The BT series intelligent instrument instruction manual of Bert Industrial Control is a product with rich functions and easy-to-use operation. It adopts industrial-grade single-chip microprocessor, four-and-a-half A/D conversion and digital correction and filtering technology to ensure measurement accuracy. The product has multiple linear and nonlinear input specifications, which can be selected online. It has an advanced modular structure, and is easy to configure, maintain, replace and expand functions. The product also has perfect self-tuning and self-adaptive functions to reduce the debugging workload. The product supports external output and can be used to construct cascade and ratio control systems. It supports RS232 and RS485 communications, and can directly drive the micro printer to print data at a fixed time. The product has two-level menu configuration and four-level operating permissions to ensure system security.
This manual introduces the BT series intelligent meters, describing their performance, technical specifications, and the meaning of each model number. It also explains how to install the instrument, connect terminals, and configure output modules.
Key sections include a performance overview, detailed technical specs, model‑specific operation instructions, terminal wiring diagrams, SCR trigger wiring, and a chapter on error codes and communication setup. This manual is written in Chinese.

Short‑circuit terminals 8 and 10 and set the LCb parameter to 0.0, then restore the LCb value after calibration.
Use the SET function to define the lower (F.S‑L) and upper (F.S‑H) limits; for example, F.S‑L = 0 MPa and F.S‑H = 10 MPa gives a 0‑10 MPa range.
The meters support RS232 and RS485 serial communication interfaces.
Adjust the PLoc parameter: 0 allows full editing, 1 restricts editing of menu parameters, 2 locks both values, and 1008 unlocks the secondary menu for full access.
