• Roll the o-ring over the end of the probe, being careful not to touch the membrane surface with
your fingers. There should be no wrinkles or air bubbles. If any are present, remove the
membrane and repeat the installation procedure with a new membrane. Squeeze the o-ring
every 90 degrees to equalize the tension. Do not use grease or lubricant of any kind on the o-
ring.
• Trim off any excess membrane with a sharp knife, a scalpel, or scissors. Make the cut about
1/8-inch below the o-ring. Rinse off any excess KCl solution.
• Use caution when replacing the probe guard that you do not touch the membrane. If you
suspect that the membrane has been damaged, replace it immediately.
2-2. Installing Water Quality Probes
Remove the calibration/transport cup from your ADV6600 by hand to expose the bulkhead.
Note: The ADV probe is a non-removable sensor.
2-2.1. Removing the Port Plugs
Using the long extended end of the probe installation tool supplied in the YSI 6570 Maintenance
Kit, remove the port plugs by unscrewing them from the bulkhead of the sonde. Save all the port
plugs for possible future use. If the provided tool is misplaced or lost, you may use 7/64” and 9/64”
hex keys as substitutes.
NOTE: You may need pliers to remove the ISE port plugs, but do not use pliers to tighten the ISE
probes.
Hand-tighten only.
