A precision amplifier measures the voltage across the 0.1 ohm, 1% sense resistor. Since the amplifier maximum input difference is ±۳۲۰mV this means it can measure up to ±۳٫۲ Amps. With the internal 12 bit ADC, the resolution at ±۳٫۲A range is 0.8mA. With the internal gain set at the minimum of div8, the max current is ±۴۰۰mA and the resolution is 0.1mA. Advanced hackers can remove the 0.1 ohm current sense resistor and replace it with their own to change the range (say a 0.01 ohm to measure up 32 Amps with a resolution of 8mA)
