I want to use the thread for asking something.

I measure diode p6ke200a out of circuit
I am using Resistance check method which i saw here

Anode-Cathode Diode Resistance Test
i see 19KoHms. is this reason to think that the diode is faulty? I read about the "right value" Hundred of KOhms but this is just 0.2 of hundred.

Cathode-Anode Diode Resistance Test
i see OL

thanks in advance

 

P6KE200A is not a normal diode and you won't get meaningful by measuring it with a multimeter (unless it happened to be short circuit, which yours isn't). It is a transient volrage supressor or TVS.

 

i just see zd number x and google "how to test zener diodes with multimeter"
Am i using the wrong method and why?

What is the correct way to test the diode?

That method is OK for testing a diode but the P6KE200 is not a diode.
