Hey,
I am using the Keithley 6430 to source I and measure V (with Pre-Amp Connected) .. All works well as long as I stay above MicroAmpere Range (Meaning 1E-6 Amps to 105mA) the instrument works fine but when I try to source below 1E-6Amp the instrument just kind of Hangs up on the start current value and never moves further and after a certain time has passed absurd reading are displayed as a result ... The VI and screenshot is attached ..
Does anyone know why this happens ??? (Sweeping Voltage and Measuring Current works fine .. No problems)
If I configure the sweep using the instrument front panel (manually) .. It works without any problem ..
Any feedback would be appreciated ..
Thanks
