# F Category Options and Descriptions

## F01 Sim. Rate (Simulation Rate)

Defines the instantaneous flow rate to simulate. The unit applied will follow the settings defined in the B classification parameters. Default Value 60.

| Parameter Input Range | Value  |
| --------------------- | ------ |
| Default               | 60     |
| Minimum               | 0      |
| Maximum               | 100000 |

## F02 Sim. Mode (Simulation Mode)

Activating this option enables the simulation function, which is disabled by default. When enabled, the NPN outputs (excluding pulse), RS485 communication, and analogue current output will operate based on the simulated data and changes in the totalised flow. Default Value 0.

* Please note that the totalised flow and historical data will be affected.
* The main screen will display an indication that the system is in simulation mode. Ensure the relevant communication functions are enabled for proper operation.

| Options | RS-485 Numbers | Remarks |
| ------- | -------------- | ------- |
| OFF     | 0              | Default |
| ON      | 1              |         |

After selecting a command, confirm whether to **Save** or **Not Save**.

## F03 Sim. PulseHz (Simulation PulseHz)

Under this page, pulse signal will be outputted according to set frequency within value 0 to 1000. Please set up NC/NO of pulse according to parameter E01, and pulse width according to parameter E03. Default Value 10.
\
It operates whether NPN info is turned on or not.

| Parameter Input Range | Value |
| --------------------- | ----- |
| Default               | 10    |
| Minimum               | 1     |
| Maximum               | 1000  |

# Agent Instructions
This documentation is published with GitBook. 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.lorric.com/qr/fp-as310-paddle-wheel-flowmeter-manual-en-v1/parameters/f-category-options-and-descriptions.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
