I need to set my HP 34401A's input impedance to >10G through GPIB

Hi NI Community,

I am working on a project where I need to set my HP 34401A's input impedance to >10G through GPIB. The only option I have found for this is to set the input inpedance to auto, but since I am working with low voltage ranges the DMM always sets its impedance to 10M. So is there a way I can force the multimeter to have an input impedance of >10G with GPIB?

Thank you,
