Much less expensive source for what I believe is the same sensor.  I have this one in my plane.

I purchased a ACS712 Hall effect sensor from eBay for $2 to play with on the work bench.  I did not install it in an airplane.

The manufacturer intended that the current carrying wire be cut and connected to the green terminal strip.

If installed in an aircraft, it is not desired to cut a heavy wire which would introduce two more failure points.

So I just laid the uncut wire across the IC and tested it like that.  It worked fine.

If one were to actually install this sensor in an aircraft, the wire being monitored could be glued to the IC using E6000.

Three wires need to be connected, +5VDC, ground, and output.

Your ammeter display should have the ability to be calibrated.
