Operations Guide

Prior to using the Rotating Manipulator the following steps are necessary:

• Mount the Cygnus Ultrasonic Thickness Gauge on the ROV.

• Install the software.

• Configure the software for the Cygnus Ultrasonic Thickness Gauge.

• Check the buoyancy and adjust the ballast weights as necessary to achieve the desired buoyancy and trim.

Operating the Swing Arm Module

The Cygnus Ultrasonic Thickness Gauge is operated by the use of the Hand Controller.

Swing Arm Module Activation Buttons

The Swing Arm Module uses the standard manipulator buttons with the following actions:

	Manipulator Open = Swing Arm Module Up
	Manipulator Close = Swing Arm Module Down

Press the desired button to activate that function of the Rotating Manipulator.

Operating Tactics

The Cygnus Ultrasonic Thickness Gauge operates best on flat surfaces. Press the gauge flat against the surface it is in contact with, if the gauge is not flat, reposition it using the Hand Controller until it is flat.

It is imperative that the surface being measured is smooth, free of corrosion and biofouling. It can be difficult to take measurements when these conditions aren't met and depending on the level of corrosion or bio fouling, the Thickness Gauge could fail to take a reading. When these conditions are present it is best to scrape off the corrosion and biofouling before attempting to take a measurement.
