Siglent SDL1000X/SDL1000X-E Electronic Load
Detlev:
I just measured my SDL1030X, the values look good here. Picture 1 with no load and picture 2 with 1A load. I can live with these deviations quite well. The SDL could be better at ampere.
A possibility for calibration would still be very good.
Have a nice day

Detlev,
That's better than what we are seeing with our SDL1000X.
BTW do you see the last couple digits bouncing around on the 150V range, even with 2^14 averaging we still see this.
Thanks for showing :-+
Best,

On my unit, I have crimped fork connectors to the sense wires and connect them directly to the input posts for normal use. This already eliminates some error and seemed to make the reading a little more stable.

That's a good idea with the sense line crimped with the heavy current cable if that's what you are doing, good idea either way. We have some heavy 10AWG & 12AWG flex cable on order for making up some 30A cables for upcoming testing and may make up a pair with the sense lines crimped with the lug. This should effectively move the supply or load "reference terminals" to the cable lug end whichever way it's connected, and not have to deal with two lugs on one terminal which is often a problem with some terminals.
Best,

Have never been really happy with binding posts on DC loads, when virtually everyone uses banana plugs anyways. I was tired of the custom adapter cables I DIYed dangling around, and I wanted something a bit beefier than the PCB adapter boards out there (e.g. https://www.tindie.com/products/labshack/dc-electronic-load-banana-plug-adapter-pcb-only/)
I ended up cutting a couple of parts out of 1mm thick solid copper sheets, and soldered 4mm safety banana jacks onto it. I did have to snip away the lower right rubber bumper to have it fit properly, but the binding posts extends beyond the bumper, so it wasn't going to do anything anyways. ::)
I quite like this little accessory, it is quite solid and resistance should be as low as it gets. There is a possibility the binding post may come loose and the copper parts will short out, but I have wrenched hard on the binding post with a pair of Knipex Cobra, think I should be good.

Early in this thread a member found binding post caps that take banana plugs.
First pics here and a couple posts later a link to where he got them from on Aliexpress.
