Fluke 1625-2 地面測(cè)試儀概述

Fluke 1625-2 特點(diǎn)

易于操作：每一次測(cè)試時(shí)，測(cè)試儀都會(huì)提示所需使用的地樁或鉗口；大尺寸旋轉(zhuǎn)開(kāi)關(guān)確保即使戴著手套也能操作。

USB數(shù)據(jù)存儲(chǔ)和傳輸：能夠通過(guò)USB端口存儲(chǔ)和下載數(shù)據(jù)，內(nèi)部存儲(chǔ)器可存儲(chǔ)多達(dá)1500條記錄。

Fluke 1625-2 測(cè)量功能

無(wú)樁測(cè)試（僅用鉗口）

測(cè)量原理：只需使用鉗口即可測(cè)量接地回路電阻。將兩個(gè)鉗口夾在接地棒上，每個(gè)鉗口均連接至測(cè)試儀，其中一個(gè)鉗口感應(yīng)已知固定電壓，另一個(gè)鉗口測(cè)量電流，然后自動(dòng)測(cè)定接地棒的電阻。這種方法完全無(wú)需使用接地樁，且在測(cè)試時(shí)無(wú)需斷開(kāi)接地棒，保持接地系統(tǒng)完整性。但此方法僅適用于受測(cè)建筑物或構(gòu)筑物中有接地系統(tǒng)的情況，在只有一條通路接地（如許多住宅應(yīng)用）時(shí)，無(wú)法提供可接受的數(shù)值，則·須使用電位降測(cè)試法。

適用場(chǎng)景：可以在一些之前從未考慮過(guò)的位置執(zhí)行接地測(cè)試，包括建筑物內(nèi)部、電纜塔或任何無(wú)法接觸到土地的位置。

多種接地測(cè)量類型：是一款·面的測(cè)試儀，可以完成所有四種類型的接地測(cè)量，包括三極和四極電位降（使用地樁）、四極土壤電阻率測(cè)試（使用地樁）、選擇性測(cè)試（使用地樁和1個(gè)鉗口）、無(wú)樁測(cè)試（僅使用2個(gè)鉗口)。

Fluke 1625-2 技術(shù)參數(shù)

測(cè)量范圍：0.020Ω至300kΩ，不同的顯示范圍有不同的分辨率，如0.001Ω至2.999Ω分辨率為0.001Ω、3.00Ω至29.99Ω分辨率為0.01Ω等。

精度：±(讀數(shù)的2% + 2位數(shù))（在某些測(cè)量中），操作誤差為±(讀數(shù)的5% + 5位數(shù))。

測(cè)量時(shí)間：固定頻率時(shí)通常為8秒，使用自動(dòng)頻率控制時(shí)，·大30秒完成所有測(cè)量頻率循環(huán)。

開(kāi)路電壓：20/48V交流電，短路電流250mA交流電，測(cè)量頻率可手動(dòng)或自動(dòng)選擇94、105、111和128Hz(AFC)，55Hz(R*) 。

噪聲抑制：120dB(162/3、50、60和400Hz) 。

·大過(guò)載：·大Urms=250V（將不會(huì)啟動(dòng)測(cè)量）。

Fluke 1625-2 配套設(shè)備及套件

Fluke 1625-2 Ground Tester Overview

1. Characteristics

Easy to operate: During each test, the tester will prompt which stake or jaw needs to be used; the large-size rotary switch ensures operation even when wearing gloves.

USB data storage and transfer: Ability to store and download data via USB port, internal memory can store up to 1500 records.

2. Measurement function

Stakeless testing (jaws only)

Measuring principle: Simply use the jaws to measure the ground loop resistance. Two jaws are clamped to the ground rod and each jaw is connected to the tester. One of the jaws senses a known fixed voltage and the other measures the current and then automatically determines the resistance of the ground rod. This method does not require the use of grounding stakes at all, and there is no need to disconnect the grounding rod during testing, maintaining the integrity of the grounding system. However, this method is only applicable if there is a grounding system in the building or structure being tested. When there is only one path to ground (such as many residential applications), it cannot provide acceptable values, and the potential drop test method must be used.

Suitable scenarios: Ground testing can be performed in locations never considered before, including inside buildings, on cable towers, or anywhere where there is no access to the ground.

Multiple Ground Measurement Types: A comprehensive tester that can complete all four types of ground measurements, including three-pole and four-pole potential drop (using ground stakes), four-pole soil resistivity testing (using ground stakes), Selective testing (using ground stakes and 1 jaw), non-stake testing (using only 2 jaws).

3. Technical parameters

Measuring range: 0.020Ω to 300kΩ. Different display ranges have different resolutions, such as 0.001Ω to 2.999Ω with a resolution of 0.001Ω, 3.00Ω to 29.99Ω with a resolution of 0.01Ω, etc.

Accuracy: ±(2% of reading + 2 digits) (in some measurements), operating error ±(5% of reading + 5 digits).

Measurement time: usually 8 seconds when using a fixed frequency, and a maximum of 30 seconds to complete all measurement frequency cycles when using automatic frequency control.

Open circuit voltage: 20/48V AC, short circuit current 250mA AC, measurement frequency can be manually or automatically selected 94, 105, 111 and 128Hz (AFC), 55Hz (R*).

Noise suppression: 120dB (162/3, 50, 60 and 400Hz).

Maximum overload: Maximum Urms=250V (measurement will not be started).

4. Supporting equipment and kits

Supporting equipment: such as Geox probe cable, two clamps and conductor sets, etc. An external current transformer is also provided as an option. When measuring a single branch in a grounding system operating in a mesh, the current transformer has a conversion ratio of 80- 1200:1, can be used to measure high-voltage transmission towers without separating overhead ground wires or ground straps at the bottom of the tower, and can also be used to measure lightning protection systems without separating individual lightning protection conductors.

Kit contents: For example, Fluke1625-2KIT includes "User Manual", "Safety Instructions", QRG, Geox probe cable, two clamps,
