I need to measure inductors with a small DC bias current. Small is a relative term and here as in won't cause any significant voltage drop in the cables of the LCR meter but enough to put my inductor near saturation. There are a few high end production test models which has this built in but it's way above my price range. The ones which has DC bias are always rated in voltage only which makes perfect sense for a capacitor measurement but assuming my DC source does the constant current limitation, am I missing something? 10 V maximum, sure, but how much current can I pass though it? Will the L-measurement DC-block the DC voltage imposed by my external current over the resistance in the wire of the coil (DUT)?
Here is one example: datasheet
