I currently have a UniMeasure Linear Potetiometer which has a 50" cord length and a senstivity of 19.54 mV/V/Inch. The voltage that is supplied is 10V and the impedence is 1000ohms.
I am supplying the voltage excitation via the NI 9237 and trying to read the voltage via an analog input on NI 9215. But when I attach a voltmeter to the same hook up I am not reading the correct voltage on the waveform chart.
Then I need to convert the voltage to mm to display length of the cord extended.
