PROVA5635钳型接地电阻计是一款用于测量接地电阻和接地漏电流的仪器，具有非接触式测量的特点，使用起来安全且便捷。其接地电阻的测量范围为1～1500Ω，电流测量范围为0.20～30.00A。该仪器的钳部内径为35mm，能够适应不同直径的接地棒。它采用自动换档的方式，测量接地电阻时，不同量程的分辨率和准确性各有不同，例如在0.025～0.250Ω量程时，分辨率为0.002Ω，准确性为±1.5%±0.05Ω。在测量接地漏电流时，其准确性也较高，如在0.20～30.00A量程时，准确性为±2%±0.03A。该仪器的显示为4位9999计数的液晶显示，操作温度范围为0℃～40℃，操作湿度小于80% RH。其尺寸为10.5" x 4.1" x 1.9"，重量为750g（含电池），便于携带和使用。此外，它还配有标准电阻回路板、背带、使用说明书和9V电池等配件。

The PROVA5635 clamp-on ground resistance tester is an instrument used for measuring ground resistance and ground leakage current. It features non-contact measurement, which is safe and convenient to use. The device has a wide measurement range for ground resistance, from 1 to 1500 ohms, and a current measurement range of 0.20 to 30.00A. With a jaw inner diameter of 35mm, it can accommodate grounding rods of different diameters. It employs an automatic range switching mechanism. When measuring ground resistance, the resolution and accuracy vary depending on the range. For example, in the 0.025 to 0.250 ohm range, the resolution is 0.002 ohms, and the accuracy is ±1.5% ±0.05 ohms. When measuring ground leakage current, it also offers high accuracy. In the 0.20 to 30.00A range, the accuracy is ±2% ±0.03A. The device features a 4-digit 9999 count LCD display, and it can operate within a temperature range of 0℃ to 40℃ and a humidity level of less than 80% RH. Its dimensions are 10.5" x 4.1" x 1.9", and it weighs 750g (including the battery), making it portable and easy to use. Additionally, it comes with accessories such as a standard resistance loop board, a shoulder strap, a user manual, and a 9V battery.
