Hi,I'm trying to measure how much current my servo motor pulls in order to setup the circuit properly (I have to reduce 9V to 6V for the servo). The servo is a Futaba S3003.The problem is, I can only get normal behavior when my multimeter's plug is in the 10A (unfused) connector. I get readings between 0.1 and 0.4 (therefore 100 and 400 mA), but when I plug the cable into the "mA" (fused) connector the servo behaves very strangely, and stops responding to commands.
I have 5 x S3003 plugged into a 5.2A 6V power supply.
Use a scope and sampling resistor, an analog meter will only give accurate information about RMS (Root Mean Square) voltages and only for periodic waveforms that are sinusoidal in nature. As you depart...
