Introduction; Instrument Overview - AML Oceanographic AML-6 RT User Manual

1 Introduction

The AML-6 series of instruments is a highly configurable family of multiparameter sondes
designed for a wide range of data collection applications. The '6' designation refers to the
number of sensors that may be simultaneously installed on the instrument endcap. Additional
sensors may be connected externally, allowing up to 8 sensors in total.
There are two primary configurations of instruments in the AML-6 family: the AML-6 LGR, a
self-powered instrument designed for profiling applications, and the AML-6 RT, an externally
powered instrument intended for Real Time applications. While nearly identical in size and form
factor, the two configurations differ in a few key features which specialize them for their
respective applications.
Instruments with the LGR designation (ie. AML-6 LGR) are self-powered via a rechargeable
internal battery and have a mechanical on/off switch adjacent to their shackle. These
instruments are designed to internally log sensor measurements and transfer data
post-deployment. These instruments are most commonly used for multiparameter profiling.
Real-Time instruments, in contrast, are designed to stream data while in-situ (though they have
the ability to internally record data as well). Both power and communication to these instruments
is facilitated via a waterproof connector located adjacent to the shackle. These instruments rely
on external power for operation and the application of this power turns the instrument on in lieu
of a mechanical switch These instruments are commonly used in moored applications, buoys,
underwater observatories, and ROVs.
This manual describes the operation of the Real-Time version, the AML-6 RT.

1.1 Instrument Overview

AML-6 instruments are highly customizable and so may be equipped with a wide range of
user-specific sensors, functionality, and features. The instrument described here is intended to
be a representative example of a typical setup and therefore may not be identical to the
Reader's. The Reader is directed to any unit-specific supplementary documentation provided
with their instrument for information on features and functionality not described here.
