Section 6. Using Your ADV6600 In The Field
After setting up your ADV6600, calibrating the sensors, and determining how the instrument will be
mounted at the site of interest as described in the previous sections, the sonde is ready for use in the
field. Detailed instructions for three types of field use (real-time, deployment with logging to
internal memory, and deployment with logging to a data collection platform) are found below.
Before moving to the field, you are also advised to consult Appendix D which answers questions
frequently asked by first-time users of the ADV6600 and Appendix G which provides setup
instructions in a quick-start format.
6-1. Checking Your Battery Voltage
No matter which mode of operation is relevant to your application, prior to taking the instrument to
the field you should assure that the batteries in your sonde are either new (recommended) or have
sufficient remaining capacity to handle a specific short term application (based on your empirical
experience with correlating battery capacity with voltage). To make sure that your batteries have
the power to suit your field needs, make sure that you check the voltage prior to any deployment
using the Check Battery Voltage selection in the Tools and Utilities list as shown below
The battery life is a function of two major factors – the sample interval and the averaging interval.
The instrument specification for battery life is approximately 30 days at a 15 minute sampling
interval and a 1 minute averaging interval. An increase in the sample interval will improve the
battery life; for example, you will get approximately 50 days at a sample interval of 30 minutes
while maintaining an averaging interval of 1 minute. Conversely, an increase in averaging interval
(perhaps to increase data smoothing) will result in a lower battery life – approximately 15 days with
a 2 minute averaging interval while maintaining a 15 minute sample interval. Using these rough
examples, users could estimate, for example, that the battery life with a 30 minute sample interval
and 2 minute averaging interval would be about 25 days
Note, however, that the estimation of battery life is somewhat inaccurate and may vary slightly from
instrument to instrument. Therefore, as stated above, it is always best to use new batteries for each
deployment if possible.
