When enabled, the flow setting displays the value defined in **F01 Sim. Volume**. In this mode, **OCT** (excluding pulses), **RS485**, and analog current outputs respond according to the simulated data, allowing verification of output values. {% hint style="info" %} If the **F02 simulation function** is enabled, all data displayed on the **main screen** will show **simulated values only**.\ In this mode, the **main screen backlight will remain amber (orange)** to indicate the simulation status. {% endhint %} {% hint style="danger" %} * Enabling **Simulation Mode** may alter historical total flow. The main screen turns **orange** and relevant communication outputs must be active. * When using 4–20 mA output, **E06 Iout Def.** must be enabled to display data. {% endhint %}

Button Functions (Click to Expand)

The main unit has **four buttons**. The **bottom line (Line 3)** of the LCD displays the current function of each button. Under normal operation, the button functions are as follows: *

**Blue Button:** Leftmost button: Return, exit, or save settings. * Gray Direction Buttons: *

**Left Gray:** Previous Page, decrease value, or select item *

**Right Gray:** Next Page, increase value, or select item *

**Orange Button:** Rightmost button: Enter settings, edit, or confirm selection {% hint style="danger" %} **Do not hold buttons for extended periods to avoid damage.** {% endhint %} {% hint style="info" %} Button functions may change depending on the operation context to improve usability or prevent accidental presses {% endhint %}

Simulation Mode Instructions (Click to Expand)

> **Simulation Mode** is used to output simulated flow values for testing communication and signals. Related parameters include [F01 Sim. Volume](/qr/fp-as310-english-v5/parameters/f-simulate/f01-sim.-volume.md) and [F02 Sim. Mode](/qr/fp-as310-english-v5/parameters/f-simulate/f02-sim.mode.md), and additional settings depending on communication type: > > * **4–20 mA:** **E06 Iout Def.** > * **NPN Pulse:** **E01 NO/NC**, **E02 OCT Definition** > * **RS485:** **E04 Modbus ID**, **E05 Baud Rate** {% stepper %} {% step %} ### F02 Turning on Simulation Mode ``` F02 Sim.

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.lorric.com/qr/fp-as310-english-v5/user-interface/mo-ni-mo-shi.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
