This manual provides operating instructions, safety guidelines, and technical specifications for the Fluke 1625-2 Earth/Ground Tester.
The Fluke 1625-2 is a compact, rugged field instrument designed to perform all four types of ground measurements. It features a one-button measurement concept and supports three-pole and four-pole grounding tests, soil resistivity testing, selective testing without disconnecting conductors, and rodless loop testing using clamps.
The device includes advanced functions such as Automatic Frequency Control (AFC) to minimize interference from existing noise sources and R* measurements to calculate impedance at 55 Hz for more accurate fault detection. The manual covers setup, operation modes including control and measurement loops, data export, maintenance, and calibration procedures. This manual is written in Chinese.
