Magnetic Current Sensor Manual
... If you change the magnetic sensor, you should perform the zero procedure again as every sensor will have a slightly different zero current output voltage. Now set an estimated sensor gain. You can use the gains from some of the examples. Smaller gain numbers mean bigger field per current unit, large ...
