My current DMM (a $10 ebay special) has a too high internal resistance when measuring in the 10A DC setting. I do a lot of work with battery powered LED lights, so even a small internal resistance will have a BIG effect on current draw. (today I built a very bright light and wanted to check how much current it was drawing- rigged up my multimeter and it stopped being very bright and drew 1.5A- I suspect without multimeter it drew over 3A but have no way to check)
Can anyone recommend a <$50 multimeter that will accurately measure high currents on low voltage sources without affecting the system being measured?
