Chamber Current and Capillary Current

Question

Hi, 
 How are the capillary current and chamber current measured? I see that they are measured in nanoAmps and microAmps, respectively. Are they measured through a detector? And if so, where is this detector located? 
 
 The instrument we use is a Triple Quadrupole 6495C. 
 
 Thanks

Sorry what i mean here is - its like if water getting drained from Tank - to maintain the level in the tank more liquid will flow - in this case it is not applying current what we see indirect way of looking at number of ions in the source or number of ions forming - if its dirty spray shield and cap - i suppose you will see less feed back current becasue the charged ions will not get discharged on the plate but will get struck on the dirt - ( i guess)
