• Remove the old DO membrane and clean the probe tip with water and lens cleaning tissue.
Make sure to remove any debris or deposits from the O-ring groove. Handle the probe with
care to prevent the sensor tip from becoming scratched or contaminated.
• Apply a few drops of electrolyte solution to the tip of the probe. The fluid should completely
fill the small moat around the electrodes and form a meniscus on the tip of the sensor. Be sure
no air bubbles are visible. If necessary, shake off the electrolyte and start over.
• Hold the membrane so that all four corners are supported, but do not stretch the membrane
laterally. Always handle the membrane with care, touching it only at the ends.
• Position the membrane over the probe, keeping it parallel to the probe face.
• Using one continuous downward motion, stretch the membrane over the probe face. Do not
hesitate to stretch the membrane until it conforms to the face of the sensor.
