Passive Attenuator, 1.053M Input Res HT201 Converter Passive Attenuator 20:1 Passive Oscilloscope Signal Attenuator for Inductive Signal Primary Ignition, Automotive Diagnostics Use

• 20:1 OSCILLOSCOPE PASSIVE ATTENUATOR: Can be used with most oscilloscopes to measure injector and primary ignition waveforms. Note that this attenuator should not be used for any high pressure measurements other than injectors and primary igniters.
• PASSIVE 20:1 ATTENUATOR: If input 20V signal, it can output 1V signal. Since the signal is attenuated, using this project, the oscilloscope can measure voltages above its range (±20V).
• MEASUREMENT RANGE: Due to signal attenuation, using this item, the HT201 attenuator can measure voltages above its range (±20V).
• PRODUCT FEATURES: It provides enhanced input overload protection when used in oscilloscopes to measure inductive signals, such as nozzles and primary ignition. Do not use it for secondary ignition tests.
• AFTER SALES & SERVICE: If for some reason you are not satisfied with your purchase, damaged, damaged in shipping or even changed your mind. Please feel free to contact us, we will be happy to answer your questions.
