Power supply voltage reading different than K3 reading

4Z5TO
Picking nits here, everything is within spec but...

I just received an Astron power supply.  Out of curiosity I was looking at the voltage readout on the K3 and noticed it was at 14.7 VDC. I adjust the Astron to 13.8 VDC and looked at the K3 and noticed a difference in the voltaged, I would have suspected a lower reading NOT a higher reading. So checked my other ps. anyway...

Astron SS-25 @ 13.80VDC: K3 reading 14.0 VDC
Gamma HPS1-a @ 13.49VDC: K3 reading 13.7 VDC

What's going on here? I tend to trust my DMM, although...

How do I and/or should I adjust the K3 readout to actually reflect what it is receiving at the AP connectors?

I have not checked the Amps.

In config, set test mode on then, the select ADC REF.

The procedure is on page 53 of the manual.
