Can I deploy my ADV6600 by attaching it to a metal pole or mount, or by putting it in a pipe
that is attached to a metal pole and still get accurate direction readings?
Ideally, the pole or mount should be non-ferrous/non-magnetic (i.e., aluminum, 316L stainless steel,
or plastic) such that it will have no effect on the compass readings. If a magnetic (ferrous) material
such as iron or steel pipe must be used, the ADV should be offset from the pole as much as possible
to minimize magnetic interference from the support. If at all possible, a compass calibration also
needs to be performed by rotating the entire ADV6600 and its mount so that compensation for the
ferrous material can be maximized.
Does the ADV6600 have to be deployed vertically, or can it be placed on its side for a
deployment?
The ADV6600 must be deployed vertically with the ADV sensor in the “down” position.
Do I need to clean or wash the ADV sensor before deployment?
It is good practice to clean the ADV sensor with water to remove any material that may have
collected on either the transmitter or receivers. A Beam Check test will indicate whether cleaning of
the ADV sensor is absolutely necessary.
After starting a logging study, can I calibrate sensors without stopping the study?
No. Unlike YSI 6-series products, the ADV6600 firmware automatically stops a logging study when
interaction is established via a computer running ADVantage 6600 software. In practical terms, this
means that all calibration must take place before starting a logging study.
D-4. Applications
For what applications can I use an ADV6600?
In general, the ADV6600 is designed for use in two types of applications:
1. Monitoring of current (water speed and direction) and water quality parameters with the
instrument powered by batteries or a data collection platform with no user present.
