current source of 34970a

Question asked by nitad54448 on Jul 6, 2014
i need to use a source of small current and I think that I can use the resistor measurement option of the 34970. according to manual it sources 10 microamps at 100 kOhm scale. So my idea is to put the 34970a in R measured mode at 100 kOhm and then use the 10 microamps in my circuit for other purposes. My problem is that "I don't know" when the 10 microamps are sourced, lets say for a 100 NPLC  : in the R measurement mode, half of the time the source should give "zero amps" 
thanks for any ideas (other than "measure it !")
