The attentuator is a passive 20:1 attenuator. This means that a 20V signal at its input will appear as a 1V signal on the output. As the signal is attenuated, the attentuatorallows voltages higher than the Â±20 V input range of the Pico oscilloscope to be measured (see the safety precautions below).
The attenuator, when used with Pico PC oscilloscopes provides increased input protection against overloads when working with inductive signals such as injectors and primary ignition. Under no circumstances attempt to use this attenuator to measure secondary ignition (HT) waveforms, the 16 162 106Secondary Ignition Pickup lead should be used for this purpose.
Attention: Only for automotive applications. Not for use with 230 V applications!
The attenuator has been designed to allow fuel injector and primary ignition waveforms to be measured using Pico oscilloscope products..
