摘要： A mobile current measurement apparatus, a current measurement terminal, and a current measurement method are provided. More particularly, the present disclosure provides a mobile current measurement apparatus, a current measurement terminal, and a current measurement method capable of measuring a current of a Device-Under-Test (DUT) by using a wireless short distance communication. The method of measuring a current by a current measurement apparatus includes detecting a voltage converted from a current of a device-under-test, compensating the detected voltage by using a voltage offset generated by an amplifier of the current measurement apparatus, and measuring the current of the device-under-test based on the compensated voltage.
