c.
Unscrew the cap from the sensor storage bottle to relieve tension on the
o-ring and then remove the bottle. Replace the cap on the storage
bottle with the full cap that came with the new sensor to prevent
spilling the storage solution. Pat the sensor dry with a kim wipe
moistened with water to dissolve any deposits.
d.
Push the sensor into the connector on the cable until it is properly
seated and only one o-ring is visible. Failure to properly seat the probe
may result in damage.
e.
Twist the sensor clockwise to engage threads and finger tighten. Do not
use a tool. This connection is waterproof. Refer to the sensor
installation sheet included with each sensor for detailed instructions.
6.
Install the 2003 DO sensor in the DO port as follows:
a.
If an old sensor is installed, remove it by twisting counter-clockwise.
b.
Apply a dab of grease to the new sensor o-rings.
c.
Grasp the sensor with one hand and the sensor connection end of the
cable (bulkhead) in the other.
d.
Push the sensor into the connector on the cable until it is properly
seated and only one o-ring is visible. Failure to properly seat the probe
may result in damage.
e.
Twist the sensor clockwise to engage threads and finger tighten. Do not
use a tool. This connection is waterproof. Refer to the sensor
installation sheet included with each sensor for detailed instructions.
7.
Install the 2003 DO sensor membrane as follows:
a.
Change membrane and oxygen probe electrolyte solution every 30
days.
b.
Remove the metal sensor guard.
3.
If installing a membrane for the first time, remove the protective cap or
remove the old membrane cap by unscrewing it with the probe upside
down.
c.
Examine the gold cathode at the tip of the sensor and silver anode along
the shaft of the sensor. If either the silver anode is black in color or the
gold cathode is dull (tarnished), the sensor needs maintenance or
replacement. Refer to the Pro20 Instruction Manual, GENERAL
MAINTENANCE, of polarographic sensor (Model # 605203).
d.
Rinse the sensor with de-ionized water.
e.
Fill a new membrane cap (5908 Kit - Yellow, 1.25 mil polyethylene)
with oxygen probe electrolyte Solution. Do not touch the membrane
surface.
f.
Tap the side of the membrane cap to release air bubbles.
g.
Thread the membrane cap onto the sensor with the probe upside down.
h.
Replace the metal sensor guard.
D.
Cable Attachment
1.
Align the keys in the cable connector to the slots in the meter connector.
2.
Push together and twist the outer ring clockwise until it locks into place.
3.
To remove the cable, twist the outer ring until keys and slots are aligned and
