Issue with VDC and ADC

Question asked by abert on May 19, 2017

I am presently using a 34970a to measure VDC and ADC over a period of time on a battery.  Whenever I attach both the VDC leads and ADC leads the current drops down to a very low level.  The current is usually about 74mA, but as soon as I attach the leads to measure voltage I am losing almost all of it down to 3mA.


For clarification I am running the current in series through the card on the negative terminal of the battery, which is hooked into a system.  The voltage is tapping off the battery in parallel.


Any help would be appreciated.


Thank You.
