3. From the package of membranes supplied with the sensor, place a new membrane into the
front nut.
The membrane is white in color and is separated from other membranes by a
light blue paper spacer.
4. Screw the front nut on to the chamber until you feel the o-ring compress. Hand tight
compression is all that is needed. Do not use tools to tighten. The membrane should be flat
across the bottom of the chamber without wrinkles.
5. Fill the chamber with electrolyte until the level reaches the bottom of the internal threads.
6. Slowly screw the chamber onto the sensor body. A small amount of electrolyte will run out of
the hole from which the vent screw was removed. Place a paper towel around the sensor to
absorb the electrolyte overflow. Use
EXTREME
Caution when handling electrolyte. Tighten
the chamber until the o-ring at the top of the chamber is compressed. Once again, do not
use tools to tighten.
7. Shake excess electrolyte from the fill hole on the side of the sensor and replace the vent
screw.
The sensor is now ready for operation. The membrane should be stretched tightly across the tip
of the sensor.
CAUTION:
When handling the assembled sensor, do not set the sensor on its tip or damage
to the membrane will result. Severe impacts on the tip of the sensor from dropping
or other misuse may cause permanent damage to the sensor.
