This power supply as noted by the numerous posts and the original video has so many issues that the thermal issue is just the icing on a rather nasty cake! What Dave thought after the first video only Dave knows. I know that I was completely turned off by the terrible rotary knob design and its tracking, the ergonomics of the unit as a whole and the voltage display not showing the exact set voltage plus that nasty spike. The list goes on but surmise to say it was pretty clear to me from the original video that the power supply even before the tear down was not that good, of course that's just my opinion. I guess we will know for sure what Dave was thinking if he keeps the repaired revision as his main bench supply.
You had your conclusion in mind before you ever saw the video, and before you ever knew the specs of this supply. I noticed you have an irrational hatred of it and inflate every criticism to be the worst thing ever, and gloss over every benefit as useless.
Corporate666 do you work for Rigol or are you the forums official attack dog when anybody has something negative to say?
First of all how could I have had a conclusion about the 832 before I even saw the first video? I had never even heard of the DP832 until Dave did the first video! Based on that video I made it very clear that I did not like the "DP832 Precision Power Supply" and stated my reasons why. How do you then come to a conclusion that I have an "irrational hatred" of it when my initial reasons are not even under dispute?
Dave did not like the rotary encoder design or the numeric pad, I did not like the rotary encoder or Pad.
Dave did not seem pleased with the way the encoder responded, I did not like it at all.
Dave did not like that Nasty glitch, I did not like it either.
During the video it was clear that the set voltage versus the output voltage under no load did not correspond, I said I did not like that at all, is something wrong with that opinion.
The video showed one of the outputs having a small current draw when nothing was connected, that's another issue I did not like.
No sense voltage on a precision power supply, whats a person supposed to do, dedicate a precision meter to monitor the DUT?
And my main reason was that I did not like the ergonomics of the design and the incorporation of so many rarely used features because I knew it was just a selling point distraction that would mean less design money would be available for making a supply that was actually going to be precise and reliable. The Teardown and the First video proved that to be correct.
Case in point... "terrible rotary design". I don't know what is terrible about it? It is better than the knob on my Agilents. There is nothing wrong with it's tracking. It works great.
Yes it is terrible and for the reasons I stated above!
My agilent knob fits nicely between my two fingers and I can turn it very slowly and precise while looking at my other equipment, something that seems very difficult to do with that encoder. It also tracks my movements perfectly and the display matches my every movement, the 832 does not do that.
Case in point... you say "as noted by many posts has numerous issues". The comments from owners have been overwhelmingly positive.
Really!! They sound either upset or worried and several have pointed out other issues.
Case in point... you say "what Dave thought, only he knows". No, we all know what he thought because he told us.
I assumed Dave opened the box for the first time while filming the video, he made many positive remarks and some negative remarks. Most people don't make up their mind about anything that they see for the first time until they mull it over for a few hours, sometimes days. That's why snap purchases are typically regretted. So it was logical to assume that Dave's opinion could be in Flux so I had no way of knowing what he thought the next day, his mind might have changed. That's why I simply stated only Dave knows.
Case in point... you say "pretty clear to me it was not that good".
You have hated this power supply from day one... I have no idea why. But it clearly has very little to do with this power supply itself. The thermal problem IS a deal breaker, but your complaints predated that discovery by a long time.
Yes; it is pretty clear to me! That's my opinion, in your world is there no room for people to have opinions that differ from yours?
"You have no idea why I hate it": I stated the reasons in every post
"The thermal problem is a deal breaker for you": For some people they may not see it as a deal breaker at all, they may just stick a bigger heat sink on it or just keep the Lid on and sell it in 2 years. Once again "Deal Breaker" is your opinion and it's not shared by everyone. My opinion was formed from the first video because I have already been reemed up the arse buying equipment that had lots of dazzling features at the expense of being really bad at doing the core thing it was designed to do.
Whats the bloody point of having a Blinged out Linear Precision Power Supply if it's not Precise and it's not reliable?
And all those "Benefits" you think I should be praising are bloody useless if it's primary functions don't work properly
Corporate666 why don't you spend your time on the bloody rude people I see making posts on this forum instead of hammering people like me who are just trying to have a civil discussion.
You seem to be tracking my posts, so tell me how many times have I said a reviewed piece of equipment was a POS? It would also be helpful to know if that's not allowed on the forum because it sure feels that way.
