The HT201 has been designed to allow fuel injector and primary ignition waveforms to be measured using Hantek oscilloscope products..
Please note this attenuator should not be used for any high voltage measurements other than fuel injectors and primary ignition..
Passive attenuator with 20:1 attenuation, if input a 20V signal, it can output a 1V signal.Because the signal is attenuated, by using this item, oscilloscope can measure voltage higher than its range(±20V).
【What you will get】 1 x HT201 Signal Attenuation.
