New and updated Guided tests in PicoScope Automotive

GT021 Knock sensor

The test has been updated to use a higher impedance measurement probe (x10 probe). The update ensures test compatibility across a wider range of sensor types: i.e. some knock sensor signals are distorted by lower impedance measurement probes.

GT032 Fuel pump motor (brushed)

As well as a general refresh, this update includes a more in-depth description of DC brushed motors. This helps users to understand their possible failure modes and how they related to possible symptoms.

GT783 Parasitic battery drain (clamp method)

As well as a general refresh, the test steps have been made clearer and more information has been provided to help with the diagnosis of parasitic battery drain faults.

NEW: GT875 DPF back pressure

This new guided test describes how to measure Diesel Particulate Filter (DPF) backpressure and interpret the results.
