I wouldn't recommend either Hantek is the cheapest of the cheap lots of other DC clamps available. A low range clamp is a better first buy as without a high range clamp you can do relative compressions by scoping the voltage across the battery, the humps for each cylinder are just inverted ie a higher voltage hump = low compression cylinder.How to perform a compression test with a scope (Verus-Vantage): {youtube}WKdZsWU2ZmI|615|345|0{/youtube} Jumped timing chain (no compression on 3 cylinders) - GM 3.6: .

Good question! Voltage measurement is just fine for relative compression testing. Andy has gone over the set up in the past in the forum. Remember that voltage and current are Inversley proportional, so the valleys of the voltage waveform will be representative of the peaks of an amperage waveform.

After that, I swapped cylinder 1's coil and spark plug with another cylinder, and took it out for another test drive. During a WOT runup it began to misfire again (as indicated by the flashing MIL). The scan tool indicated that it was still on cylinder 1. Next, I did a quick compression test on cylinders 1 and 3.(Chapter 1) Misfire ID, Compression Test, Vacuum Leaks, Fuel Trim, Head Gasket, Restricted Exhaust, Low Power, DVOM (Chapter 2) Switch Inputs, digital signals, module communication, hall effect testing .

As part of the diagnostic procedure I have performed a relative compression test with a current clamp. On the waveform I notice that 3 and 3 bumps are offset a little bit compared to eachother and maybe differs a little bit in height.
Hi, recently watched SD video on carrying out compression tests using scope to ID faulty cylinder etc, I would like to know is there a diag tool/scope that gives ia readings in amps, I remember in the 80s we had a souriau diag machine that did this and we could print the results as diesels are a lot more complex to work on it made me think l maybe barking up the wrong tree . Disconnecting the crank sensor will work on all engines, others may not star with the cam sensors disabled. My all time favorite on cars with a chip in the key fob is to wrap this part in aluminum foil or hold a magnet close to it while cranking.
