UNI-T UT622A Handheld LCR Meter
The UNI-T UT622A is a handheld LCR meter designed for portability and accurate measurement of inductance (L), capacitance (C), and resistance (R). It is engineered for use in various environments, from laboratories to production lines, offering a practical solution for technicians and engineers who require reliable component testing on the go. The device is part of the UT622 series, characterized by its robust functionality and user-friendly interface.
The meter features a clear and intuitive 2.8-inch TFT LCD display with a high-brightness white backlight, ensuring readability in different lighting conditions. Its operation is streamlined with a logical button layout, allowing users to easily select primary and secondary measurement parameters, test frequencies, and speeds. The design prioritizes ease of use with functions like data hold, a recording mode for statistics, and both three-terminal and five-terminal test options for flexibility in connecting to components.
At its core, the UT622A provides essential LCR measurement capabilities with a focus on accuracy and speed. It supports automatic component identification and offers features like open and short circuit correction to enhance measurement precision. Built with a long-lasting rechargeable battery, it is ideal for fieldwork, providing up to 8 hours of operation. It also includes a Mini-USB interface for communication and data transfer, supporting SCPI commands for remote control and integration into automated systems.
