Hi. I am working on a low current measurement project using LTC6079. On the datasheet, there is a typical application circuit for "6 decade current log amplifier." I tried to simulate it in multisim, but i cannot make it work. The output voltage seems to be constant whatever input current I apply. I am not sure if I am tapping it to my test circuit right. How should i connect this to my circuit? Let us say the test circuit is just a 15V supply and a 15k-ohm resistor. Thank you!

The typlical application circuit is on this next image:
