1625 Earth/Ground Tester is a Fluke company-produced electric meter that can measure disturbance voltage, disturbance frequency, and ground resistance.
The Fluke 1625 Earth/Ground Tester manual provides detailed safety guidelines, unpacking instructions, and setup steps for the instrument. It explains the device’s functions, including interference voltage and frequency measurement, three‑ and four‑pole ground resistance testing, and selective measurement methods.
The document also covers operation details such as battery monitoring (LO‑BAT), temperature ranges, display specifications, measurement accuracy, and maintenance procedures. Technical specifications for voltage, frequency, resistance ranges and environmental limits are listed in the specifications section. This manual is written in Chinese.
| 工作温度范围 | -10 °C … +50 °C |
|---|---|
| 操作温度范围 | 0 °C … +35 °C |
| 存储温度范围 | -30 °C … +60 °C |
| 显示屏分辨率 | 4 位（2999 数字） 7 区段液晶显示 |
| 测量误差极限 | ±30 % |
| 电池低电量指示阈值 | 约 10 % 电量 |
LO‑BAT appears on the display when the battery capacity falls to about 10 % of its rated value.
It uses automatic frequency control (AFC) to select a measurement frequency that minimizes interference.
