CA6423接地電阻測試儀@CA6423%

CA6423接地電阻測試儀@CA6423%

• 使用電位降法測量
• 測量接地電阻（2 P或3 P）
• 自動量程切換功能：自動選擇最佳量程檔位
• 抗干擾、抗噪聲設計
• 操作簡單，接線 - 按鈕 - 讀數
• LED燈隨時提示操作人員：有過高干擾、過高輔助地樁阻值或錯誤接線等情況
• 使用干電池提供電源
• 強固型外殼設計，防塵防雨（IP50）
• 三色接線端子設計，方便接線識別
• 可用于測量接地回路聯結點的連續性（導通性）

• 3極法，用于測量接地極或電網的接地電阻。本方法經常用于方便斷開接地極或電網接地的情況下、或是接地故障不易發生的地方。
• 2極法，用于測量接地導體聯結的導通性，及利用測量現場已存在（建立）的接地體來測量接地電阻。本測量法一般用在市區，因建筑物林立而無法布置輔助電極的情況下使用。在進行測量時，需要利用現場環境中已存在的良好接地體（如鐵質水管等）。

CA6423 ground resistance tester @CA6423%

CA6423 grounding resistance measurement range is 10mΩ to 1999 Ω, with automatic range switching function, can automatically select the best range gear. The operation is simple, just connect the test line, press the test button. Large LCD display can also indicates low battery, exceeding the measurement range, and the test lines connect the wrong stat

CA6423 uses 3 color terminal, convenient user terminalidentification. Instrument panel above the three LED lights, if an error occurs in the process of measuringsustainable to indicate to the user, so as to ensure theaccuracy and reliability of measurement.

CA6423 can protect 250Vac fuse

Product features:

The use of potential drop measurement

Measurement of grounding resistance (2 P or 3 P)

Product application:

CA6423 ground resistance tester, solid shell and the operation is simple, very suitable for maintenance personnel to carry out various tests. The anti interferencedesign, even in harsh testing environment (such as underhigh bulk current interference), still can make accurate measurements. CA6423 can be used for the following tests:

The 3 electrode method, for the measurement ofgrounding or grid grounding resistance. This method is often used to facilitate disconnection grounding orgrounding grid conditions, or grounding fault is not easy to take place.

The 2 electrode method, is used to measure thegrounding conductor connection continuity, and by measuring the field already exists (establish) ground toground resistance measurement. The measuring method is generally used in the urban areas, the use of thebuildings and auxiliary electrode cannot be arrangedunder the condition of. When in measurement, need to use well grounded in existing site environment in the body(such as iron pipe etc.).
