TC-2095 sockets not working

[chs87]

Several sockets on my TC-2095 card are not working.  I can get some of them to work by moving the plugs around until it achieves contact with the socket connectors.  I assume that there is a method to "tighten" the sockets to achieve reliable connections when inseting a thermocouple plug.  Can you provide instructions on how to fix this problem?

Actually, there is not a way to tighten the thermocouple miniconnectors on the TC-2095.  I just took one apart to verify, but the thermocouple miniconnectors are each independent and are closed.  How tightly a thermocouple is held is determined by how tightly the copper connectors inside are pressed against it.  There is no way to tighten those copper connectors such that they press down tightly again.  The individual thermocouple miniconnectors cannot be opened and modified.

If your TC-2095 is old, this was most likely caused by repeated wear on the copper, such that the copper does not spring back as tightly as before.  You could RMA the device noting that the connections are not holding thermocouples as tightly as it should.
