The graphs are reversed actually, the time axis is scrolling from left to right, the right side, with the higher number, is further into the past. A quirk of the program.
I have been trying to come up with a way to incorporate a tachometer/frequency counter into this DAQ, a clean solution is eluding me at this point. So sorry, no fan speed readings. (and no flowmeter readings, but I am trusting the delta T flow rate calculation more and more). Duty cycle, I cannot sample better than 1ms, the PWM frequency is above this, some component value changes might fix this if I find it necessary.
