CarScope i-Tester is essentially a specialized type of engine analyser. It is a complex, multi-function tool, which can help diagnosing the engine and finding engine problems. I-Tester could be used with both gasoline and diesel-powered vehicles. Currently, its main mode is a relative compression testing but several automated diagnostic tests are upcoming with a future firmware updates!hgfh
No oscilloscope knowledge skills needed. You can skip the training and set-up time of an ordinary oscilloscope and get directly to a quick, precise engine analysis;
Relative compression test
This test is only a comparison between cylinders so we can use this method to "see" if we have a cylinder (s) with low compression by comparing one cylinder to the next. Hence the term "relative".
Relative compression is the fastest, simplest way to find a low compression cylinder. This test has previously been available only on large and expensive diagnostic systems, requiring a laptop and an oscilloscope. Now it is easier than ever — with the new CarScope i-Tester that combines bothfunctions - relative compression test and automatic waveform analysis. So, the final results are displayed in an easy to understand format.
You do not have to check each individual cylinder, all cylinders can be tested in one go. CarScope i-Tester works on 3, 4, 5, 6, 8, 10, 12-cylinder cars, 4 stroke, diesel and gasoline engines, DIS, conventional and Coil-on-Plug systems, and 12V electrical systems.
Cylinder synchronization
By hooking up a second probe to either the ignition or an injector, you can follow the firing order/injection sequence and know which one it is. This is not the only way to do this type of cylinder identification but it does work as a way to start with.
Common Rail pressure test NEW!
This new function is available since firmware version TT0106B (download link)!
This mode is used for fast verification of the condition of the diesel Common Rail high-pressure system.
Results allow direct/indirect identification of common problems in this system – lack of pressure due to leaks,
high-pressure pump failure, bad high-pressure sensor, no sensor power supply etc.
The principle of this test is based on checking the high-pressure sensor readings while the car is in ignition on,
cranking, idling and accelerating states.
Checking the high-pressure sensor readings is the fastest, simplest way to find a problem in the Common Rail system.
This test is very easy to perform – only one wire hooked to the high-pressure sensor output.
