K3 -ADC Ref - Change for different Power Supplies?

a simple question with probably an obvious answer, but that's why i
get paid the big bucks!

i've been running my K3 off one power supply and measured the voltage
at Pin 2 of the ACC at 4.96, so that's what i set up in the CONFIG.

today i got one of the tiny Gamma HPS-1a supplies (its so small its
hard to imagine its real) and just for giggles measured the voltage
at Pin 2, and its 4.93.  I can easily enter this into the CONFIG
menu, but should different PS give different results?  (i did measure
a difference in the PS output voltages...  Supply "A" was 13.75 and
the HPS-1a is 13.61.

can't imagine any of this will make a lick of difference, but always
better to ask.

thanks in advance!
