NI MUX 2575 CH24 closed R>3Ohm

[kdCMC]

Hey,

we have a NI MUX2575 where CH24 shows an extra 3 Ohm (or more) when closed.

Is this out of spec? Should I launch a SR (Service Request)?

thx,

Koen.

As per the spec sheet, anything above 1 ohm is a relay at the end of life.

Looks like you need to replace the relays to get them upto specifications,
