1.1 Primary rectifier V5
• Primary side primary rectifier diodes can be measured one at the time
• Diodes must be measured both forward bias and reverse bias condition to make sure they are fine
• Check the diodes using the multimeter diode function to measure their threshold voltage 0,3…0,6 V
Measurings:
Positive test lead Negative test lead Result
X1, X2, X3 (one at time) X16 0,3-0,7VDC
X16 X1, X2, X3 (one at time) no value
X20 X1, X2, X3 (one at time) 0,3-0,7VDC
X1, X2, X3 (one at time) X20 no value
