We all like Test equipment Dave thats not the point! May I ask you what is the point of someone owning $20,000 worth of test gear if all they are doing with it is running 555 timers and basic Op-Amps? Thats the bloody problem with all of this and below I will qoute what I consider a classic post in this thread that sums it up completely.

What's wrong with someone being into test gear? I am into watches. I have about 60 watches. I just like them. Old, new, mechanical, automatic, eco, digital, cheap, expensive, plastic, metal, ones I made myself, ones I had made, ones I got at yard sales, and everything in between. Why should people not indulge their desires if they have the means and desire to do so? Are people neglecting to feed their kids because they want that new DSO?
You understand how to read the Time, Right?
Why collect a hundred books if you can't read or 60 watches if you don't know how to tell time? Why buy test equipment if you really don't know how to use it?
That seems incredibly arrogant to me. Some of the stuff we make is out of various exotic woods. I cut them on the CNC machines. I've occasionally had woodworking types act mildly offended that we use CNC machines to cut wood
These types are funny, aren't they? Sometime, I want to post a design for a tube amp on an audio forum, with both plate and filament powered by DC-DC converters just for shits and giggles.... and lots of SPICE simulation...

look on his face like someone shoved a lemon up his ass

May I ask you what is the point of someone bothering with hobbies at all if they could contribute as much to society as a whole by sitting around scratching their ass?
Because it gives them pleasure. They like it.
How did you measure this? It is not plausible that all 8 power supplies have a buckle at 0.01V, 0.1V and 1V.

Super accuracy of the built in meter ? Nah, I always use my trusty Fluke 87 III or other quality meters to ensure that the voltage and current are correct.

I have never trusted built in meters since the days when PSU's just had cheap moving coil meters. I would rather the manufacturer spent the money on the unseen elements of the design. When you think about the cost of a Fluke quality meter, how likely is it that a PSU manufacturer will spend that sort of money on their internal voltage and current meter design ?
Yes Dave this post is a perfect example of what EE equipment is all about, how many colors can the display show, better looking UI's with more menu features And oh the older Agilent sucks because it does not have a Blinged out display
Well at least the companies that can create the most high tech looking displays are now making money, who cares how well the equipment works, just so long as it looks good
An interesting little comparison of the DP832 to several Agilent's, 2 old HP's and 2 old Power Designs. This chart is annual accuracy of set voltage in percent of value from 1mV to 30V. On the DP832 I am using the readout accuracy which is better than its programming accuracy. They are listed in roughly least to best from top to bottom on the legend. Roughly because it depends what range of voltage you are comparing. The Agilent b29XXA is a >$5000.00 SMU

a 2.2? 320×240 LCD display that is a vast improvement on the old stock seven-segment numerical display.
