Feature: 1. 200A CURRENT MEASUREMENT: This clamp meter is capable of measuring both AC and DC currents up to 200A without disrupting the circuit. It is a perfect troubleshooting tool that helps you quickly and safely resolve electrical issues in automotive, laboratory, factory, industrial, or home settings. 2. SURGE CURRENT TESTING: The surge current testing feature is designed to accurately catch DC AC surge currents, providing valuable insights into the behavior of electrical systems during peak loads. 3. ADVANCED FUNCTIONALITY: Ergonomically designed for maximum comfort during use, this clamp meter offers features such as high reliability, high safety, automatic range selection, and handheld operation. It also includes two modes, variable frequency drive (VFD) filtering and low impedance (LoZ) for accurate measurements in diverse applications. 4. PEAK HOLD FUNCTION: The peak hold function allows for convenient testing and recording of peak values, enabling analysis of intermittent or fluctuating electrical readings. 5. VERSATILE APPLICATIONS: This clamp meter is suitable for monitoring the operating conditions of on site equipment such as power distribution cables, motors, distribution panels, fans, pumps, etc. It is also useful for monitoring static currents in automotive engines or testing chip operating currents in automation research and development centers.
