Manual revision 016 Section 5: Routine Maintenance and Calibration SBE 49

Section 5:

Routine Maintenance and Calibration

This section reviews corrosion precautions, connector mating and

maintenance, conductivity cell storage and cleaning, pressure sensor

maintenance, O-ring maintenance, plastic housing handling instructions,

replacing optional AF24173 Anti-Foulant Devices, and sensor calibration. The

accuracy of the FastCAT is sustained by the care and calibration of the sensors

and by establishing proper handling practices.

Corrosion Precautions

Rinse the FastCAT with fresh water after use and prior to storage.

All exposed metal is titanium; other materials are plastic. No corrosion

precautions are required, but direct electrical connection of the titanium to

dissimilar metal hardware should be avoided.

Connector Mating and Maintenance

Clean and inspect connectors, cables, and dummy plugs before every

deployment and as part of your yearly equipment maintenance. Inspect

connectors that are unmated for signs of corrosion product around the pins,

and for cuts, nicks or other flaws that may compromise the seal.

When remating:

1. Lightly lubricate the inside of the dummy plug/cable connector with

silicone grease (DC-4 or equivalent).

2. XSG Connector - Install the plug/cable connector, aligning the raised

bump on the side of the plug/cable connector with the large pin

(pin 1 - ground) on the FastCAT. Remove any trapped air by burping or

gently squeezing the plug/connector near the top and moving your fingers

toward the end cap. OR

MCBH Connector – Install the plug/cable connector, aligning the pins.

3. Place the locking sleeve over the plug/cable connector. Tighten the

locking sleeve finger tight only. Do not overtighten the locking sleeve

and do not use a wrench or pliers.

Verify that a cable or dummy plug is installed before deployment.

Note:

See Application Note 57: Connector

Care and Cable Installation.

CAUTIONS:

• Do not use WD-40 or other

petroleum-based lubricants, as

they will damage the connectors.

• For wet-pluggable MCBH

connectors: Silicone lubricants

in a spray can may contain

ketones, esters, ethers, alcohols,

or glycols in their propellant. Do

not use these sprays, as they

will damage the connector.
