How To Use The Circuit Fitting Pointer Multimeter To Measure The Polarity Of Each Leg Of The Rectifier Bridge?

Insulation Piercing Connector pointer multimeter to measure the polarity of each foot of the rectifier bridge?

Set the multimeter to Rx1k, connect the black probe to any pin of the bridge rectifier, and use the red pen to measure the other three feet in turn. If the readings are all infinite, the black pen is connected to the positive output of the bridge rectifier. If the readings are 4-10k, the pin connected to the black probe is the negative output of the bridge rectifier, and the other two pins are the AC input terminals of the bridge rectifier.
