You could easily drop 0.2 volts in the cable depending how long it
isand the gauge of the wire.
Not in six feet of #10 wire at 1.5A. Even if it were #12 the voltage
drop should be less than 0.03V (1.62 Ohms/1000 feet for #12).

Joe,
How long is your power cable from the RS-35A to your K3, and what gauge wire is
used? You could easily drop 0.2 volts in the cable depending how long it is
and the gauge of the wire.

OK, I'm sure I am overlooking something simple but I can not find
(or remember) how to calibrate the voltage display in the K3.
I had to repair one of my Astron RS-35A power supplies for the first
time in 30 years (one of the diodes shorted) and when I put it back on
line I decided to double check the K3 Volts display against the actual
output of the supply. The K3 is reading about 0.2V less than the
supply voltage.
I've been over both the K3 Owner's Manual and the K3 Assembly
Instructions but can't find any reference to calibrating the voltage
display.
