hi, i'm new to this forum..but have been reading for a while....
i've had this 8500 RD for about 3 months.....and i usually leave it to read my voltage....so while driving it reads somewhere around 13.4-13.6 volts....
I just got my 8500 X50 and i noticed that this one fluctuautes at around 13.9-14.1 while driving....
anyone know what's the reason for the discrepancies....
i bought both used....never got a "self cal" message....
