Features Allows the oscilloscope to measure the injector and primary ignition waveforms. Specifically designed to assist in automotive measurements. 20:1 attenuation passive attenuator, input 20V signal, can output 1V signal. Since the signal is attenuated, using this project, the oscilloscope can measure voltages above its range (±20V). It provides enhanced input overload protection when used in oscilloscopes to measure inductive signals. Do not use it for secondary ignition tests.
