1. Overview

The Deep C Meter 300 AD is a complete ROV-interfaced cathodic protection monitoring system.

The system comprises ve basic parts:

1.1 LED readout

Triple voltmeters housed in a Delrin pressure housing.

1.2 Contact probe

Twin element, tip contact CP probe (Polatrak® Model ROV-II™).

1.3 Flying lead

Three-meter-long umbilical that connects the probe to the readout.

1.4 Power whip

Two-meter-long umbilical that interfaces with the ROV for power and data output.

1.5 EFG probe (optional)

Can be added as an upgrade to the standard package.

1.6 The Deep C Meter 300 AD™ has the following upgrades from previous versions:

• Smaller pressure housing

• Combines ROV-II™ and Polatrak EFG pressure housing

• Programmable ultra-bright LED displays with brightness adjustments

• Digital output (RS232 – standard ASCII string)

• ROV 24V DC powered, which eliminates the need to open the pressure housing to change batteries

4. LED readout components

The readout unit has three major sub-assemblies: The pressure housing, articulated mount and ying leads.

4.1. Deep C Meter 300 AD™

4.1.1. Pressure housing - The pressure housing is made from Delrin and is rated for water

depths of 300 meters (1,000 feet).

4.1.2. Lens - One end of the housing contains an acrylic lens that seals on the pressure housing
with o-rings. Four stainless-steel screws keep the lens seated in the pressure housing. Access

to the inside of the pressure housing is gained by pulling the lens. Removing the lens in the eld

should be avoided wherever possible.

4.1.3. Bulkhead connector - The back end of the pressure housing is sealed with three bulkhead
connectors. These connectors thread into the back of the pressure housing and also seal with
o-rings. It should not be necessary to remove these connectors during normal maintenance. Blank
(dummy) plugs are provided and should be in place whenever the mating connector is removed.

4.1.4. Voltmeter module - The digital voltmeter module is located within the pressure housing.
The module contains three independent LED displays. Default factory range is ± 2499 mV DC on
the top two display lines. The lower display line is set to ± 199.9mV DC. The meter is powered by
24VDC nominal power but will function between 8-36VDC.
