Internal Battery Pack; Optional Rechargeable Battery Pack - idronaut Ocean Seven 304Plus Operator's Manual

INTERNAL BATTERY PACK

The OCEAN SEVEN 304Plus CTD housing has, in its upper part enough space
to accommodate an internal battery pack.
The OS304Plus is powered by a single 3.6V battery or two Alkaline 1.5V
batteries; different types of battery can be installed in the CTD housing.
Together with the CTD, IDRONAUT ships two plastic battery holders for the
single Lithium or the double Alkaline batteries.
IDRONAUT does not include the batteries in the CTD shipment.
 2 x size "AA"Alkaline 1.5V battery assembled in a single pack
 1 x size "AA"Lithium non rechargeable battery
 1 x size "C" Lithium non rechargeable battery
 1 x size "D" Lithium non rechargeable battery
 NiMH IDRONAUT rechargeable custom battery pack (3x1.2 AA)
INSTALLING TWO 3.6V LITHIUM BATTERY IN THE DOUBLE ALKALINE BATTERY HOLDER
AND CONNECTING IT TO THE OS304Plus TOP COVER WILL CAUSE A PERMANENT
DAMAGE TO THE OS304Plus CTD ELECTRONICS.
When the CTD is not used for long periods (e.g. 2 weeks or more), we suggest disconnecting the
internal battery pack connector from the CTD electronics or removing the internal battery pack from
the CTD to prevent the internal batteries from damaging the CTD due to battery acid leakage. This is
why the OCEAN SEVEN 304Plus CTD is shipped without batteries installed. The status of the internal
battery pack can be derived from the battery diagnostic reading on the CTD start-up message.

1.7.1. Optional rechargeable battery pack

An NiMH IDRONAUT custom rechargeable battery pack (3.6VDC,
2.6Ah) is available upon request. It comes complete with an international
battery charger. Please be aware that it is not possible to recharge the
batteries when they are installed inside the CTD. Therefore, the CTD top
cover must be opened to recharge the internal NiMH battery pack.

These programs interfaces the OS304Plus CTD and allows the
operator to dialogue directly with it thus performing: sensor
calibration, real-time data acquisition, CTD configuration, etc.
All these operations are possible thanks to the CTD smartness
included in the management firmware.
Furthermore, the "Portable Reader" not only shows data sent by
the CTD in real time but also stores it.
Data is stored in files using the "Portable Reader" main or
extension "Flash" memory which can be later transferred to a
desktop personal computer using the Microsoft ActiveSync
program.
Data acquired by means of the "µREDAS" program must be
imported using the REDAS-5 program.
Data storage capability of the "Portable Reader" is limited only
by the size of the installed "Flash" memory card.
The "Portable Reader" can operate for up to 15 hours
continuously. Autonomy of the interfaced CTD is about 40
hours.
