Arduinos can measure analog voltage with the function analogRead('pin number') AnalogRead returns a integer between 0 and 1023, where 0 represent 0 V and 1023 represent the reference voltage. The reference voltage is by default the voltage that powers the Arduino's inner circuits, and is the voltage you can measure on the 5 V pin o So you cannot setup the Arduino voltage reference for measurement at the A REF pin. Therefore you can't calibrate it directly. You would either assume that it has the stated value or accurately measure the Vcc supply then take an ADC reading (but remember the ADC has its own errors as well!). One way that would eliminate ADC errors is to feed in a variable voltage to an ADC input - which you. Arduino data logger - Voltage measurement. Most of the time the voltage will be held to around 12V by the battery, however, if the battery is disconnected the voltage in the circuit can rise much higher.
