1. A method comprising:
parameterizing a sensor arrangement comprising a plurality of load sensors of a rotor blade of a rotor of a wind power installation for acquiring at least one load variable, wherein the at least one load variable is representative of a load acting on the rotor blade, wherein the rotor blade has at least three load sensors, the parameterizing comprising:
recording, by each of the load sensors, a load-dependent physical variable of the rotor blade, and outputting a variable indicative of the load-dependent physical variable as the acquired sensor variable,
calculating the at least one load variable from the sensor variables, wherein at least one overall calculation rule is used, forming a relationship between the acquired sensor variables of all the load sensors and the at least one load variable of the rotor blade, and having a plurality of calculation parameters, and
parameterizing the sensor arrangement, wherein the calculation parameters of the overall calculation rule are determined while at the same time taking into consideration acquired sensor variables of all the load sensors, and
adjusting operation of the rotor blade of the rotor of the wind power installation based on readings of the parameterized load sensors.
