True enough. The 2002 has nominal full-scale values of 2, 20, 200, etc whereas the DMM7510 has nominal full-scale values of 1,10,100, etc.
I find the DMM7510 quieter than the 2002 and the built-in statistics of the DMM7510 save the trouble of having to run software on a PC. I can see the reasons for preference of the 2002.
