Default Re: Black Star Meteor 1000 Counter.

I know this thread is old now but... My TTi TF930 is not noisy. Floating, battery powered and same construction.

Use a shielded cable or scope probe and ground it properly and it’ll probably be fine. I usually use a 10x tek probe for my counter. The front end on these is very well isolated from the digital side of things.

Also try it on batteries. If you have an external DC supply it might be a switching supply and actually be the thing generating the noise.
