DAQmx problem in voltage measurement

[perumpadapu]

I had installed DAQmx. I 'am using a DAQ (NI USB 6009). When I'am trying to measure, the channels show error values i put it in RSE mode with continous sampling,samples 100 1000hz. Please kindly reply to me.

Just to clarify... is it the data values that are different to what you expect or are you actually getting errors when you try to run the code?

What are you getting and what are you expecting? Or what error code is coming out?

Perhaps you could upload your VI.

ts not rror, the values are not correct. that 's the problemi

In RSE mode you must connect AI GND to the measurement source ground.

Also make sure your signal doesn't exceed the input max/min (+/-10V).

The device may protect itself by disabling the inputs. Unplug it and plug it back in to reset.
