As mentioned in another thread, i bit the bullet and ordered one of these. Double 30V 5A output with a third 2.5/3.3/5V 3A output
http://www.attenelectronics.com/productBody.aspx?id=103&bid=25&sid=130The price was just under €230 with Fedex delivery.
The box looked like it had been through the wars when it arrived and sure enough when i opened it there was some damage

Luckily there was nothing behind that part of the case so i fired it up. Hmmm, channel 1 display wasn't quite right

Poking with a finger sorted it

Time to open it up so! Couple of random shots. Seems to be up to the same standards as my other Atten stuff, all wires tired and connectors glued in place.

I took the screen out and one of the plastic screens at the front was a bit out of place fixing that and putting it back together seemed to do the trick although both screens are a little tempermental., sometimes needing a poke to display properly. I'm going to take it apart and put some spacers in to keep an even pressure on the screens
Couple of measurements with my new fluke, no load

If someone tells me what sort of tests to do i'll do them when i get a chance
Can someone how parallel/series mode works? I can't undersdtand the manual
Also, only negative i see so far (apart from the screens!) is that theres no switches for the outputs, only a main power switch
