5. 操作說明

The ETCR3200C supports multiple measurement methods. Always select the appropriate method for your application and ensure correct wiring.

5.1 Grounding Resistance Measurement

The instrument offers several methods for grounding resistance measurement:

• Three-Wire/Four-Wire Method: This is the standard and most accurate method.
  1. Connect the test leads and grounding stakes according to the 3-wire or 4-wire diagram on the case lid.
  2. Rotate the function switch to the "Grounding Resistance" mode.
  3. 按 測試 按鈕啟動測量。
  4. 結果將顯示在螢幕上。
• Double Clamp 方法： Used for measuring grounding resistance without disconnecting the ground system.
  1. Connect the two current clamps to the designated ports on the meter.
  2. Clamp one clamp around the grounding conductor to be tested and the other around an auxiliary grounding conductor.
  3. Select the "Double Clamp Method" on the rotary switch.
  4. 按 測試.
  5. The grounding resistance will be displayed.
• Two-Wire Simple Test: For quick checks where high accuracy is not critical.
  1. Connect the test leads as per the 2-wire diagram.
  2. Select the "2-Wire Test" mode.
  3. 按 測試.

5.2 Soil Resistivity Measurement (Quadrupole Method)

This method uses four grounding stakes (Winner method) to measure soil resistivity.

1. Drive the four grounding stakes into the ground at equal distances in a straight line.
2. Connect the test leads to the stakes and the meter's C1, P1, P2, C2 terminals according to the soil resistivity diagram.
3. Set the electrode spacing range on the meter (1m to 100m).
4. Rotate the function switch to "Soil Resistivity" mode.
5. 按 測試.
6. The soil resistivity value (in Ωm) will be displayed.

5.3 交流電流測量

The ETCR3200C can also measure AC current up to 600.0A.

1. Rotate the function switch to "AC Current" mode.
2. Open the jaws of the current clamp 和 clamp it around the conductor carrying the AC current.
3. The AC current value will be displayed automatically.

5.4 Data Storage and Communication

• The meter can store up to 300 groups of measurement data.
• 使用 讀 按下按鈕即可調出已儲存的資料。
• Connect the meter to a computer via the USB interface using the provided cable.
• Utilize the monitoring software (if provided by the manufacturer) to upload, save, and print data.

6、維護保養

• 打掃： 用柔軟的布擦拭儀器。amp 布。請勿使用磨蝕性清潔劑或溶劑。
