Membrane Cap Assembly - Filling and Replacement
The electrode is shipped dry and requires f lling with the supplied electrolyte
solution before the f rst use. The membrane should be in place and does not need
to be replaced.
Important Note
: Do not touch the membrane as skin oils will interfere with the
oxygen permeability rate of the membrane.
1. The electrode should remain attached to the meter during the process.
2. Carefully remove the membrane cap assembly from the electrode by
f rmly unscrewing it in a counter-clockwise direction.
3. Discard the used membrane cap assembly.
NOTE: When a membrane cap is installed the membrane must tightly
stretch over the cathode. If a membrane cap is removed, it can not be
reinstalled because the membrane will no longer stretch properly over
the cathode.
4. Rinse the cathode and anode with deionized water.
5. Set the membrane cap assembly on a f at surface.
6. Fill the membrane cap assembly with Electrolyte Solution (DO600-EL) to
the bottom of the threads on the inside of the cap. To remove air bubbles
hold the cap steady with one hand and tap the side of the assembly
sharply with a pen.
