Easy Microwave main components detection methodsMM2service manual download site
    1 , magnetron methods:MM2service manual download site
    1 ) between the test terminals filament of the magnetron , the resistance value should be less than 1Ω;MM2service manual download site
    2 ) between any terminal and magnetron filament (ground ) test , the resistance should be infinite ; If the resistance is small or zero, then the magnetron should be replaced.MM2service manual download site

2, the high-voltage transformer Methods: three windings :MM2service manual download site
    1 ) primary winding , approximately 1.45ΩMM2service manual download site
    2 ) secondary winding , about 112ΩMM2service manual download site
    3 ) filament winding , less than 1ΩMM2service manual download site
    If the measured readings do not meet the above data, the high-voltage transformer may be faulty and should be replaced.MM2service manual download site

3 , high voltage capacitor method :MM2service manual download site
    1 ) requires the measurement instrument located at the highest resistance range ;MM2service manual download site
    2 ) a normal phenomenon :MM2service manual download site
    a, the two terminals of the capacitor test in a short time ( real -hop ) display turned on and the charging resistor of about 10MΩ;MM2service manual download site
    b, terminal and shell resistance should be infinite ;MM2service manual download site
    3 ) abnormal phenomenon :MM2service manual download site
    a, short-circuiting the capacitor is always on ;MM2service manual download site
    b, open the internal resistance of the capacitor and its 10MΩ resistor values ​​are always displayed about 10MΩ 's ;MM2service manual download site
    c, when the high voltage capacitor circuit wiring inside the open , it will display an infinite resistance .MM2service manual download site

4, the high-voltage diode ( also known as high-voltage rectifier diodes or unidirectional component ) method :MM2service manual download site
1 ) The instrument is set to the highest resistance range ( note : the measuring instrument must also have at least a battery voltage of 6V , otherwise in both directions will be displayed infinite resistance ) .
