# 2.2.2 儀表接線方式

探頭數量為一組兩個，分別為上游探頭與下游探頭；每一個探頭有三條運接線，因此在儀表上共有六個接點，如下圖所示。將探頭依照下圖順序進行線路的安裝，若部分探頭型號僅有二條線沒有接地隔離（Gnd）接線，則安裝+、- 兩條條線即可。

# 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 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/fu-tx310-ultrasonic-flowmeter-manual-chinese-v2/2.-an-zhuang-fang-shi/2.2-chao-yin-bo-tan-tou/untitled-1-1.md?ask=<question>&goal=<endgoal>
```

`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.
