Question: How to measure the cable identification instrument Answer: The usage and measurement steps of the cable identification instrument are as follows: 1. Disconnect the connection point between the grounding main line and the grounding body, or disconnect the connection points of all grounding branch lines on the grounding main line. 2. Insert the two grounding rods into the question: the measurement method of the cable identification instrument Answer: the use method and measurement steps of the cable identification instrument are as follows: 1. Disconnect the connection point between the grounding trunk and the grounding body, or disconnect all groundings on the grounding trunk The connection point of the branch line. 2. Insert two grounding rods into the ground 400mm deep, one is 40m away from the grounding body, and the other is 20m away from the grounding body.

3. Place the shaker in a flat place near the grounding body, and then connect it. (1) Use a connecting wire to connect the wiring pile E on the table and the grounding body E of the grounding device′. (2) Use a connecting wire to connect the terminal C on the table and the ground rod C 40m away from the grounding body′.

(3) Use a connecting wire to connect the wiring pile P on the table and the grounding rod P 20m away from the grounding body′. 4. According to the grounding resistance requirements of the grounding body to be tested, adjust the coarse adjustment knob (there are three adjustable ranges on the top). 5. Shake the watch evenly at about 120 rpm.

When the hand deflects, adjust the fine adjustment dial until the hand is centered. Multiply the reading set by the fine adjustment dial by the coarse adjustment positioning multiple, which is the grounding resistance of the grounding body to be measured. For example, the fine-tuning reading is 0.6, and the coarse-adjusting resistance positioning multiple is 10, then the measured grounding resistance is 6Ω.

6. In order to ensure the reliability of the measured grounding resistance value, the re-measurement should be performed again by changing the orientation. Take the average value of several measured values ​​as the grounding resistance of the grounding body.
