Hello,Many thanks for your reply. I now know that I can use the ACS712 on the negative rail to measure current and obtain a positive ADC value depending upon the connection. Thanks for sharing your work.Thanks,Ian
Hello,Observing that you've used the ACS712 to measure a negative current, e.g. on the -12v rail, I'm wondering if I can use the same device to measure the current drawn on the negative rail of an audio amplifier? If so, how did you connect the ACS712 to the negative rail?Many thanks for your time,Ian
