I'm using a ACS723 (similar to ACS712) exactly as recommended by the datasheet (see attachment for schematic) to measure the current load of a Brushless Motor. The sensor reads accurately when I connect it to a Multimeter between the load and the sensor. But once I disconnect the multimeter, the sensor does not read accurately. We are talking like ~50-75% less accurate. Any help will be appreciated.
Also, the Sensor is far away from the motor; to avoid interference. Any suggestions of what can cause this offset/bad reading? I'm not getting noise.
