The oscilloscope’s input circuit accepts a wide range of voltages and is protected by surge protection. Thus, with the DM-1 oscilloscope, we can diagnose both low-voltage sensor circuits and ignition system control components.

The diagnoscope function allows you to select oscilloscope settings according to the selected component. After selecting a component from the list, we gain initial settings for time base and gain, as well as an example waveform.

The device works with a PC program, allowing you to view and record waveforms on your computer. In addition, the software package includes the Common Rai pressure testing program.

The price of the diagnoscope also includes the COMMON RAIL PRESSURE TESTER program.

It allows you to measure the pressure on the COMMON RAIL strip and is designed for sensors with different pressure ranges (it is possible to enter the maximum pressure of the sensor).

In addition, when the option is switched, the program measures the signal fill factor (PWM) on the pressure control valves.

DM-1 – FAQ


I lost my software CD. How can I get the software?

The software for the device can be downloaded after prior registration and logging in to our website:


My computer does not have a serial port, how do I connect the device to my computer?

In the case of computers with USB ports, you can use the USB -> Serial Port (COM) adapter. It is good to choose a good quality product, e.g. based on the FT232RL chip. If you have an older software, please download the current version.


The original power supply has been damaged. Which power supply should I use?

In the event of a defect during the warranty period, please contact our service. The device requires a stabilized 12V power supply with a 5.5 / 2.5mm connector (positive tip, negative sleeve).


I have an older DM-1 device. Is it possible to replace the battery or repair the device?

We offer both the possibility of replacing the battery and the possibility of repairing or calibrating older devices. We invite you to contact our service.
