# 2.4.1 RSSI（訊號強度）

在儀表畫面上有二組RSSI 數值分別代表上下游探頭所接收到的訊號強度。介於0-100％ 之間，建議在10％ 以上以維持系統正常運作，若發現RSSI過低或不穩定跳動時，請參考以下幾點調整方法： 

● 嘗試微調探頭之間的距離。 

● 更換探頭架設位置。 

● 確認管內是否有沈澱物。 

● 檢查管外壁是否有過厚的鐵鏽、油漆等物質，嘗試刮除平滑後勻塗佈更多的耦合劑。 

● 兩個探頭所發出的訊號可能不在同一直線上，試著慢慢移動探頭直到有更好的RSSI值。並且檢察探頭距離是否有誤。 

● 做完上述任何動作後，務必再次檢查探頭距離是否偏離過多，過度的偏移將產生流量量測結果的誤差。 

● 檢查設定中Meter→Rx Peak Level中設定值，若架設的管徑較大，拉線較遠等因素造成RSSI總是偏低，可以嘗試調整此設定值，相關設定注意事項請參考後續說明。

## 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-v3/2.-an-zhuang-fang-shi/untitled-1/2.4.1-rssi-xun-hao-jiang-du.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.
