Using mux-4051 to measure IV chaeacteristics of 4 solar pixels(cells) one at a time

[jyot445]

Hello, 

After doing measurement of one solar cell,I want to do the measurement of six solar cells IV characteristics one at a time (automation) 

For this I have NI USB-6501 as a input control and I am using mux 4051 as analog switch .

But it doesn't seem to work so.

The USB 6501 is working in a correct manner(switching the correct line when given the command)

Any idea about it ( or where is it going wrong)?

Thanks

Judging by the only image you shared...

You did not connect any of the wires!

Now if you have actually wired up the mux, then share the code you are using (in LV 2014 or such) so that we can do more than just guess.

Spoiler

But I am sticking with my first guess that you did not wire anything up.
