When detecting the power supply voltage of the quartz tube, first adjust the range of the multimeter to the "AC 250V" voltage block, and the red and black test pens are respectively placed on the power supply end of the quartz tube. At this time, observe the reading of the multimeter. If it is around 220V AC, it means that the power supply voltage of the quartz tube is normal.
