# Demo Mode

Demo mode lets you try COM Agent **without an instrument connected**. Instead of reading from a serial port, COM Agent generates a realistic demo measurement on demand — useful for learning the application, testing your output folder or keyboard setup, or giving a demonstration.

## Using demo mode

1. Set **Mode** to **Demo** in the Connection section. The COM port and baud settings disappear — they are not needed.
2. Choose your [output formats](rhopoint-com-agent-output-formats.md) and, if desired, [keyboard options](rhopoint-com-agent-keyboard-emulation.md), exactly as in live mode.
3. Press **Start**.
4. Press the **Right Alt** key anywhere — even in another application — to inject a demo measurement.

Each press of Right Alt produces one complete demo measurement, which is then written and/or typed according to your output settings, just like a real reading.

> [!info] Demo mode is the quickest way to verify your **keyboard emulation** setup: set Mode to Demo, enable keyboard output, click into a spreadsheet, press Start, and tap Right Alt — the values appear in the cells.

> [!info] The demo data uses the FT3 thickness format, so it works with CSV output and all keyboard values (Mean, Min, Max, Std Dev, Measurements).
