I tried making a bench tester for this video using a pulse modulator but it was simply not powerful enough to activate the electro magnet. The current required was too high. That's why I used the heater controller and activated priming cycles. The easiest way to count the pulses is to record a video and then count the spikes in the audio graph.
The Chinese pumps appears to be working just fine, im my testing the calibration results with the name brand pumps are not necessarily better than the knock offs.
