Controls and Navigation

Physical Button Operations

The device’s physical buttons mirror the on-screen functions for flexible operation.

ButtonFunctionDirection KeysUsed to zoom the waveform in/out (Up/Down) or shift it (Left/Right).DefaultInstantly restores all parameters to calibrated factory initials to fix display errors.OK / TriggerConfirms selections and manages signal triggering.

Touch Gestures

The T80 supports intuitive smartphone-style gestures for waveform manipulation:

• Vertical Stretch/Pinch: Adjusts the voltage scale ($V/div$) to make the signal taller or shorter.
• Horizontal Stretch/Pinch: Adjusts the time base ($mS/div$) to expand or compress the waveform view.

Waveform Management (Waveform Viewer)

The T80 serves as a personal diagnostic knowledge base by organizing data into two categories:

• Factory Data: Access standard engine timing waveforms from major brands like Renault, Cummins, Hino, and Foton.
