Section 2.0 Membrane Cap Removal, Filling With Electrolyte
Filling membrane cap with electrolyte
5.
To avoid forming bubbles do not shake the electrolyte. Make sure the vent
hole is open. Tilt the electrolyte bottle as shown to minimize bubbles and fill
the membrane cap up to the brim with electrolyte, if needed tap to eliminate
bubbles.
Do not cover the vent hole with a finger when installing the membrane cap to
prevent electrolyte from leaking, doing so will create excessive pressure that will
destroy the membrane.
6.
Holding the shaft of the sensor vertically (do not hold the
membrane cap by covering the vent hole), slowly screw on
the filled membrane cap. You will feel resistance when the
cap reaches the O-ring, continue tightening until the cap
touches the electrode shaft. Excess electrolyte will overflow
from the cap, and when almost completely tightened it will
escape from the open vent hole. Be sure the cap is
screwed on tightly against the sensor shaft.
