A shorted diode would measure same low value in both directions (swap probes Red and black and remeasure).

If your multimeter has a DIODE Setting use that, otherwise, lowest ohms setting that works.

Analog Meter? a good diode will be low ohms in one direction and 10X higher than that the other direction (when swapping probes to either end of diode).

A digital ohmmmeter with a diode setting will be OL or infinity ohms in one direction and between 200 and 700 ohms in the other direction. Of course checking components in the power supply, discharge all capacitors!
