The Hickok Auto Wave signal waveform viewer, No. 75000, allows users to quickly and easily verify that signals and voltages are present in waveform format using a voltage/time scale on the color LCD screen. Users can view primary ignition, fuel injectors, throttle position sensors, drive-by-wire components and more. The auto-set feature automatically sets the voltage and time scales, which simplifies viewing detailed waveforms for users who are getting started with waveform diagnostics. Auto Wave has a sample rate up to a million samples/second and waveform snapshots can be saved to a 4GB SD card.
