AUTO_BATTERY_CURRENT_ANALYZER
This op-amp analyzer can measure the current drawn by any device in a car. The analyzer works by measuring the very small voltage that develops across the battery cables when current flows. To calibrate the unit, mea-sure the current flow somewhere in the car with an accurate ammeter, then adjust the analyzer for that current reading.
