Hello Everyone,
We have two machine (9.1B) that are failing the leak test in TSM. My colleague and I changed the membranes on those machine to fix the issue. However we are getting the same issue. The machine I worked the test fails when doing negative pressure test. The PDA sensor goes from -403 to -380. I'm wondering if we installed the membranes properly. Is there a way to confirm the membrane leak with a external monometer? Or if its not membrane what are the likely issue that could be causing it.
Those machine don't have any error code during self test and UF measure is also fine during sim therapy
Thank you

<larin218> You should have the newest Dialog service manual Revision 1.02.00. In this version, as part of the PM, there are manual leakage tests that can be performed using clamps, a container of water and the acid pump to build up both positive and negative pressure. In this way, once the circuit is pressurized, you can then manually clamp off sections to determine when the leak stops and then investigate that area.
