It uses high-frequency, high-power constant current switching technology to measure micro-ohm contact resistance with exceptional accuracy and stability. The instrument is suitable for testing contact resistance in circuit breakers, switches, power cables, and welded joints, ensuring reliable performance in power plants, substations, and manufacturing environments. It features a 7-inch high-brightness color touch screen for simultaneous display of output current and measured resistance, with bilingual interface support. Test data can be stored on a USB drive, Bluetooth device, or transmitted via RS232 for easy data management. The HZ-5200 also includes intelligent power management for efficient energy use, built-in thermal and reverse potential protection, and an internal micro-printer for instant report printing. Its four-terminal measurement method effectively eliminates lead resistance error, providing precise and consistent results for professional high-voltage switch testing applications.disconnection detection, power failure protection, and overheat protection during testing. These features reliably safeguard the instrument from reverse voltage impact and provide an audible alarm.
