Revision B
8. Clean any residue and grease from the threads and adjacent areas including the O-ring
groove on the Tracer body with a clean, lint-free cloth.
9. Before the new O-ring is replaced, apply a thin coat of silicone vacuum grease (in
Maintenance Kit) to the O-ring.
Use
a
very small
amount of grease on your thumb and index finger.
Place the O-ring between these two fingers and gently pull the O-ring through the
grease until a light coating of grease completely covers the surface of the O-ring. The
surface of the O-ring should be glossy.
10 Carefully place the O-ring in the O-ring groove at the bottom of the Tracer body threads.
Avoid dragging the O-ring across the threads, they could cut or nick the O-ring,
compromising its sealing capability.
The best method of O-ring installation is to start from the probe side and place one part of
the O-ring in the O-ring groove.
Slightly
stretch the O-ring with your fingers to position it
completely over the O-ring groove, and then release it.
DO NOT STRETCH THE O-RING ANY MORE THAN NECESSARY. DO NOT DEFORM
THE O-RING.
Always replace the O-ring when the Tracer battery compartment has been opened
.
The Tracer is now ready to reassemble with a new battery. We strongly recommended that
Tracers are
NOT
left unassembled. Damage to components could occur making Tracers
unusable.
11. Obtain a fresh, conditioned battery. (See conditioning procedure in the next section.)
Verify that the temperature range of the FRB Tracer and battery are matched. Standard
Temp batteries are rectangular and can be used in FRB Tracers with a
WHITE
or
RED
ring. LoTemp batteries are coin-shaped and should only be used in Tracers with a
BLUE
ring.
Standard Temp batteries (rectangular) and LoTemp batteries (round) have different pin
configurations. The FRB Tracer sockets for Standard Temp and LoTemp Tracers are
designed to accommodate only the appropriate batteries. So mixing up batteries and
sockets is unlikely.
12. Holding the Tracer in one hand and the battery in the other, align the battery pins in the
sockets on the Tracer.
13. Press the battery into the sockets until seated. This does not take much pressure. Do not
twist or turn the battery as it is installed, as damage to the battery pins or Tracer sockets
could result.
14. Place the battery cover squarely over the Tracer body threads. Begin to screw the cover
in a clockwise direction. Be careful to not cross thread the cover on the Tracer body
threads. The cover should screw on smoothly and easily until the O-ring becomes
engaged.
