How come when using list mode on 85xx DC loads, resolution for a power list is 10 mW where as specification says 1 mW?

Q:
How come when using list mode on 85xx DC loads, resolution for a power list is 10 mW where as specification says 1 mW?

A: The specification of 1 mW resolution applies to front panel single setting in CW constant power mode.  You can set a value with up to 1 mW resolution.  In list mode, power list is limited to 10 mW due to limitations in CPU space required for the computation.

However, at any given point, the measured values read and displayed on the meter still still retain a measured value of 1 mW resolution.  This can be verified when you toggle the display by pressing the rotary knob to show power meter instead of voltage and current meter.
