Electric Fittings Multimeter To Check The Quality Of Fluorescent Tubes

Dead End Clamp Multimeter Check the Quality of Fluorescent Tubes:

When measuring, it is best to choose a megohmmeter with a rated voltage of 1000V. Set the multimeter switch to 500V. When wiring, pay attention to the consistency of the polarity of the two meters. Check the wiring diagram of the fluorescent tube. Shake the megohmmeter at a speed of 120r/min. Then, a DC voltage of about 1000V is added between the two groups of filaments, replacing the 600-700V high voltage of the ballast product, so that the argon gas inside the tube is ionized, and the fluorescent powder on the tube wall is stimulated to emit light. The gas in the fluorescent tube has a negative resistance effect when discharging, so that the voltage drop of the tube is below 300V.
