Formula
The formula for converting output voltage into DC Amps is: DC Amps = (V - 2.5) / 0.02083
Looping to Increase Resolution
If you need to measure less than 75A and want better resolution, you can loop the cable through the sensor a second time. The current value you get back from the sensor will be doubled, since it's measuring the same wire twice at the same time. You can divide this value by two, thus halving the maximum range from ±75A to ±37.5A, but effectively doubling the resolution of your measurement.
You can loop the cable through any number of times to repeat this process, although there will be diminishing returns as your resolution approaches the noise tolerance for the sensor. You could also cause problems with the measurement if the wire window is too full, if the wires shift around and push up on the clip.
