Hi, Id like to measure inrush current for various salvaged transformers (unknown windings, but probably 120/24) to the nearest 10 mA. I only have a simple DMM and soundcard scope. It seems that a clamp meter has this capability; if a clamp meter is the best approach, can I construct my own clamp meter attachment to work with my normal DMM somehow? (Im guessing not since the transient will be too fast to notice) Another idea, I could use fuses at various values, and find the one that breaks. Is there such thing as a low current variable re-settable fuse? Are there practical equations for transformer inrush current that could ballpark my measurements?
