[Elecraft] K2 voltage sense

My K2 displays 0.3 volts lower than the voltage I measure on the cathode
side of D10.  (This is after the diode drop of 0.2V)  I verified the voltage
divider R9/R10 had the proper voltage.  Also pin 7 of U3 and pin 5 of the
MCU U6 show the expected voltage.  Pin 1 of U6 reads 5.13V on the DVM.

 Is this within the expected error for the A to D conversion on the MCU U6?


Thanks,
