Very good data!
I am curious about one part of the warmup process. At around 7 minutes, the
power jumps up radically, which you attribute to
the outer oven kicking in. It has often been stated on this list that the outer
oven was intended for use during really cold
starts, which I would expect should cause it to kick on almost immediately
during a very cold start. I am assuming your start
was from room temperature. For a room temp start, I wouldn't expect it to kick
on at all if it's purpose was as reported. Or
do I have the oven functions reversed?

I can confirm Ed's tests. Attached is a similar test that I did on my
Z3801A. If it matters, mine is the 24V nominal version. My test was
done at 27V. The power supply was an HP6622A with GPIB. I wrote a
program to query the current being drawn each second. The current value
was later converted to power.
