Hi 
I have got a Keithley 3706A. It works pretty well to measure with LV. 
I have to measure the same channel for several times. I managed this without any troubles but they relay is always switching for no reason. 
Cause this relay has a lifespan it will be a big problem after some hours, so I'm searching for a simple solution to measure one channels for x times without switching. 
  
Hope some one can help me. 
  
sincerely 
Kauzig
