The CarScope i-Tester is essentially a specialised type of engine analyser. It is a complex, multi-function tool, which can help diagnosing the engine and finding engine problems. I-Tester can be used with both petrol and diesel-powered vehicles. Currently, its main mode is relative compression testing but several automated diagnostic tests are upcoming with 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 Ñ with the new CarScope i-Tester that combines both functions - 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 petrol 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. Optional cylinder trace / pickup ET0102-01

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

Applications
Reasons to perform a relative compression test using i-Tester:
Compression test has to be performed when the engine symptoms are as follows:
- engine misfiring;
- rough idle;
- loss of power over time;
- unexplained loss of power;
- smoke from the exhaust;
- puffing noise in induction or exhaust

2. Checking the engine health in cases as follows:
- In case of buying a used car;
- Before ECU remapping to evaluate engine status;
- Periodic prevention check;
- In cases where it is very hard to gain access to the spark plugs in order to perform a traditional compression test.

This inductive clamp is designed to clip onto the spark plug wire to cylinder one to get the trigger signal that is used to identify the correct cylinder number of each ignition voltage signal.

This clamp adaptor is a transducer which will allow your oscilloscope, motor tester or multimeter to measure electrical current up to 600 amperes, both types AC or DC, with a frequency response up to 400 Hz.

When measuring current with this clamp adapter, there is no need to break into the circuit or disturb the isolation as the opening jaws simply clamp around the current carrying conductor. No electrical contact is required.

• 30mm jaw opening
• 0 - 600A range (AC / DC)
• 0-600mV output (AC / DC)
• Supplied with 4mm banana plug type connectors. A separate BNC to 4mm adaptor may be required for some applications.

A specialised current clamp to allow your oscilloscope, multimeter to measure electrical current from 10mA up to 60A - both AC / DC - with a frequency response up to 20kHz.

This current clamp adaptor is ideal for displaying current waveforms for fuel injectors, fuel pumps, ignition coil circuits, and testing the solenoid valve for electronic diesel fuel injection control (EDC) systems.

The small measuring jaws allow the adaptor to be used in tight spaces.

• 4mm banana plug connectors
• Two calibration settings: 10mA - 20A AC / DC range & 20A - 60A AC / DC range
• 9mm max jaw opening
• 9V DC battery supplied with unit

Adds a Pressure Pulse sensor for engine health testing, 2x AC/DC clamp meters for current testing and doubles the ignition testing components to fully utilise both channels on the scope.

AutoSim allows a mechanic to simulate the replacement of a sensor.

Simulating output signals of most automotive sensors, AutoSim picks up service issues where a scan tool's diagnosis ends. Sensors tell the on-board computer when something is wrong. AutoSim helps determine if the cause is a faulty sensor, wiring or the ECU.

The product is mainly used for wiring tests. This is because the device can simulate the voltages and check the live data readings on the scan tool to confirm the wiring. You can simulate most sensors from ABS to O2 sensors. Eliminates need to replace non-defective sensors; by the time you have changed a couple of un-needed sensors the device has paid for itself!

• Voltage simulation range: 0.1V ~ 12V
• Frequency simulation range: 0.1Hz ~ 10KHz
• Trigger pulse output: up to 0.15 amperes maximum
• Output amplitude: 0.2V to 12V output amplitude can be selected at each mode
