Hoping someone can explain this to me.
I created a breakout for my CurrentRanger (attached) with a USB micro female receptacle on one side, and USB A female on the other. GND is connected to GND. VIN and VOUT are not connected to each other. Instead they are broken out by plated holes where I can connect my CurrentRanger to the source and the load. (I went for a little fun and tried to make the breakout actually look like it is being broken.)
OSHPark sent me three copies, as they do.
To copy 1 I soldered IC test clips and attached the LPL Shop banana plugs.
https://lowpowerlab.com/shop/product/183To copy 2 I soldered female headers and attached Dupont male-male connectors, with the other ends clipping into the green thumb terminals.
I measured the current used by one of my projects. With setup 1 (banana plugs) I was reading (if memory serves) 50-60 mA. With setup 2 (Dupont wire) I was reading (if memory serves) about 32 mA.
Question: is this a known thing that the hookup to the DUT can make such a difference in the readings? Or is something else going on that I should look into in my setup?
