4 wire resistance measurement using Compact DAQ - How to connect?

[nripen]

Sir

Is it possible to use DAQ Assistant for cRIO-9025 with NI 9219.

If possible please reply with the steps to be followed. I m using Measurement & Automation explorer of version 5.3.1fo.

I have a NI9219 in Compact DAQ 4slots USB and i want to measure a PT1000 in 4-wire resistance mode.

It works in 2-wire resistance mode correctly, but in 4-wire mode it shows always 10.5 k!

The used test wiring is only 50 cm long. The real wiring lengh should be about 50 m.

So what can I do? What is wrong?

I have no ideas anymore.
