This document is a user manual for TCN series counters, which introduces the parameters, features, and precautions of the instrument. The counter uses a high-performance microprocessor for control and has features such as accurate measurement and strong anti-interference ability.
This manual describes the features, technical parameters, wiring, and operation of the TCN series counters. It covers four‑digit (TCN‑P41A/P41B) and six‑digit (TCN‑P61A/P61B) models, their LED displays, and available output functions (F, N, R, C).\n\nSafety and usage notes are included, such as environmental limits, recommended input signal levels, and precautions to avoid damage to the device. The document also provides timing adjustments and panel button functions for setting delay and output modes. This manual is written in Chinese.
