Re: Measuring Amperage
Be sure to purchase some extras and expect to let out some smoke. We used a similar device a few years ago. It worked great as long as the motor didn't stall.
You might want to search on here for "stang sense". You can use a 12" piece of # 10 Ga wire and make a 0.001 ohm resistor. With a voltmeter that will read milli volts it makes a great ammeter. A simple op amp circuit gets you a signal to read with the cRIO.
