VKCR9400 Zinc Oxide Lightning Arrester Clamp Live Tester

1. There is no need to cut off power supply during the test, no need to remove the arrester, safe and fast to operate.

2. The current clamp with strong anti-interference ability, and with microampere level leakage current test ability, which can test 1uA weak current, alsocan be used as high accurate clamp ammeter.

3. Adopt wireless communication mode, the master instrument can close or open the detector remotely, check the working condition of the clampjawand reading current data.

4. The detector can be used to connected with insulation rod, especially convenient for testing
