Use A Pair Of Needle-Nose Pliers To Grip The Contact And Pull It Out - Geodesic Sensor Net Technical Manual

9: Replacing GSN Parts
Use a pair of needle-nose pliers
10
to grip the contact and pull it the
rest of the way out of the
module (Figure 9-11). Be sure
that you pull the contact straight
out and not at an angle. If the
contact does not pull out easily,
it may be necessary to push it all
the way back into the module
and repeat the entire process
again.
It is important that you make sure that you always use the extraction tool
11
perpendicular to the connector and that when pushing or pulling the contact
out of the module that you work straight on and not at an angle. Occasionally,
it may be necessary to try several times to remove a contact without using
force.
Double-check to make sure that you have removed the correct contact, then cut
12
the contact from the end of the electrode wire.
13 Gently pull the electrode from the Net sensor housing by pulling on the
protruding end of the sponge. Slowly pull until the electrode wire comes free
from the sensor housing.
Replace the Electrode
1 Moisten the sponge of the replacement sensor with water or electrolyte.
If the sensor is one that connects to the Hypertronics plug at a perimeter
2
location, see the special perimeter location instructions on page 96. Otherwise,
proceed.
Gently thread the contact with its trailing lead wire through the flared foot
3
portion of the pedestal and through the cap. While holding the pedestal cap in
place, pull the wire until the top of the sponge is just touching the cap of the
pedestal.
If you have to use too much force to pull the sponge into the housing, trim the
4
sponge slightly for a secure but gentle fit.
