2. Remove the 3 M5 x 20 socket cap screws in the connector bulkhead, using the Allen
key provided.
3. Without twisting or putting undue stress
on the Subconn connector slide the
bulkhead and attached battery pack out of
the main housing. A slot between the
tube and the bulkhead allows levering with
a screwdriver if necessary. Take care not
to scratch the bore of the tube.
4. A lead connects the battery pack to the electronics inside the tube. This may be
disconnected at the battery pack if required, for ease.
5. Replace the batteries.
6. Check the condition of the bore seal o-rings, and apply a light coating of silicon
grease. Ensure that both they and the anti-extrusion rings sit in the groove correctly,
and are free from damage. Replace them if necessary (refer to Section 4.2).
7. Reattach the connector to the electronics if necessary, and gently slide the battery
pack back into the tube, ensuring that the fixing holes are correctly aligned. Again,
take care not to scratch the bore.
8. Replace the 3 x M5 screws, using a small amount of copper grease (supplied). Do
not force the screws, just tighten firmly.
9. Finally, slide the instrument back into the protective cage. Note that the clamping
brackets are offset, and that the sensor end of the instrument should lie at the long
end of the cage.
