Overview

The YY-F660 instrument is a six channel intelligent temperature control instrument that can be simultaneously equipped with six PT100/PT1000 temperature sensors and K, J, R, and S-type thermocouples. It has an independent self-tuning mode and independent PID parameters, and can accurately control the six temperature channels. It can communicate with a computer RS485 serial port or drive micro printing timing. The communication protocol adopts the internationally recognized Modbus RTU protocol, which can form a centralized control and management system with PCs, PLCs, or touch screens. It can better meet the needs of customers in various complex and changing environments, and is widely used in industries such as automobiles, airports, computer rooms, food and drug production, etc.

5、 Self tuning operation

First, set the settings and then enter the menu，Set the hysteresis to around 0.5-1, set AT to ON, and the instrument enters a self-tuning state. The corresponding display window flashes and displays the "AT" character. At this time, the instrument is in positional control. After three oscillations, the instrument determines new parameters such as P, I, D and saves them, and resets to the control state.
