why NI 9219 2 wire or 4 wire connection always give 10.5K for a 100 ohms resistor

Hello, 

I tried to measure resistance with a ni 9219 multifunctional DAQ.

 

However it always gives 10.K reading for a 100ohms resistor, irrespective of using the two wire or 4 wire configuration.

I am sure that the wiring is correct, and the resistor's resistance can be measured with a fluke 175 multimeter and Keithley DMM with no problem.

 

Any idea what is the problem?

 

Thank you!

I used NI MAX for the test.

 

I had no problem measuring temperature using the DAQ with a K type thermocouple.

It looks like 10kOhms is the range of the 9219.  So if you are reading the 10kOhms, you have an open somewhere.  Therefore it looks like you have it wired wrong.

Thank you for your reply.

 

I deleted all devices from NIMAX and restarted and the problem was resolved.

 

There was no problem with the wiring.
