The relative compression test is a quick-and-dirty way to check compression in an engine. Unlike a traditional compression test, this test doesn’t actually measure the pressure within each cylinder. . Being able to . Now that current clamps (amp clamps) and oscilloscopes (scopes) have become so cheap, it is possible to perform a lot of electrical diagnostics which were previously not (easily) available to the DIYer. In this post, I show results of a relative compression test on a 2007 4CYL accord using a current clamp that is regularly available for about .

Justin Miller demonstrating how to perform a Relative Compression test without an amp clamp. ***EPISODE 1*** https://youtu.be/il9iR095teMThis video is episode number 2 of 6 in a mini series involving a case study of a P0016 problem on a 2007 Toyota 4.The wide range of this clamp allows currents to be measured from under 1 amp right up to 2000 amps. It can therefore be used with a PicoScope (and other scopes) for many applications including: - Battery testing with PicoDiagnostics software - Relative compression testing - Starter motor testing - Alternator output testing
Any two channel scope will work for the test I’m going to show in my video. All scopes work by plotting voltage over time. There isn’t anything special about. Free Online Training & PicoScope Waveform Library: https://www.mechanicmindset.com/free-access?link=285&el=ytHow to perform a relative compression test with . Especially since the main reason i need one is for relative compression tests , but I've seen multiple sources use a low current probe for this. Nah, you made the right call. I used an AESWave low amp probe to do relative compression for many years. It worked, but there were always hassles. Many engines exceeded the 200A max of the probe.
The compression test is meant to be the first check. If the compression looks good, you can quickly move on to investigate other potential causes. If the tes.

Relative compression test using the Snap-On Verus. You do not need a Snap-on scope to do these tests. The same procedure can be followed using any Lab Scope. How to using a snap on lab scope and snap on amp clamp. This can be done with any lab scope and amp clamp.
Understanding the Relative Compression Analysis
Tech Tips Relative compression testing made easy
Test 1: Relative Compression. The purpose of the Relative Compression test is to examine and compare engine cylinder condition by observing the electrical current being drawn by the starter motor during engine cranking. . Connect the high-amp (2 kA) clamp to PicoScope Channel A; If you are using a BNC clamp, select the highest range and zero . Figure I need a high amp clamp to do relative compression test but concerned I won't be able to read small currents with a high amp clamp? Can I use a low amp clamp with a 20:1 attenuator for relative compression? Going to get one of the Hantek ones as they're cheap but open to others if there is justification for it. Just DIY guy so I don't . 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.
Plug the BNC connection of the high-amp current clamp into Channel A of the scope. Connect the current clamp around the battery cable . If a relative compression waveform highlights a problem, it will be necessary to perform a compression test. . A typical compression is between 120 and 200 psi. A low compression can be caused by: Quick test doing a relative compression test using the snap_on scope at the data link connector. Remember when doing this, if your waveform is not inverted then the compression will be the valleys and not the peaks like doing the same test with an amp clamp around the battery cables.
Will a 400a amp clamp be sufficient for a relative compression test or do you have to use a 600a amp clamp? I use a Pico 200/2000 amp clamp set at the 2000 amp setting but 400 amps should be good.if you are using a labscope you can use your AC setting set on a 1 or 2 amp scale and connect to your battery and read relative compression.how to set up the scope and amp clampemail at [email protected]
