4.4.7 Stage 2 – Oxide Prevention
To prevent oxide build-up:
1. Apply a very short burst (not more than 0.5 seconds duration) of DeoxIT Gold GN5 spray to the
metal surfaces.
Avoid unnecessary spraying onto transmitter housing.
2. Wait 10 seconds.
3. Reapply one very short burst (not more than 0.5 seconds duration) of DeoxIT Gold GN5 spray to the
metal surfaces.
4. Allow any residue to run out of connector.
5. Wait 30 seconds for the application to dry.
Note. The surfaces may not appear completely dry after this time as a protective layer is left
behind when the carrier evaporates.
4.4.8 Completion tasks
To complete servicing of the plugs and sockets:
1. Reconnect peripheral devices in this order.
a. Sensor
b. Pressure transducer (if fitted)
c. Outputs
d. Communications
e. Battery pack / power
2. Refit protective caps on unused connection sockets.
3. For transmitters with built-in loggers and no GSM, re-program the real-time clock and date – see
Programming Guide (COI/FET2XX–EN).
Important (note)
It is strongly recommended that the account's factory default authentication password is
changed from the factory default on commissioning the flowmeter.
When changing a password, record it somewher secure, especially if each flowmeter has a
unique password. If a password is lost or unknown, it must be reset to the factory default
password using a single-use code that is specific to the applicable meter. This will reset the
flowmeter to the factory default settings and allow access to it.
