Sensor comparison

[Funchion]

hi

I am using the ni daq usb 6008 to measure two inductive sensors waves. I have no problem getting data from one sensor but when i try to make a comparison with the second sensor it wont work. the error reads you have connected two terminals of different types,the type of source is dynamic data and the type of sink is double.

also with the two sensors connected to the same daq card to i need two daq assistants in labview or just one. please find attached screen shot of troublesome program.

Two DAQ assistants won't work because they're trying to use the same resource (hardware) at the same time.  A properly configured single DAQ assistant whould work.

Try changing the dynamic type to something else before the comparisons (see attached).
