ADVField/Hydra Operation Manual (September 1, 2001) 65
The power switch on the front panel will disconnect the ADV from any external supply and from
the internal rechargeable battery. Make sure this switch is off (the diode on the front panel is lit if
the switch is on and the ADV has input power) when not being used to prevent draining the re-
chargeable battery. The switch does not affect the connection between the rear-panel battery
charger input and the internal battery.
Accessing the processing module for systems with the rechargeable battery is done using the
same procedure given in §4.4. The only difference in internal wiring is a connector from the front
panel wiring over the top of the Analog board. This connector mates with a connector from the
rear panel and battery, and should be disconnected while removing the ADVField electronics.
4.6. Accessing the Signal Conditioning Module
The ADV signal-conditioning module contains the receiver electronics and any optional sensors
(compass/tilt, pressure, and temperature). It should not need to be accessed during normal opera-
tion. The only common reason is to change the orientation of the internal compass/tilt sensor or
to change probes (16-MHz or 10-MHz ADV without optional sensors only).
16-MHz MicroADV or 10-MHz ADV without Optional Sensors
The conditioning module for the 16/10-MHz ADV systems without optional sensors is a cylinder
with dimensions of 6.4 cm (2.5 in) in diameter by 28.5 cm (11.2 in) long. The probe is mounted
from the bottom end cap; the end cap is an integral part of the probe assembly. The high-
frequency cable from the processing module is connected to the top end cap using a non-
removable penetrator. The receiver electronics are directly mounted to the top end cap / cable as-
sembly, and are connected to the probe end cap using an edge connector on the receiver board.
5 MHz-ADVOcean without Optional Sensors
The conditioning module of the ADVOcean without optional sensors should not need to be ac-
cessed under normal operating conditions; instructions are not provided in this manual. If you
have questions about the ADVOcean probe, or think you need to access the conditioning module,
please contact SonTek.
16-MHz MicroADV or 10-MHz ADV or 5-MHz ADVOcean with Optional Sensors
For the 16/10/5-MHz ADV system probe with compass/tilt sensor, you may need to access the
conditioning module to change compass orientation. (See §4.7.2 for details on internal compass
mounting for different probe orientations.) To access the conditioning module, only the connec-
tor end cap needs to be removed.
You should not remove the sensor end cap on which the acoustic sensors are mounted. The re-
ceiver electronics are mounted directly to this end cap, and the alignment of the end cap with re-
spect to the housing is set at the factory. Instructions for removing the sensor end cap are not
provided in this manual; if you think you need to remove this end cap, please contact SonTek.
The connector end cap is secured to the housing by three #6-32 screws. To access the condition-
ing module, remove these screws using the screwdriver provided in the ADV tool kit. Lift the
end cap directly out from the housing. The compass/tilt sensor and the pressure/temperature sen-
sor board are mounted directly to the end cap as described in §4.7.2. When removing the end cap,
