What exactly are you looking to do? The data sheet is pretty specific. Using the 0 to 6 amp version you should see an output of between 0.25 and 2.75 when powered by 5.0 V and using the internal reference. The data sheet page 15 shows the pinout to change the primary resistance. Unless you are concerned about that 6, 7, 8, and 9 (OUT) are tied and 2, 3, 4, and 5 (IN) are tied. Everything is in the data sheet as to setup. What exactly in detail are you wanting to do?
