Accurate Low Amp Current Probe Advice
KungFuJosh:
Holy shit, Batman! Martin, when you said this thing was big, I had no idea how ridiculous it is. 🤣🤣🤣
Only problem is that the probe that came with the set has a small issue with the switch. |O

Which forms part of the jaw locking device.......

I still have a few parts... 8)

I set the SDG2122X output to 369mV at 1kHz, and that measured 5.00mA on my SDM3065X.
Then I setup the AM503B at 1mA/DIV with 20M limit.
This looks pretty good, right? Did I do anything stupid in my setup? 🤔
...because after reconnecting to the SDM, I'm getting 1.713mA. I assume there's an equation I should know here. 😉
Martin72:
As I mentioned before, you set 10mV/div, 1:1 and 50Ohm on the scope itself and leave it as it is.
Everything else (bandwidth limitation, scaling, AC, DC) is set on the 503B.

So you used a 73.8 ohm resistor as a load?
