Clamp-type ground resistance tester digital resistance meter clamp type resistance measuring instrument lightning protection high-precision megohmmeter resistance meter tester 0.01-200

Wide range of uses: Ideal for ground resistance measurements in power, meteorology, oil fields, construction, and industrial electrical equipment. No need to remove the ground wire or use auxiliary electrodes for loop system measurements Advanced functions: Measures ground faults that cannot be detected by traditional methods, suitable for applications where traditional meters fail. Accurately measures the combined resistance of ground bodies and conductors Measuring range: Provides a wide measurement range from 0.010 to 200 with a resolution of up to 0.001. The fixture size is 32mm, ensuring versatility in a variety of test scenarios Accurate measurement: Utilizes loop resistance measurement, combining voltage and current coils. It measures the induced potential and current, and calculates the resistance using the formula R = E / I to obtain precise results Important note: Only suitable for measuring loop resistance, not for single-point grounding. Users can create an artificial loop near the ground electrode for testing. For detailed instructions, please refer to the user manual
