5. Product Description
・
The Model CVR–010 is a single–frequency navigation echo sounder designed to
comply fully with IMO Resolution MSC.74( 69) Annex 4, and is type–approved by BSH
on the basis of compliance with DIN EN ISO 9875 and relevant IEC requirements for
wheel mark certification.
・
Featuring a 5.7–inch daylight–viewing, LED–backlit color TFT LCD screen, the
equipment displays the echogram using a total of seven user–definable
ease–on–the–eye analog strength–level colors that represent various layers of the
bottom stratum. The display can be set to show the bottom contour alone in a single
color via a menu–guided procedure.
・
Digital depth readout is also available using easy–to–read large fonts with a clear
on–screen indication of the reference of measurement (from the waterline, the transducer
or the keel)
, and in meters, fathoms or feet. To comply with the IMO resolution, the depth
reading must be indicated in meters for navigational purposes.
・
With an optional GPS sensor plugged in or an external GPS data source connected, the
ship’s LAT/ LON coordinates, speed and heading data will also be displayed at the
same time.
・
A battery–backed realtime calendar clock is built in to indicate the date and time in UTC
or in the desired local time at all times.
・
The built–in alarms include depth alarm, bottom–missing alarm, power failure/low
voltage alarm and power removal/shutoff alarm.
・
With an appropriate GPS sensor plugged in, or an external GPS-based data source
connected, the time is automatically referenced to the atomic–precision GPS time.
・
Up to 12 hours of sounding data will be stored in non–volatile memory at approximately
two–second intervals, together with associated date and time, range in use plus
position coordinates (with an optional GPS sensor plugged in or GPS source connected).
・
The user can review the stored data across any 15–minute segment at any point in time
over the past 12 hours through a specially designed window easily accessible with a
devoted key.
・
The depth sounding history can be graphically displayed to show how the depth varied
over the past hours. Detailed data is also available digitally via another window that can
also be accessed with a single keystroke.
・
The data can be output on demand in NMEA–0183 (IEC 61162–1 Ed. 4)– or IEC
61162–1 Ed. 5–compatible format via rear–panel serial interface connectors for use in
shore–based applications, and is protected against a system reset.
・
An easy–to–use menu system is incorporated to set the transducer draft, depth
reference, echo threshold level, echo display mode, etc. in addition to operating
parameters to be selected mainly at installation time. Unauthorized access to the menu
system can be prevented with a user–definable password, if desired.
・
For use with the CVR–010 , BSH–approved highly energy–efficient single–element
TOKIN 50 and 200 kHz ceramic transducers are available. The desired frequency
should be specified at the time of ordering so that a matched transceiver board is
installed in the display cabinet before shipping.
・
Both the receiver gain and TVG (anti–clutter) levels are automatically controlled for
hands–free operation when the equipment is operating in the fully automatic mode
(
AUTO ). Manual override of both functions is also possible.
・
Possible interference from other echo sounders operating in the vicinity can be
effectively eliminated or reduced with a 3–step noise reduction function.
