5 Key DPF parameters
All parameters are labelled directly on the device screen.
With Switch page to regen enabled, the device switches to this page automatically for the duration of a regeneration.
6 Parameters with max / min view
All parameters are labelled directly on the device screen. The device records a maximum and a minimum value for each of them – you switch between them by swiping up.

Settings
The options are grouped by topic – each one is described below.
Performance and data logging
Enables fast mode – the CAN bus is polled at a higher rate.
Logs data to the SD card once per second. All parameters read on the main page are recorded.
Information display
After the engine is switched off, the device shows the trip statistics for 10 seconds before going to sleep.
How to read the statistics
- Red shows the maximum recorded values.
- Blue shows the minimum recorded values.
- For the calculated and measured soot mass, white shows the difference since engine start. For example, a value of +1.21 means the soot mass increased by 1.21 grams between starting the engine and the end of the trip. A value of -0.50 means the soot mass decreased by 0.50 grams.
Signals passive regeneration on the main screen – the temperatures or the DPF icon turn orange. Detected from a drop in the measured soot mass.
During a DPF regeneration the screen switches automatically to page 5 – the one with the key DPF parameters.
After a regeneration finishes, the maximum values on page 7 (Differential Pressure Test) are reset automatically.
Audible signals
Audible signal when a DPF regeneration starts and finishes.
Signal volume: HIGH – loud, LOW – quiet.
Screen brightness
Switches between day and night mode automatically. With this option off, you switch modes manually by tapping the screen.

Setting the clock
- Swipe up or down over the hours field to change the value.
- Repeat the same over the minutes field.
- Press the SET button to save.
DTC – fault codes
Fault codes are read automatically when you open the DTC page.
Reads the DTCs (Diagnostic Trouble Codes) stored in the ECU memory. Use it to refresh the list manually.
Clears all DTCs stored in the ECU memory.
