Avoid Downprogramming Agilent 6642A

Hi,

I have connected two Agilent 6642A devices in anti-series to achieve four-quadrant operation. Now I want to measure an IV-curve of a solar cell (I ~sc~ about 9 A) using LabVIEW. But the 6642A device only has a downprogramming current capability of 2.5 A (instead of 10 A without downprogramming), so the IV-curve only will get up/down to about 2.5 A and then reach a plateau.
Is there any chance to prevent the devices from using the downprogramming option (e.g. a command in LabVIEW) or another way to achieve full measurement of an IV-curve?

Thanks,
Neddi
