FLUKE PM3082 on power up it blows its fuse....
« on: February 06, 2020, 06:14:15 pm »
Dear All ,

I am aware of the other 2 postings regarding the FLUKE PM3082 , but nothing that could be helpful to my issue ,

so after digging around found the service manual,

I looked and located all Class Y(input caps) capacitors in case they wore cracked and replaced them

and now I have no idea where to go next .... and I am quite afraid around high power CRT stuff because I've never worked with them ,

so if anyone can help me how to diagnose the problem it would be nice.

Last information the oscilloscope was on and working prior to just burning the fuse 1 day while being idle

I hope someone can help me ,

Thank you in advance
