How to measure resistance across a capacitive load using an Agilent 34410A in GPIB mode
OK, I got it to work. This procedure will do:

CONF:RES
INIT
&lt;place code here to wait a little bit&gt;
INIT
FETCH?


Basically, "CONF:RES" will place the meter in resistance measurement mode. The, first "INIT" will apply voltage and measure resistance and will place the first measurement in memory. At this point this first measurement is accessible via "FETCH?" but this is not what I want (this is the low ohmic value before the caps are charged). After a few seconds of waiting, a second "INIT" will take another measurement of the resistance while not ceasing to apply voltage between the two INITs so the caps will be charging all along. The "FETCH?" will then return the final resistance value at equilibrium when all the caps are charged.
