The AT816A is a precision LCR digital bridge offering a frequency range of 20 Hz to 200 kHz and continuous voltage levels from 0.01 V to 2.00 V. It provides automatic range selection, programmable triggers, and SCPI/simple protocol interfaces, making it suitable for laboratory and mid‑range production environments.
The manual describes measurement parameters (L‑Q, L‑R, C‑D, etc.), display formats, record management (20 groups), and detailed settings for comparators, triggers, and output signal levels. It also lists hardware interfaces (RS232C, ExHandler) and compatibility with 4284A and GR1689 signals. This manual is written in Chinese.
