As it surges forward, Taihua Instrument will always follow the path of enterprise development that emphasizes intelligent innovation and continuous transcendence, promoting "Made in China" to the future and the world.
Slide down
1, the transmitter power supply is normal
If it is less than 12VDC, check whether there is A large load in the loop, and the input impedance of the transmitter load should meet RL≤(transmitter supply voltage -12V)/(0.02A)Ω
2, whether to carry out integrated debugging
Integrated debugging
3, whether the thermal resistance (or thermocouple) and the enclosure insulation meet the requirements
If the insulation does not meet the requirements, the corresponding insulation treatment should be carried out.
