INVT inverter series maintenance # Voltage regulator tubes and other basic problems can be solved. Compared with the motherboard, it is easier to see obvious faults. By using the optical communication system, whether the electrolytic capacitor is leaking, etc., use a multimeter to measure three The phase result is: = The oscilloscope is mainly used to observe the electrolytic capacitors in the relevant circuits. The electrolytic capacitors in the circuit should not be close to high-power heating components, digital spectrum analyzers, etc. Wuxi Anxu is the first choice for INVT inverter D series maintenance. Your choice is right.
