This is as short as I can make it. When I first noticed the difference in the K3 meter reading compared to my DVM, I wondered if I needed to calibrate something, and I wondered if the K3 meter was linear. The answer is; no, and can't tell.
K3 volt meter at key up: 13.7 V DVM at PS: 13.71 V K3 volt meter at key down: 12.8 V DVM at PS: 13.68* V K3 12 volt out jack w/key up: DVM 13.01V K3 12 volt out jack w/key down: DVM 12.28* V (at first glance, this leaves some questions) In summary; --I measure no Vd through my homebrew distribution blocks. --I calculate no Vd through the Power Poles. (Difficult to test through.) --There is minor drop in power wires. --K3 12V out jack reads 1.4 V lower than PS voltage at key down. Two diodes in circuit to the 12V out jack explain that drop. --The 12V out jack cannot be used to measure voltage drop from PS. --Unsure of the VM circuit test point for linear comparison. No external access.
