Yes, it can perform a relative compression test. There is a built in preset for relative compression using a high current amp probe.
Since the scope only has 1 channel, in order to identify a low cylinder you have to get creative but either taking a second waveform with a spark plug removed and using that low cylinder as a reference; or depending on how you disable the vehicle from starting, positioning an ignition wire near the amp clamp to will produce a spike in the waveform.
