TH2828/TH2828A/TH2828S is a high-precision, high-performance, wide-range, multi-function component test instrument, which adopts the most advanced automatic balancing bridge principle in the world. It has the widest impedance measurement range, the highest basic accuracy, the fastest measurement speed, and the most powerful functions. It is mainly used in electronic component design, inspection, quality control and production testing, as well as circuit design and development and material (electronic materials and non-electronic materials) research and development.
The TH2828 series is a precision LCR digital bridge and automatic component analyzer offering a 20 Hz‑1 MHz frequency range, up to 6 000 test points, and 0.05 % basic accuracy for the TH2828/TH2828S models. It supports four‑terminal pair connections, programmable AC/DC voltage and current, and high‑speed measurements (as fast as 25 ms per reading at 1 MHz).
The instrument includes a 320×240 pixel LCD, internal non‑volatile memory for 20 preset configurations, USB storage, and communication options such as RS‑232C, GPIB and optional Handler interface. Optional accessories provide extended test cables, high‑current bias sources, and various test fixtures for components, PCBs and materials. This manual is written in Chinese.
