The current flowing in a DC circuit can be measured by measuring the voltage accross a series resistor. The resistor value is chosen so that the voltage across it is within the measurement range of the XO (0.4-1.8V XO1, 0.17V-3.0V XO1.5) and as low as possible consistent with that to minimise influences on the measured circuit. | The current flowing in a DC circuit can be measured by measuring the voltage accross a series resistor.
