Siglent SDL1000X/SDL1000X-E Electronic Load
Martin72:
I had received the service manual with calibration instructions from siglent last week and had it here for download at short notice, I can post the link again.
The explanation from siglent as to why this document is no longer downloadable was that the script had caused "confusion for some" and they had therefore taken it off the net again.
Martin72:
Here again the link (will be deleted soon):
Edit: Link removed after four days.

Thanks for that link.

Today I briefly tested whether the load works at all - after the purchase and "upgrade" I hadn't touched it again. :-X
I will definitely test it in more detail and I think I will open a separate thread for this, as it would quickly get lost here.
It will be a few more weeks before I'm ready, because I have to wait for my new scope.
In the meantime I can get some other things, because when I was looking around I noticed that all my supplies can only deliver a maximum of 3A...a bit low.
Let's see.
As I said, briefly tested the SDM3065X, which was still calibrated until the summer, as a reference and recorded three values.
First of all: This connection(load connectors)....Who comes up with something like this...
Terrible, I'll have to change that before the test.
Then:
These were small currents, you shouldn't forget to switch the range at the load, otherwise the display is inaccurate.
Set Current: Measured Current: Deviation:
500mA 0.499504A -0.10%
1A 0.999558A -0.04%
1.25A 1.249561A -0.04%
I think that's very neat.
Here is the deviation display load/SDM3065X:
Load: SDM3065X: Deviation:
0.4992A 0.499504A -0.06%
0,9996A 0.999558A -0.004%
1.2496A 1.249561A -0.003%
I also think that's very good.
And as I think about it, this is something I can already test, up to 3A.
I will probably create a table with more values.
Martin72:
I have now recorded a few more values, used a different power supply unit and set not only the current range but also the voltage range of the load (5A/30V).
Further, more detailed tests and impressions as mentioned later and in a new thread.
You should not be influenced by the first values, such small currents cannot be precisely mapped by this type of load, so this is not a shortcoming.
