4. VSFB and VSFSB: Using Internal Batteries
ECO meters with internal batteries can be powered in several ways.
1.
The meter can be powered from the six-pin bulkhead connector using the test cable (set to ON
BATT) or from an external source (test cable set to ON AUX). Communication is possible in
this mode.
2. Alternatively, the meter can be powered using a jumper plug in the three-socket bulkhead
connector. This is particularly useful for moored applications. The meter will run according to
its stored settings.
3. If the jumper plug is in place on the meter and supplying power and the test cable is
connected, power will be supplied by the equipment supplying the highest voltage. To
conserve the internal batteries, it is advisable to use the test cable and an external power
source set to 10–15 V.
4.1 Removing End Flange and Batteries
WARNING!
Changing the batteries will require opening the pressure housing of the ECO sensor. Only
people qualified to service underwater oceanographic instrumentation should perform
this procedure. If this procedure is performed improperly, it could result in catastrophic
instrument failure due to flooding or in personal injury or death due to abnormal internal
pressure as a result of flooding.

1. Make sure the instrument is thoroughly dry.
2. Remove the dummy plugs.
3. With connector end flange pointed downwards away from face, release seal vent plug.
4. Remove moisture from vent plug area.
5. Using needle nose pliers, remove filament from end flange.
6. Lift flange from pressure housing until seal is broken. The jacking screws provided with
sensor can be used to “push” the flange from the pressure housing and can then be
removed or left in the end flange.
7. Remove excess moisture from flange–can seal area.
8. Work the end flange out of the pressure housing and remove any residual moisture.
Remove the foam spacer and the neoprene insulator.
