You mean constant voltage?

3711 Adjusted and fully in-spec now.  stupid callabs 'can't adjust' ... too lazy to open the box or download the cal manual... ah well their los, my gain.

Great! I figured that was the case.  Another advantage for owners is that the Array's don't need much in terms of high end metrology gear either, and is easy to self maintain; one can even make small adjustments on the fly while the unit is operating to compensate for settling, due care taken naturally.

Looking forward to your progress and to LaurenceW's updates on his close case firmware based calibration his new Maynuo for comparison.

Yes

Yes, that has pros and cons, its not entirely a loss.  Since V and I are related phenomena, tests meant for CV can be done with CC for practical reasons [ that is, not following the manufacturers precise test protocol which requires CV but getting the same result ] e.g. plotting a V x I curve for a battery or PSU.  However, it may not be possible to to test NiMH chargers; if it has input protection, it will first check output voltage from the load before it switches on, so most good chargers will see the connection as open circuit or short circuit and refuse to start.
