Data Logging
The DIVE gauge has a Data Logging feature that can be enabled
either when the gauge is purchased or enabled afterwards by the
user after purchasing a software enabling utility.
The Data Logging feature allows the user to log up to 5000
thickness measurements, including the A-scan graph, to the
gauge
’
s internal memory. These measurements are then retrieved
from the gauge by connecting to a computer which has Cygnus
CygLink installed, the logged measurements are then transferred
in to the computer and can be presented as a report, saved,
emailed or exported to a spread-sheet application.
The gauge uses an AutoLog feature to enable the diver to data log
measurements without pressing any buttons. Because the AutoLog
feature works on timing it is best to practice data logging before
the dive so you understand how to log the desired measurements.
AutoLog Feature
To remove the necessity for a “log” button but still enable th
e
diver to log measurements the AutoLog feature was developed.
The AutoLog feature uses timing of ‘stable measurements’ and ‘no
measurements’ to decide when to log a reading.
To data-log a measurement the diver simply HOLDS the probe
stable maintaining the measurement for a minimum set time
–
the
measurement is then automatically logged. To allow the next
measurement to be logged the diver must then RELEASE the
probe from the surface for a minimum set time
–
the gauge is
ready to log the next measurement when required.
In summary to Auto Log a measurement:
1
The diver places the probe on the surface and
obtains a stable thickness measurement.
2
The diver Holds the probe still and maintains the
stable thickness measurement.
