Product Description

High Precision Earth Down Ground Lead Continuity Resistance Tester

Performance

This instrument abandons the traditional manual hand-cranked power generation method, adopting advanced medium/large-scale integrated circuits and DC/AC conversion technology to integrate three-terminal and four-terminal measurement methods into a new type of grounding resistance tester.
    The working principle involves the internal DC/AC converter transforming direct current into low-frequency alternating constant current. This current flows through the auxiliary grounding electrode C and the measured object E to form a loop, generating an AC voltage drop on the measured object. The voltage drop is amplified by the AC amplifier via the auxiliary grounding electrode P, then demodulated and displayed on the meter. With the range switch, three measurement ranges are available: 0-2Ω, 0-20Ω, and 0-200Ω.
    This instrument is suitable for measuring grounding resistance of various installations in industries such as power, postal/telecommunications, railways, communications, and mining, as well as low-resistance conductor resistance values. It can also measure soil resistivity and ground voltage.

Features:

•Structural design: High-strength aluminum alloy casing.
• Circuit design: Phase-locked loop synchronous tracking demodulation and switched-capacitor filtering to suppress power frequency and RF interference, ensuring strong anti-interference capability.
• Technology: DC/AC conversion to generate low-frequency constant current for measurement.
• Tolerance: Auxiliary grounding resistance ranges: 0-2kΩ (RC) and 0-40kΩ (RP), without affecting measurement accuracy.
• Operation: No manual balancing required; features a 3½-digit LCD display. Measures grounding resistance, low-resistance conductors, soil resistivity, and AC ground voltage.
• Fault indication: Displays "1" for open circuits (overflow), conforming to conventional measurement practices.
