無樁測試
Fluke 1623-2 接地測試儀只需使用鉗口即可測量接地回路電阻。使用這種測量方法時，將兩個鉗口夾在接地棒上，每個鉗口均連接至測試儀。完全無需使用接地樁。其中一個鉗口感應已知固定電壓，另一個鉗口測量電流。然後，測試儀會自動測定接地棒的電阻。這種測試方法僅適用於受測建築物或構築物中有接地系統的情況，不過大多數情況都是如此。如果只有一條通路接地，如許多住宅應用中所採用，無樁測試法無法提供可接受的數值，則必須使用電位降測試法。
採用無樁測試時，無需斷開接地棒 - 保持結合的接地系統在測試中的完整性即可。如今無需再花費時間為系統上的接地棒放置和連接地樁，這能夠節約大量的時間。在一些您之前從未考慮過的位置，您也可以執行接地測試，包括建築物內部、電纜塔或任何您無法接觸到土地的位置。
最全面的測試儀
Fluke 1623-2 是一款與眾不同的接地測試儀，可以完成所有四種類型的接地測量。
- 三極和四極電位降（使用地樁）
- 四極土壤電阻率測試（使用地樁）
- 選擇性測試（使用地樁和 1 個鉗口）
- 無樁測試（僅使用 2 個鉗口）
