I just went to their website and watched the demo Youtube video clip about the 8081. It made me drool a little. Current ranges from 10 nA to 30A. Resistance from shunts up to 1 Teraohm. It has a dynamic accuracy capability where it will tell you the accuracy of your reading, an uncertainty display, and other cool looking features. Disclaimer: I don't work for them and am not trying to sell. Just wondering if anyone has tried the DMM and has any thoughts.
