Oscilloscope
Allows displaying data on the screen simultaneously from analog channels in any combination, as well as the 9th synchronization channel in one of the three modes: Oscilloscope, Capture, Recorder.
In all analog channels signals can be displayed in the appropriate physical quantities (pressure, current, etc.)
Secondary voltage
This window allows you to automatically analyze the primary and secondary voltage signals of the ignition system, obtained with the help of capacitive Cx type or inductive Lx type sensors.
Diagnosing an ignition system with the help of a Lx4 sensor and automotive oscilloscope MT Pro, connecting the sensor to the engine, oscilloscope tuning, oscillogram recording while idle running and increased load. I’ll demonstrate all of this with an example of Seat Ibiza.
Power balance test
The full test allows detecting malfunction when the engine’s running unstably, as well as calculating the efficiency of each cylinder in different engine operating modes, detecting misfires (especially chaotic ones) and locating their cause (fuel system, ignition system, engine mechanics).

In-cylinder pressure test
This window allows you to automatically analyze in-cylinder pressure of the gasoline engine. According to the pressure signal, characteristics of the cylinder-piston group and the gas distribution mechanism are calculated such as the compression ratio, leaking in the combustion chamber, the gas distribution phase, the efficiency of cylinder’s fuel-air mixture filling, the exhaust system efficiency (clogged catalyst), and the ignition timing chart.

Cylinder comparison
This window allows you to conveniently display signals from all cylinders, which helps visually locate the deviations in the operation of one of the cylinders. Visual comparison provides universality, for it is not tied to a particular signal, but is based only on finding differences in the signals of the cylinders. You can analyze the signals of pressure pulsations in the intake manifold, exhaust pipe and fuel system, pulsations of crankcase gas pressure, injectors control signals, as well as any other periodic signals.
El.Power electrical equipment test
The full test allows assessing the state of the battery, the starter (solenoid relay and its terminals), the alternator (voltage regulator, rectifiers, their power circuits), glowplugs (for diesel engine cars). The test result with numerical values and their deviations is displayed in one chart.

Spectrum analyzer
Spectral analysis of an arbitrary signal; signal processing by an arbitrarily tuned digital filter. Signal spectrograms are made regarding time and crankshaft rotary angle, which makes it convenient to compare the noise from various ICE mechanisms.
Contents of delivery
- an oscilloscope - 1 pc
- a RJ45 FTP patch cord (shielded), 5e category, 5-metre long, with USB-port built-in power line - 1 pc
- a hanging hook for the device - 1 pc
Design of the device
The device has an impact-resistant metal case with a scratch-resistant powder coating. The steel case almost completely eliminates all external electromagnetic interference from the high-voltage circuits of the ignition system. The function of all connectors is signed on the case.
On the front of the oscilloscope there are nine BNC connectors for connecting to analog channels and a synchronization channel, as well as a ground terminal for the device.
On the rear panel of the oscilloscope there is a DJK-02 connector for connecting the power source, an RJ45 connector for connecting the device to the PC netcard, a threaded hole for screwing in the hook.
The printed circuit board of the device is designed considering interference from ignition systems and power circuits of the car. The elements are mounted on the automated assembly line.
