Introduction
Cygnus DIVE Underwater Thickness Gauge
The Cygnus DIVE Underwater Thickness Gauge has been
specifically designed for the professional diver undertaking metal
thickness surveys in both shallow and deep water sites. It has
been design to withstand the extreme environments encountered
while providing quick, clear and accurate metal thickness
measurements using the Cygnus Multiple Echo technique and
Single Echo / Echo-Echo options.
The Cygnus DIVE Underwater Thickness gauge is pressure rated to
a maximum depth of 300 meters sea water (984 ft).
The gauge can be worn on the diver
’
s fore-arm allowing one hand
to remain free while carrying out the thickness survey. A bright
colour display shows the thickness measurement in large numbers.
Thickness measurements are further backed up by an A-scan
display. Measurement data can be sent to the surface via a RS-
485 serial data link where they can be data logged and used to
produce a survey report using Cygnus
’
CygLink software.
Measurements can be displayed in Metric (mm) or Imperial (inch)
units and measurement resolution can be selected from 0.01
1
,
0.05 or 0.1 mm, (0.001
2
, 0.002 or 0.005
inch). Thickness
measurements can easily be calibrated to a known thickness or to
a known Velocity of Sound.
The gauge is a solid-state electronic instrument which, under
normal operating conditions, will give many years of active
service.
Although designed for ease of operation first time users
should carefully read this manual to familiarise themselves
with the features of the gauge
