If a relative compression waveform highlights a problem, it will be necessary to perform a compression test. When compression testing on a petrol engine, it is important to fully open the throttle to allow a larger quantity of air to pass into the cylinders. A typical compression is between 120 and 200 psi. A low compression can be caused by: For many years mechanics have been using labscopes and current clamps to view relative compression during engine cranking. A PicoScope oscilloscope when use.This is the lowest-cost option for a technician wanting a PicoScope system that you can just use ‘out of the box’. If you want to start with PicoScope, this kit allows you to benefit from a modern, high-performance labscope with PicoBNC+ test leads, and PicoScope 7 software while providing a great solution for those on a limited budget.

TEST 1: Relative Compression / Cranking 14 TEST 2: Battery, Alternator and Starting Test 15 TEST 3: Diesel injector current 16 . In addition, when you select the Guided Test, the PicoScope software also opens a data file which sets up the PicoScope to run the given test. This means that in your first days of using PicoScope you don’t have .Video Commentary. In this Compression Test animation, an exhaust valve on Cylinder 1 is not sealing properly (valve-stem bent).
