CarScope i-Tester Portable Engine Test Tool

i-testerCarScope 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!

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.

Important note: Because of lithium-ion battery shipping restrictions, we do not include CR2032 lithium-ion battery inside in the post packages! When you receive the tester, you have to buy a Li-Ion battery type CR2032 yourself and put it into battery holder socket inside the CarScope i-Tester. To do so, you should unscrew and remove four screws to open the bottom cover. We apologize for the inconvenience!

Advantages
  •  Non-invasive test;
  •  Test completes within seconds;
  •  You do not need a pressure transducer to run the relative compression test;
  •  No mechanical work needed. No removal of spark plugs, glow plugs, or injectors, thus preventing accidental damage to the customer’s engine components. All you have to do is to disable the fuel system to prevent the engine from starting;
  •  Disabling fuel system is always better because you are not flooding your cylinders;
  •  No oscilloscope needed;
  •  Reduced skill level required and thus achieve rapid testing;
  •  No waveform analysis skills needed;
  •  Test based on scientifically grounded theory;
  •  Test proven in the practice for many years;
  •  Useful tool in the parking lot type situation instead of dragging a scope/laptop around;
  •  No current clamp needed, in case the DC voltage method is used
