METHOD FOR SETTING UP A CURRENT SENSOR

摘要

The invention relates to a method for setting up a current sensor (4) having an internal resistance which is dependent on the current (12) which is to be measured, wherein the internal resistance is set to a setpoint voltage drop (30) as part of a regulation (8) of an actual voltage drop (22) across the current sensor (4), comprising calibration or checking the plausibility of operation of the current sensor (4) based on a characteristic curve (38), in which the current (12) which is to be measured is compared to a variable (28) which is dependent on the internal resistance or to the internal resistance.
