ProSight Digital Earth Resistance Tester 0.5 5.2Ah
ProSight Digital Earth Resistance Tester 0.5 5.2Ah is a digital earth resistance tester designed for testing and verifying electrical grounding systems. It is widely used in electrical installations, industrial maintenance, telecommunications, utility networks, and lightning protection inspections. Key features include high-accuracy earth resistance and voltage measurement, rechargeable lithium battery, 400-record memory, USB data transfer, and precision 2-wire and 3-wire testing.
What is the Product?
ProSight Digital Earth Resistance Tester 0.5 5.2Ah is a portable professional instrument used to measure the resistance of grounding systems and the presence of earth voltage. Proper grounding is essential for protecting personnel, electrical equipment, and installations from electric shock, lightning, and fault currents.
Using advanced digital measurement technology with automatic frequency control (AFC), the VKCR3000C delivers stable and accurate measurements even in electrically noisy environments. The tester supports both precision three-wire testing and simplified two-wire measurement, making it suitable for field inspections, preventive maintenance, commissioning, and troubleshooting. Its rechargeable lithium battery, large backlit LCD, internal memory, USB communication, and rugged IP65 carrying case make it ideal for demanding industrial and outdoor applications.
How It Works
The tester injects a controlled AC test current into the grounding system through auxiliary earth rods and measures the resulting voltage drop. It then calculates the earth resistance according to established electrical testing principles.
For simplified testing, it also supports a two-wire measurement method. The instrument automatically compensates for test lead resistance, reducing measurement errors while AFC technology minimizes interference from surrounding electrical noise. Test results can be stored internally and transferred to a computer via USB for documentation and reporting.
