To mount a single membrane:
•Take a few membranes out of the storage box.
•Using tweezers included in the kit, pick up one membrane from the stack, and gently place it on the sensor tip.
•Make sure it is centered.
To mount dual membranes:
•Remove one 29562A secondary membrane along with one piece of the separation paper from its box. Place the membrane and paper, paper side down, on a clean flat surface.
•Remove a primary membrane along with its separation paper.
•With the separation paper on top of the primary membrane place the primary membrane directly over the secondary membrane, taking care to center the two membranes.
•Rub your finger on the paper of the primary membrane to remove any air bubbles between the membranes. The two membranes should now be sandwiched together and appear as one membrane.
•Pickup the sandwiched membranes with tweezers and remove the separation paper.
•Gently place them on the sensor tip ensuring the secondary membrane (29562A) is on the bottom.
•Make sure they are centered.
Note:
Distinguish the membrane from the protection paper:
-Membrane is transparent (translucent).
-Protection paper is opaque.
The membrane diameter is larger than the sensor head diameter. This is normal, as the membrane will fold over the sensor tip.
The membrane holding ring comes in two slightly different internal diameters, depending on the membrane(s) total thickness.
For a correct membrane installation, be sure to use the correct holding ring for the application.
If mounting dual membranes, always use mounting ring part number 29229.
