Hello all
Does anyone on the board have and experience with the Keithley 6517A Electrometer? Specifically with the relative measurement function and setting it via GPIB.
I can not for the life of me get this damn thing to accquire the current for the relative measurement and then subtract it from the other readings.
I know this is specialized equipment but maybe someone has some experience.
I called Keithley Tech Support and they put an engineer on it. It seems he can't figure it out either. Pretty damn sad, but I need to have this working by this Friday.
I can do measurements without the realative measurement, but only to 2.5 picoamps. That seems to be the noise floor.
I thought I had it working, but then I made some measurements and it didn't look like it was subtracting any value from the measurements. Then I sent the commadn via GPIB to read the realative value it read back zero.
