The electronic tube is a very important part of the high cycle machine. In general, the electronic tube will not be damaged, but the necessary detection can not be less. Next, we will see how to detect the electronic tube of the high cycle machine.
How to detect the electronic tube of the high frequency machine:
1、 After the grid connection is cut off, start the high cycle machine to preheat the electronic tube. Use a multimeter to measure the resistance between the cathode and the grid, and the resistance between the cathode and the anode. If the forward resistance value is infinite and the reverse resistance value is small, the electronic tube is normal. If the forward resistance value is infinite and the reverse resistance value is small, the electronic tube is damaged.
2、 Energize the machine to preheat the electronic tubes. Use a multimeter to measure the voltage between the cathode and the grid, and the voltage between the cathode and the anode. Normally, the cathode grid voltage is 1.2-4V, and the cathode and anode voltage is 3-6V; If the voltage is 0V, it indicates that the electronic tube is damaged. Be careful that there is high voltage and strong current in the high frequency machine, so try not to try if you don't understand, and find a professional maintenance personnel for detection, otherwise it will lead to electric shock death.
So that's all for today's explanation. I believe you have a certain understanding of how to detect the electron tube of the high frequency machine. Thank you very much for your patience.
