connector shell and pin U are infinite with
respect to all other connector pins.
4. With the preliminary cable testing completed, disconnect all test
equipment.
5. At the EpiSensor end, gather the 2" of wires, shields, cord, etc., that
you stripped back; cut off these exposed elements and discard
them.
Caution:
Do not connect the recorder connector to the recorder until you
have installed the EpiSensor connector and have completed the final testing
described at the end of the cable assembly process.
If all the recorder-end connections passed the above test, proceed to the next
section.
