LabView Keithley 6485 Current measurement error

[YogeshL]

Hi, I'm trying to measure current using a Keithley 6485 Pico ammeter. I've developed few LabVIEW VI code, which I'm attaching. The code is communicating with the 6485, but the measurements are in the range of 10^(-14). Could someone please help me figure out if I'm missing something?
