●Automotive Measurement Assistant: This product is specially designed to assist automotive measurements. It can help the oscilloscope measure fuel injectors and primary ignition waveforms. ●Passive attenuator: With an attenuation ratio of 20:1, it can attenuate the input 20V signal into a 1V output signal. Since the signal is attenuated, after using this product, ●Enhanced input overload protection: When used with an oscilloscope to measure inductive signals such as injection nozzles and primary ignition, it provides enhanced input overload protection. Do not use it for secondary ignition testing. ●High frequency response: With a bandwidth of 10MHz, it can meet higher frequency measurement needs. Whether it is measuring the injection nozzle or primary ignition waveform, it can provide accurate signal response. ●Compact and portable design: Measuring only 61 x 21 x 10mm, it is very compact and portable. You can carry it for measurement anytime and anywhere, which is convenient and practical.
