6、 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.
7、 Error message
1. When the instrument window displays "HH or LL", please check if the sensor wiring is correct.
2. When it is found that the temperature between channels is unstable due to mutual influence, please check whether the equipped sensor is an isolated type.
