Product Application
This multi-functional tester serves grounding safety acceptance and routine maintenance in power industry. It tests grounding condition of transmission towers, distribution cabinets and substation auxiliary grounding networks.
In communication sector, it completes inspection for base stations and computer equipment rooms. It is also suitable for lightning-protection inspection of gas stations, chemical plants, solar stations and buildings. The clamp-on mode enables fast on-site testing without cutting off grounding connection. Three/four-wire mode delivers high-precision measurement for single-point grounding electrodes. Soil resistivity function helps engineers for new grounding system design. It is widely adopted by inspection institutes, engineering contractors and field maintenance teams.
FAQ
Q: What precautions should be taken before clamp-on resistance measurement?
A: Squeeze trigger several times to ensure the clamp jaw closes tightly. Keep jaw contact surface clean. Start measurement only after "OL" symbol appears on screen.
Q: What technical information shall we prepare for quotation of Clamp-on Ground Resistance Tester?
A: Please confirm required measurement functions, Bluetooth option requirement, certification demands, accessory configuration and destination port information.
Q: Can this instrument measure single independent grounding electrode?
A: Single-point grounding needs three-wire or four-wire test with auxiliary grounding stakes. Pure clamp-on mode is applicable for multi-point parallel grounding loop only.
