Today I briefly tested whether the load works at all - after the purchase and "upgrade" I hadn't touched it again.
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.
