Common questions about manuals, registration, and support for this brand.
You can program the control type between PID control and ON-OFF control directly through the system parameter menus. Refer to the user manual for the specific menu code (often under 'oPA' or output type settings).
Many ZGCJ measurement instruments utilize RS485 communication with Modbus-RTU protocol. The default settings are typically 8 data bits, 1 stop bit, no parity, and a 9600 baud rate.
Depending on the model, ZGCJ controllers support various input sensors including PT100, PT1000, Cu50, and multiple thermocouples (K, E, S, J, T, B).
Navigate to the PID parameters menu and locate the 'At' (Self-adjust) setting. Change its value from 0 to 1. The controller will automatically calculate and adjust the PID values according to your specific environment.
