Hello, I have the same problem as this.. except I already have 2 encoders (for the two shaft speeds I am measuring)... one with an output pulse of 8V, another of 3V. When I input these on my analog input, my frequency is all over the map (not accurate at all).. I am using DAQ assistant for voltage input and timing wizard (the one in express) to output frequency. When I connect a graph to my input, I clearly see the pulses and spacing so I don't understand how the frequency reader dosen't work. Any ideas? My input looks like: ____|____|____|____|____ ... For every revolution theres a pulse. Thanks -Jon
