Section 2. Preparing the System for Field Studies
Before using your ADV6600 in field studies to correlate water movement with water quality
parameters, you will need to prepare the dissolved oxygen sensor for use, install the water quality
probes into their proper ports, supply a power source, and attach a cable between the ADV6600 and
your PC. This section provides detailed instructions for this setup procedure.
2-1. Preparing the Dissolved Oxygen Probe
The DO probe is shipped with a dry, protective membrane secured by an o-ring. This membrane
requires replacement before initial use of the sonde. Subsequent membrane changes should be
performed before each deployment of the sonde and at least once every 30 days during sampling
applications, or more frequently as needed.
Initial DO membrane installation can be performed before the 6562 DO probe is installed in the
sonde. However, after installation of the probe, it is recommended that removal of the probe from
the body of the ADV6600 be limited and future membrane changes should be performed while the
probe is installed.
WARNING! Wash hands before installation and do not allow finger oils or O-ring lubricant to
touch the probe face or the membrane.
2-1.1. Preparation of the DO Electrolyte Solution
Unpack the 6562 DO Probe Kit. Locate the 5775 DO
Membrane Kit and prepare the electrolyte solution.
Dissolve the KCl (Potassium Chloride) in the dropper
bottle by filling it to the neck with deionized or distilled
water and shaking until the solids are fully dissolved.
After the KCl is dissolved, wait a few minutes until the
solution is free of bubbles before using.
2-1.2. Membrane Installation without the DO Probe Installed in the
Sonde
• Remove the protective cap and the dry membrane from the YSI 6562 DO Probe. Handle the
probe with care to prevent the sensor tip from becoming scratched or contaminated.
• Leave the protective cap in place over the connector end of the probe to prevent contamination
by the electrolyte.
