I am using NI USB 6009 and analog input to get the temperature using thermistor. I have a small voltage division circuit with the thermistor and a 1k resistor.
When I am not connecting the Vout to the analog input I have 4.3V on it, but when I connect it to the DAQ pin, then my voltage drops to .37V. Does anybody know what could be the problem?
Thanks.
