AquaMaster 3 FET200
Electromagnetic flowmeter Transmitter 4 Start-Up and Operation
OI/FET200–EN Rev. I 33
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.
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).
Note. The surfaces may not appear completely dry after this time as a protective layer is left
behind when the carrier evaporates.
