If necessary, wipe the membrane with a cloth.

Attach the new textile mesh under slight tension to the Velcro tape.
Press it on the opposite sides of the Velcro tape. To avoid wrinkling, pull the
textile mesh as evenly as possible.
Make sure that the textile mesh does not protrude from either side of the Velcro tape
and the function of the chamber sealing is not impaired.

During a measurement, two mesh-protected membranes nestle from the top and from
the bottom in the test object due to the pumping action.
The membranes may be leaking, so that accurate measurements are no longer
possible. Causes of damage can be sharp edged objects, aging or wear. Remove the
membrane support including the damaged membrane.
If you want a repair, please send the diaphragm carrier with membrane to the
manufacturer. Due to the high quality requirements at the manufacturer, the
membrane support is re-tensioned, the components are tested and then a leak testing
is performed.
Dismantling the
membrane support
ü
At least one membrane no longer functions properly or has to be replaced for
reasons of age.
1
Open the measuring chamber and determine which membrane is damaged.
For this you can remove the mesh, see "Cleaning the membrane [
49]”.
2
If it is necessary to remove the upper membrane support including the damaged
membrane, unscrew the 16 screws with a T25-TORX® screwdriver.
