Is there any way to accurately measure the current draw of an oscillating DC circuit? I have a circuit that oscillates at 6 kHz for .6 seconds and repeats every 1.3 seconds and is supposed to draw 250mA. Using a digital multimeter to read current, the numbers are all over the place. I assume this is due to the current turning on and off at such a high rate and the much slower speed of the digital display. When I press the MAX button, it shows a number that I didn't see during direct reading. Would this be the actual current draw? Can a digital meter read a current that only lasts for about 166 microseconds?
