Mechanic Reviews
I upgraded to this 8 channel automotive oscilloscope after struggling with a cheap Chinese import for years. The difference in software stability is night and day. The CAN bus decoding is brilliant and has already saved me hours of diagnostic time.
Ordered on a Tuesday, arrived Wednesday morning. The build quality is solid aluminium, not cheap plastic. Used it as a fuel injector oscilloscope on a tricky diesel transit van and found the timing fault within 10 minutes. Top piece of kit.
As an auto-electrician, I need reliable tools. The programmable generator feature on this scope is fantastic for simulating O2 sensor signals directly to the ECU. Highly recommend TestScope for their UK support too-they actually answer the phone!
Great car oscilloscope diagnostic tool overall. The waveforms are crisp and the 8 channels are great for complex timing checks (crank vs cam). My only minor gripe is that the included USB cable could be a bit longer for reaching into the cabin during road tests.
Far superior to the Hantek I used to own. The software doesn't crash, the 12-bit resolution makes a massive difference when looking at fine sensor noise, and the automotive presets are actually accurate out of the box.
Very capable vehicle signal oscilloscope. It took me a couple of days to get used to the software interface as I'm a beginner with scopes, but the built-in reference waveforms are a massive help. Good value for money.
Workshop Setup Guide
- Install the TestScope software onto your Windows PC or laptop using the provided USB drive or by downloading the latest version from our website.
- Connect the usb auto scope to your PC using the supplied heavy-duty USB cable. The device will power on automatically.
- Connect the BNC test leads to the desired channels and attach the appropriate probes (e.g., piercing probes or crocodile clips) to the vehicle's circuit.
- Open the software, select 'Automotive Diagnostics', and choose from over 80 presets (e.g., CAN Bus, Crankshaft Sensor, Injector Voltage) to automatically configure the timebase and voltage scales.
- Start the engine or cycle the ignition to capture and analyse the live waveform data.
