U6-Pro vs. U6

The U6-Pro has all the features of the normal U6 with the addition of an auxiliary low-speed high-resolution (24-bit) sigma-delta ADC. Under software control you specify a resolution setting that determines whether the high-speed converter or high-resolution converter is used for any given reading. The high-resolution converter is only an option in command/response mode, and is not used in stream mode.

Analog input resolution from the high-speed converter (U6 and U6-Pro) varies from 16.1 bits (RMS or Effective, resolution index = 1) at max speed (<1 ms conversion time), to 19 bits (resolution index = 8) at slower speeds (2 ms conversion time). Analog input resolution from the high-resolution converter (U6-Pro only) varies from 19.7 bits (RMS or Effective, resolution index = 9) at max speed (4 ms conversion time), to 22 bits (resolution index = 12) at slower speeds (160 ms conversion time). For more detail see the Command/Response Data Rates and the Noise and Resolution Tables. The U6-Pro has an obvious benefit at resolution index = 12, but there is also a more subtle benefit when using higher gains (x100 and x1000) as the time at resolution index = 9 is better than most times from the high-speed converter.

One more benefit to the U6-Pro, is that it has very high 50/60 Hz rejection when set to resolution index = 12.
