Tonghui TH2511 Direct-Current Low Resistance Tester Manual
The TH2511 is a direct‑current low‑resistance tester designed for measuring very small resistances in coils, motors, transformer windings, cables, switches, plugs and sockets. It uses a chopper‑stabilized zero‑drift amplifier and a five‑terminal measurement method to improve accuracy and eliminate lead and contact resistance effects.
The manual covers technical specifications, panel layout, measurement ranges, sorting functions, installation, operation, and detailed maintenance procedures, including warm‑up time, test current settings, and calibration checks. This manual is written in Chinese.
