Re: AndyMark Nano Break In

We use a clamp on ammeter when just running DC off a battery. We also use a current shunt such as this one: http://www.powerwerx.com/tools-meter...0-amp-max.html It's just a calibrated resistor. You then put your voltmeter across it and measure millivolts ...1 mv per amp.

Al Skierkiewicz posted something a while back about using something like 1 ft of #10 wire also dropping 1 mv per amp. Of course it's not as accurate as a calibrated current shunt (above) but it would certainly be fine for breaking in motors. You just measure the voltage across that length of wire in series with the motor wires.
