MBR3045CT and SR3045LCT Schottky diode testing help.

[Baste]

Hello experts,
Can anyone educate me on how to test MBR3045CT and SR3045LCT Schottky diodes? I'm totally a newbie in electronics, so forgive me if I have cheap tools. In my effort to repair a Gigabyte PSU, I stumbled upon the two diodes, which I suspect are leaky. I tested this with my two cheap multimeters and the newly bought LCR-T4 MC328, and I got confusing results. Below are my test results.

Aneng ST182 Meter.

Diode mode.
MBR3045CT:
Diode mode
Pin 2-1 - 0.150v
Pin 2-3 - 0.150v
Both show OL on reverse both shows OL on reverse

SR3045LCT:
Diode mode.
Pin 2-1 - 0.096v
Pin 2-3 - 0.096v
Both show OL on reverse

Alexan meter reads slightly lower
MBR3045CT
Pin 2-1 - 0.130v
Pin 2-3 - 0.130v
SR3045LCT:
Pin 2-1 - 0.080v
Pin 2-1 - 0.080v
Both show OL on reverse

Resistance reading.
MBR3045CT:
Pin 2-1 Pin and 2-3 445K ohms. When I reverse the leads, I get 149K
pin 1-3 reads 140K both reverse and forward.

SR3045LCT:
Pin 2-1 Pin and 2-3 223 ohms. When I reverse the leads, I get 15K and 16Kohms readings.
pin 1-3 reads 15K both reverse and forward.

I uploaded photo's of the ESR meter readings.

they work.
schotky diodes are tricky to test because the voltage drop is very low with low test voltages and no real current.
some meters cant even give a stable reading!

if they fail they short out - so easy to see a bad one.

Thank you, much appreciated.

you may want to update the software in that tester btw.

Hmmm I needed to buy a BIOS flasher anyway. I received an Asus motherboard with a faulty BIOS update, and it became bricked. Thanks for the advice
