Chances are it will go to open value before it reaches tamper value Quote Link to comment Share on other sites More sharing options...

jackaddressable Posted May 17, 2018 Author Share Posted May 17, 2018 Is it above 1200 ohms that you'd see high res? I seem to recall that? Quote Link to comment Share on other sites More sharing options...
