Abstract

A measurement apparatus has a current sensor and at least one A/D converter, which current sensor has at least two channels (CH1, CH2), via which channels (CH1, CH2) the current sensor (30) respectively provides a measurement signal (CH1_SIG, CH2_SIG) characterizing the current. The at least two channels (CH1, CH2) include a first channel (CH1) and a second channel (CH2), which second channel (CH2) is designed to measure a greater maximum current than the first channel (CH1). Also described is a method for measuring a current flowing through a conductor by way of the measurement apparatus.
