A magnetron detection method:SFyservice manual download site
1 ) between the test terminals filament of the magnetron , the resistance value should be less than 1Ω;SFyservice 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.SFyservice manual download site

Second, the high-voltage transformer Detection Methods: three windings :SFyservice manual download site
 SFyservice manual download site

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

Third, the high voltage capacitor detection method:SFyservice manual download site

1 ) requires the measurement instrument located at the highest resistance range ;SFyservice manual download site
2 ) normal : a, the two terminals of the capacitor test in a short time ( real -hop ) display turned on and the charging resistor of about 10MΩ; b, the resistor terminal and the housing should be infinite ;SFyservice manual download site
3 ) anomaly : a, short-circuiting the capacitor is always on ; b, open the internal resistance of the capacitor and its 10MΩ always show the resistance value of about 10MΩ ; c, when the high voltage capacitor circuit wiring inside the open , it will display an infinity resistance .SFyservice manual download site

Fourth, the high-voltage diode ( also known as unidirectional or high-voltage rectifier diode module ) detection method:SFyservice 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 ) .SFyservice manual download site
2 ) in a direction normal resistance is infinite , in the other direction is greater than 100kΩ.SFyservice manual download site
Five , two-way diode ( also known as protection diode ) detection method:SFyservice manual download site
1 ) The instrument is set to the highest resistance range ;SFyservice manual download site
2 ) Disconnect the wires , the protection diodes separated from the circuit ;
