Figure 36: Completed assembly of recorder-end of cable 840356
Testing Connector Assembly #1
Now do a "buzzing out" test on the recorder-end of the cable to make sure
the correct wires are connected to the correct solder cups (per the schematic
in Figure 30), and that none of the wires were shorted in the assembly
process.
For this testing procedure you need:
!
A digital voltage meter
!
A utility knife
!
A wire stripper
!
A test lead jumper with clips
To prepare the EpiSensor-end wires as response conductors:
1. Strip back 2" of the cable’s outer jacket.
2. Cut off that 2", along with the cellophane, white string, and foil
shields that it covered.
3. Separate the drain wires and insulated conductors.
4. Strip off 1/8" of insulation from all of the insulated wires.
5. Make sure to position each wire so that its exposed surface has
no
contact with any other wire.
Now, using the DVM, test the connection of the conductor pairs in the
recorder-end of the assembly: First set the DVM to measure resistance in
the range of several hundred ohms. Then:
1. At the recorder end of the cable, connect one DVM lead to
connector pin L (at the top right in Figure 35). Then, with the other
DVM lead, check that all other pins in that connector are infinite
with respect to pin L.
2. At the EpiSensor end of the cable, have another technician take the
white-black wire pair and use a test-lead jumper to connect the
white wire to the black wire.
3. When that is done, the DVM at the recorder end should show that
pin L is now connected to pin M. The DVM should measure <2.5
%
per 100' of cable. If it does, have the other technician remove the
test jumper at the EpiSensor end of the cable.
